    Interpretive Summary for October 1, 2021
    Three Point Shot


    resize iconView Larger


    Last week the U.S. Food and Drug Administrationexternal icon (FDA) issued an emergency use authorization (EUA) for a single booster shot* of the Pfizer-BioNTech COVID-19 vaccine. Certain populations are now eligible to receive a booster shot of the Pfizer-BioNTech vaccine at least 6 months after receiving their second Pfizer-BioNTech shot. These populations include people ages 65 years and older, people ages 18 years and older who have underlying medical conditions, and people ages 18 years and older who live or work in high-risk settings.

    The COVID-19 vaccines approved and authorized in the United States continue to be effective at reducing the risk of severe disease, hospitalization, and death. COVID-19 vaccination can also reduce the spread of disease overall and help protect the people around you. However, recent data show that protection against asymptomatic, mild, and moderate disease may decrease over time. The reduced protection may be due to both decreasing immunity over time and the highly contagious Delta variant.

    COVID-19 vaccination, along with layered prevention strategies, continues to be our best defense against severe disease. People who are unvaccinated remain the most vulnerable to COVID-19. To end this pandemic, it is critical that all people get vaccinated as soon as they are eligible. To find a vaccine provider near you, visit Vaccines.gov or your state or local public health department website. Talk to your healthcare provider if you have questions about whether a Pfizer-BioNTech COVID-19 booster shot is appropriate for you.

    *Booster shots are doses of U.S. approved or authorized vaccines that are given when protection from initial vaccination is likely to have decreased over time.

    Note to readers: CDC’s COVID Data Tracker recently released a COVID-19 Vaccine Effectiveness page, which allows users to view COVID-19 vaccine effectiveness at protecting against hospitalization and infection.


    Reported Cases


    The current 7-day moving average of daily new cases (106,395) decreased 13.3% compared with the previous 7-day moving average (122,659). A total of 43,289,203 COVID-19 cases have been reported as of September 29, 2021.

    SARS-CoV-2 Variants


    Currently, the Delta variant is the only variant classified as a Variant of Concern (VOC) in the United States. There are no variants classified as a Variant of Interest (VOI) and there are 10 variants classified as Variants Being Monitored (VBM). VBM do not pose a significant and imminent risk to public health in the United States due to their very low prevalence, which is currently estimated to be less than 0.1%.

    Nowcast projections* for the week ending September 25, 2021, estimate the national proportion of cases attributed to the Delta variant to be greater than 99%. Nowcast estimates indicate that Delta will continue to be the predominant variant circulating in all 10 U.S. Department of Health and Human Services (HHS) regions, circulating at greater than 98%.

    *The median time from specimen collection to sequence data reporting is about 3 weeks. As a result, weighted estimates for the most recent few weeks may be unstable or unavailable. CDC’s Nowcast is a data projection tool that helps fill this gap by generating timely estimates of variant proportions for variants that are circulating in the United States. View Nowcast estimates on CDC’s COVID Data Tracker website on the Variant Proportions page.

    Vaccinations


    The U.S. COVID-19 Vaccination Program began December 14, 2020. As of September 30, 2021, 392.9 million vaccine doses have been administered. Overall, about 214.3 million people, or 64.6% of the total U.S. population, have received at least one dose of vaccine. About 184.6 million people, or 55.6% of the total U.S. population, have been fully vaccinated.* As of September 30, 2021, the 7-day average number of administered vaccine doses reported (by date of CDC report) to CDC per day was 726,899, a 6.4% increase from the previous week.

    CDC’s COVID Data Tracker Vaccination Demographic Trends tab shows vaccination trends by age group. As of September 30, 2021, 93.8% of people ages 65 years or older have received at least one dose of vaccine and 83.3% are fully vaccinated. More than three-quarters (77.3%) of people ages 18 years or older have received at least one dose of vaccine and 66.9% are fully vaccinated. For people ages 12 years or older, 75.5% have received at least one dose of vaccine and 65.1% are fully vaccinated.

    COVID-NET: Trends in Hospitalization Rates in Children Ages 4 Years and Younger Not Eligible for Vaccination


    CDC’s Coronavirus Disease 2019-Associated Hospitalization Surveillance Network (COVID-NET) shows that hospitalization rates are still increasing in children. Recent weekly rates of COVID-19-associated hospitalizations for these children have steadily increased since the end of June 2021. For the week ending September 11, 2021, weekly rates of COVID-19-associated hospitalization in children ages 4 years and younger are 3.3 per 100,000. These recent rates are the highest seen for this age group during the pandemic. Unlike adults, children younger than 12 years of age are not yet eligible for any of the available COVID-19 vaccines.

    Interpretive Summary for October 8, 2021
    Health Equity and Disability


    resize iconView Larger
    COVID-19 cases, hospitalizations, and deaths are once again declining in many parts of the country. Sadly, the United States reached a grim milestone this week, surpassing 700,000 total deaths from COVID-19. Studies have shown that COVID-19 does not affect all population groups equally. Some people with disabilities might be more likely to get infected or have severe outcomes from COVID-19 because of underlying medical conditions, group living settings, or systemic health and social inequities.

    It is important that all people, including people with disabilities and people who provide support to people with disabilities, get a COVID-19 vaccine. Many people with disabilities face significant challenges accessing COVID-19 vaccination services and may need support. A recent analysis of CDC survey data shows that some adults with a disability* were more likely to report difficulty getting a COVID-19 vaccine compared to adults without a disability. Despite disparities related to COVID-19 vaccine access, adults with a disability are less likely to report being hesitant about vaccination compared to adults without a disability.

    People with disabilities need health care and health programs for the same reasons anyone else does—to stay well and active. Good health is important to be able to work, learn, and be engaged within a community. CDC has resources to support people with disabilities and those who care for them. CDC’s Toolkit for People with Disabilities includes guides for increasing disabled persons’ access to vaccinations along with COVID-19 FAQs. To find a vaccine provider near you, visit Vaccines.gov or your state or local public health department website.

    *In assessing COVID-19 vaccination status for this analysis, CDC asked “Do you have serious difficulty seeing, hearing, walking, remembering, making decisions, or communicating?” Respondents who answered “yes” were considered to have a disability, and those who answered “no” were categorized as having no disability.

    Note to readers: CDC’s COVID Data Tracker’s Health Equity Data page catalogs current health equity-related data on the COVID Data Tracker that align with populations and place-based focus groups identified in the CDC COVID-19 Response Health Equity Strategy pdf icon[86 KB, 5 Pages]. On this page, users can find data on COVID-19 vaccination among people with disabilities, underlying medical conditions, COVID-19 vaccination equity, and more.

      Healthy Futures


      resize iconView Larger
      Fewer cases of COVID-19 have been reported in children (ages 0-17 years) compared with adults.1-3 Rates of COVID-19-associated hospitalizations are also lower in children of all ages compared to adults, but some children develop acute COVID-19 symptoms requiring hospitalization.4 All eligible people, including adolescents ages 12-17 years, should get vaccinated to help stop the pandemic. Everyone in the United States 12 years and older is eligible to receive a COVID-19 vaccine, yet vaccination coverage among adolescents is lower than in older groups.5

      Children with underlying medical conditions, including obesity, are at increased risk for severe COVID-19 illness* compared to children without underlying medical conditions. Children diagnosed with obesity may experience worse outcomes from COVID-19.6 A recent CDC study looking at body mass index (BMI) suggests that many children and adolescents gained weight faster during the COVID-19 pandemic than before the pandemic.** This was especially true among children and adolescents who had overweight or obesity before the pandemic.7

      In addition to the steps everyone should take to slow the spread of COVID-19, people can help protect themselves and their families by eating a healthy diet, being active, getting enough sleep, and learning to cope with stress in a healthy way. Parents and caregivers can further protect their children by maintaining well-child visits and recommended vaccines, including COVID-19 vaccines for children ages 12 years and older. If you have questions about childhood vaccines, talk with your child’s pediatrician or healthcare provider. To find a vaccine provider near you, visit vaccines.gov or your state or local public health department website.

      *Severe illness means that the person with COVID-19 requires hospitalization, intensive care, or a ventilator to help them breathe.
      **Body mass index (BMI) is a measurement that takes into account a person’s weight relative to their height. Although children are expected to have increases in BMI as they grow, rapid increases can raise concern over too much weight for health. The rate of BMI change tells us how much BMI changes over a specific time period. This study looked at monthly changes in the rate of BMI at two time periods —before the COVID-19 pandemic (January 2018-February 2020) and during the pandemic (March-November 2020). This study involved a cohort of 432,302 children and adolescents between the ages of 2-19 years.

      Note to readers: CDC’s MMWR is excited to announce the release of two new web pages. MMWR’s updated COVID-19 Reports web page features a user-friendly experience, including the latest on COVID-19 vaccine safety and effectiveness, as well as links to MMWR’s Featured Report, MMWR podcasts, and MMWR graphics pages.

VBM do not pose a significant and imminent risk to public health in the United States due to their very low prevalence, which is currently estimated to be less than 0.1%.

      Nowcast projections* for the week ending October 9, 2021, estimate the national proportion of the Delta variant to be greater than 99%. Nowcast estimates indicate that Delta will continue to be the predominant variant circulating in all 10 U.S. Department of Health and Human Services (HHS) regions, circulating at greater than 99%.

      *The median time from specimen collection to sequence data reporting is about 3 weeks. As a result, weighted estimates for the most recent few weeks may be unstable or unavailable. CDC’s Nowcast is a data projection tool that helps fill this gap by generating timely estimates of variant proportions for variants that are circulating in the United States.

        Interpretive Summary for October 22, 2021
        Prevention is the Best Defense


        resize iconView Larger
        COVID-19 cases, hospitalizations, and deaths continue to decline, while the number of people who have received at least one dose of a COVID-19 vaccine continues to increase. As of October 21, 2021, more than 189 million people in the United States (approximately 57% of the total U.S. population) are fully vaccinated against COVID-19. Everyone should get vaccinated against COVID-19 as soon as they are eligible, including people who have already had COVID-19.

        Studies show that the incidence of COVID-19 infection, hospitalization, and death is higher among people who are unvaccinated compared to people who are fully vaccinated. A new COVID Data Tracker page shows that in August 2021, people who were unvaccinated were 11 times more likely to die from COVID-19 than people who were fully vaccinated. A second new COVID Data Tracker page shows that people who were unvaccinated were 12 times more likely to be hospitalized with COVID-19 compared to people who were fully vaccinated.* Additionally, a recent CDC-supported evaluation found that two doses of Pfizer-BioNTech vaccine were 93% effective at preventing COVID-19 hospitalization in adolescents ages 12-18 years.

        Getting vaccinated against COVID-19 helps protect people from getting sick with or severely ill from COVID-19. People who are unvaccinated remain the most vulnerable to COVID-19. COVID-19 vaccination, along with layered prevention strategies, continues to be our best defense against severe disease. Getting a COVID-19 vaccine is fast, easy, and free. To find a vaccine provider near you, visit vaccines.gov or your state or local public health department website.

        *Preliminary analyses through August 2021 show that among adults 18 years of age and older, the age-adjusted hospitalization rate was 12 times higher in unvaccinated people than those who were vaccinated. Among adults between 18-49 years of age, the rate was 14 times higher. And among adults 65 years and older, the rate was 9 times higher.

        Note to readers: COVID-19 vaccines are effective and are a critical tool to bring the pandemic under control. However, no vaccine is 100% effective at preventing illness and some “breakthrough infections” resulting in hospitalizations are expected among people who are fully vaccinated. Based on data from COVID-NET, of COVID-19-associated hospital admissions from January–August 2021, 7% were fully vaccinated; in August 2021, 21% were fully vaccinated. The proportion of patients hospitalized with COVID-19 who are fully vaccinated is expected to increase as more people get vaccinated even though these vaccines are highly effective against hospitalization and death.

          Interpretive Summary for October 29, 2021
          Give Me a Boost!


          COVID-19 cases, hospitalizations, and deaths continue to decline, but many parts of the country are still experiencing high levels of community transmission. CDC’s COVID Data Tracker shows that, as of October 28, 2021, 221 million people in the United States have received at least one dose of a COVID-19 vaccine. 191 million people are fully vaccinated. More than 15 million people have received a COVID-19 vaccine booster dose.*

          Last week, the U.S. Food and Drug Administration (FDA)external icon expanded the use of a COVID-19 vaccine booster dose for certain people. CDC now recommends that everyone 18 years and older who received the Johnson & Johnson/Janssen COVID-19 vaccine two or more months ago receive a booster dose. For people who received a Pfizer-BioNTech or Moderna COVID-19 vaccine, certain groups are now eligible for a booster dose at 6 months or more after their initial 2-dose series. This includes people ages 65 years and older, and people ages 18 years and older who live in long-term care settings, have underlying medical conditions, or live or work in high-risk settings.

          Vaccination remains the best way to protect yourself. CDC’s COVID Data Tracker shows that in August 2021, people who were unvaccinated were 11 times more likely to die from COVID-19 than people who were fully vaccinated. People who were unvaccinated were 12 times more likely to be hospitalized with COVID-19 compared to people who were fully vaccinated. Everyone should get vaccinated against COVID-19 as soon as they are eligible, including people who have already had COVID-19. To find a vaccine provider near you, visit vaccines.gov or your state or local public health department website.

          *The count of people who received a booster dose includes anyone who is fully vaccinated who has received another dose of COVID-19 vaccine since August 13, 2021. This includes people who received booster doses and people who received additional doses.

          Note to readers: People who are eligible for a COVID-19 vaccine booster dose may choose which vaccine they receive as a booster dose. Some people may prefer the vaccine type that they originally received, and others may prefer to get a different booster. CDC’s recommendations now allow for this type of mix and match dosing for booster shots

          COVID-NET: Trends in Hospitalizations of Non-Hispanic Black People


          CDC’s Coronavirus Disease 2019-Associated Hospitalization Surveillance Network (COVID-NET) shows that since the start of the pandemic, people from racial and ethnic minority groups have experienced disproportionately higher rates of COVID-19-associated hospitalizations compared to non-Hispanic White people. While rates of hospitalizations have started to decrease in all racial and ethnic groups, the hospitalization rate for non-Hispanic Black people remains higher than other groups. For the week ending October 9, 2021, preliminary data not adjusted for age show rates of COVID-19-associated hospitalizations in non-Hispanic Black people were 9.8 per 100,000 population—17% higher than rates in non-Hispanic White people (8.4 per 100,000).

              Interpretive Summary for November 5, 2021
              This is Their Shot


              Last week, the U.S. Food and Drug Administration (FDA)external icon authorized the use of the Pfizer-BioNTech COVID-19 vaccine for children ages 5 through 11 years. CDC now recommends that children ages 5 through 11 get a COVID-19 vaccine. There are approximately 28 million children in this age group in the United States, with nearly 2 million cases of COVID-19 since the start of the pandemic. While fewer COVID-19 cases and hospitalizations have been reported in children compared with adults, children can be hospitalized or die from the virus.

              Vaccinating children ages 5 through 11 is critical to preventing infections and possible severe disease. The COVID-19 vaccines being used in the United States are safe and effective. They have undergone – and will continue to undergo – the most intensive safety monitoring in U.S. history. The Pfizer-BioNTech COVID-19 vaccine for children is different than the vaccine that is given to adolescents and adults.* Children ages 5 through 11 will still require two doses three weeks apart to be considered fully vaccinated. Children may have some side effects from COVID-19 vaccination, which are normal signs that their body is building protection.

              The Pfizer COVID-19 vaccine is over 90% effective at preventing COVID-19 in children ages 5 to 11 years. Getting your child vaccinated can help protect them against COVID-19, as well as reduce disruptions to in-person learning and activities by helping to reduce the spread of COVID-19. Vaccines can also help keep your child from getting seriously sick even if they do get COVID-19. If you have questions about COVID-19 vaccines in children, talk with your child’s pediatrician or healthcare provider.

              *Children 5 through 11 years old will receive a separate vaccine formulation of the Pfizer-BioNTech COVID-19 vaccine that has one-third the dose given to adolescents and adults, and they will receive the vaccine with a smaller needle.

              Note to readers: Starting the week of November 8th, vaccines will be available at pediatricians’ offices, pharmacies, Federally Qualified Health Centers, and more. To find vaccine near you, visit vaccines.gov; text your ZIP code to 438829 (GETVAX); or call 1-800-232-0233.

                Interpretive Summary for November 19, 2021
                Protecting Our Future


                COVID-19 tends to be milder in children compared with adults, but it can make children very sick and lead to hospitalization or even death. To further protect children, those ages 5 years and older are now eligible to get an age-appropriate dose of Pfizer-BioNTech COVID-19 vaccine. Vaccinating children is also a crucial step toward stopping the spread of the virus that causes COVID-19 and ending the pandemic.

                This week CDC’s COVID Data Tracker shows that rates of COVID-19 hospitalizations remain high in children between the ages of 5 through 11 years. A recent studyexternal icon of more than 2,000 children under 18 years found that nearly 1 in 3 children hospitalized with COVID-19 were admitted to the intensive care unit or put on a ventilator. Although children with underlying medical conditions are at increased risk for more severe illness from COVID-19, almost half (45%) of the hospitalized children in this study had no known underlying medical conditions. These results show that children can be severely affected by COVID-19.

                Widespread vaccination for COVID-19 remains a critical tool to best protect everyone, especially those at highest risk, from severe illness and death. CDC recommends everyone ages 5 years and older get a COVID-19 vaccine to help protect against COVID-19. Vaccinating children ages 5 years and older can help keep them in school and safely participate in sports, playdates, and other group activities. Vaccinating children can also help protect family members, including siblings who are not eligible for vaccination and family members who may be at increased risk of getting very sick if they are infected. COVID-19 vaccines for children ages 5 through 11 years are now available at pediatricians’ offices, pharmacies, Federally Qualified Health Centers, and more. To find a vaccination site near you, visit vaccines.gov; text your ZIP code to 438829 (GETVAX); or call 1-800-232-0233. If you have questions about COVID-19 vaccines in children, talk with your child’s pediatrician or healthcare provider.

                Note to readers: In observance of the Thanksgiving holiday, CDC will not publish the COVID Data Tracker Weekly Review on Friday, November 26, 2021. The Weekly Review will resume publication on Friday, December 3, 2021.

                CDC’s Coronavirus Disease 2019-Associated Hospitalization Surveillance Network (COVID-NET) shows that having certain medical conditions can increase the risk of becoming severely ill due to COVID-19. Data from March 1, 2020 through September 30, 2021, show that 54% of children and adolescents ages 17 years and younger with a laboratory-confirmed COVID-19-associated hospitalization have at least one underlying medical condition. Among children with a COVID-19-associated hospitalization, the most common underlying medical conditions include obesity (36%), asthma (15%), neurologic disease (14%), and cardiovascular disease (9%).

                    Interpretive Summary for December 3, 2021
                    Baby Talk


                    As of December 2, 2021, more than 234 million people in the United States have received at least one dose of a COVID-19 vaccine. However, vaccination among pregnant people remains low. CDC’s COVID Data Tracker shows that as of November 27, 2021, the proportion of fully vaccinated pregnant people has increased to 35%, but most pregnant people remain unprotected against COVID-19. CDC recommends that people who are pregnant, breastfeeding, trying to get pregnant now, or who might become pregnant in the future, get vaccinated against COVID-19. CDC also recommends that fully vaccinated pregnant people 18 years and older receive a COVID-19 booster dose.

                    People who are pregnant or were recently pregnant are at increased risk for severe illness from COVID-19, including ICU admission, ventilator use, and death. A recent studyexternal icon found that for pregnant people with COVID-19 after Delta became predominant, the risk of ICU admission was 66% higher than before Delta became predominant. The risk of needing a ventilator or special equipment to breathe was 63% higher, and the risk of death was more than 2 times higher than in the pre-Delta period.* A second study found that compared with people without a COVID-19 diagnosis at delivery, pregnant people with a COVID-19 diagnosis at delivery had nearly twice the risk of having a stillbirth.** After Delta become predominant, women with COVID-19 during pregnancy had 4 times the risk of having a stillbirth.

                    Getting a COVID-19 vaccine can prevent severe illness, death, and pregnancy complications related to COVID-19. CDC data show that COVID-19 vaccines are safe for people who are pregnant, including those early in pregnancy. Additionally, there is currently no evidence that any vaccines, including COVID-19 vaccines, cause fertility problems in women or men. Many people have become pregnant after receiving a COVID-19 vaccine, including some who got vaccinated during COVID-19 vaccine clinical trials. If you have questions about getting vaccinated, talk with your healthcare provider. To find a vaccine provider near you, visit vaccines.gov; text your ZIP code to 438829 (GETVAX); or call 1-800-232-0233.

                    *The risk for severe illness also increased for non-pregnant women of reproductive age (15─44 years) with COVID-19 during the Delta period, compared with the pre-Delta period.

                    **COVID-19 diagnosis may have represented a current or past infection.

                    Note to readers: CDC’s COVID Data Tracker now features a Pregnancy Data page which catalogs all pregnancy-related data available on COVID Data Tracker and provides links to resource on COVID-19 in pregnancy. Resources and tools are available to help people who are pregnant, breastfeeding, and new parents caring for infants protect their health.

                    Reported Cases


                    The current 7-day moving average of daily new cases (86,413) decreased 8.5% compared with the previous 7-day moving average (94,393). A total of 48,628,787 COVID-19 cases have been reported as of December 1, 2021.

                    On November 26, 2021, the World Health Organization (WHO) classified a new variant, B.1.1.529, as a Variant of Concern (VOC) and named it Omicron. On November 30, 2021, the United States also classified it as a VOC. On December 1, 2021, CDC announced that the first confirmed case of Omicron variant had been detected in the United States. Additional suspected cases of Omicron are being investigated. Despite the detection of Omicron, Delta remains the predominant strain in the United States. Nowcast projections* for the week ending November 27, 2021, estimate the national and regional proportions of Delta to be greater than 99%.

                    CDC has been actively monitoring and preparing for this variant and will continue to work with other U.S. and global public health and industry partners to learn more. For more information on variant proportions, visit COVID Data Tracker.

                    CDC’s Coronavirus Disease 2019-Associated Hospitalization Surveillance Network (COVID-NET) shows that since the start of the pandemic, people from racial and ethnic minority groups have been at increased risk for COVID-19-associated hospitalizations compared to non-Hispanic White people. For the week ending November 13, 2021, the rate of COVID-19-associated hospitalizations in non-Hispanic American Indian/Alaska Native people was 23 per 100,000 people. This is the highest hospitalization rate among all racial and ethnic minority groups and represents a substantial increase over the past three months.*

                    * It is important to note that these increases might be driven by a limited number of COVID-NET sites and might not be nationally representative.

                        Get Boosted!


                        On November 26, 2021, the World Health Organizationexternal icon (WHO) classified a new variant, B.1.1.529, as a Variant of Concern (VOC) and named it Omicron. On November 30, 2021, the United States also classified it as a VOC. On December 1, 2021, CDC announced that the first confirmed case of the Omicron variant had been detected in the United States. As of December 9, 2021, 23 states have announced cases of the Omicron variant.

                        A new CDC report summarizes what’s known about initial cases of COVID-19 infection with the Omicron variant in the United States and prevention strategies to slow the spread. While Omicron viruses have been detected, the Delta variant still currently accounts for over 99.9% of all circulating SARS-CoV-2 viruses in the United States.COVID-19 vaccination, along with consistent use of prevention strategies, remains the best tool we have to protect people from COVID-19, slow transmission, and reduce the likelihood of new variants emerging. CDC recommends that:
                        As the weather gets colder and people gather indoors, getting a COVID-19 vaccine or booster dose can help protect you, the people around you, and the people you love. To find a COVID-19 vaccine provider near you, visit vaccines.gov or your state or local public health department website.

                        *Immunocompromised people have special considerations for vaccination, including additional primary dose and booster dose recommendations following the primary series. For more information, visit CDC’s website.

                        Note to readers: Self-testing (also known as home or over-the-counter testing) is another way to prevent the spread of COVID-19. You can self-test before an indoor gathering with people who don’t live in your household, regardless of your vaccination status or if you have symptoms.

                        What's New

                        Reported Cases


                        The current 7-day moving average of daily new cases (118,515) increased 37.3% compared with the previous 7-day moving average (86,315). A total of 49,458,520 COVID-19 cases have been reported in the United States as of December 8, 2021.

                        Currently two variants, Omicron and Delta, are classified as Variants of Concern (VOC) in the United States. CDC’s COVID Data Tracker shows that the Omicron variant currently accounts for less than 0.1% of variants circulating in the United States. Delta remains the predominant variant in the United States. Nowcast projections* for the week ending December 4, 2021, estimate the national and regional proportions of Delta to be greater than 99%.

                        CDC has been actively monitoring and preparing for the Omicron variant and will continue to work with other U.S. and global public health and industry partners to learn more. For more information on variant proportions, visit COVID Data Tracker.

                        Vaccinations


                        The U.S. COVID-19 Vaccination Program began December 14, 2020. As of December 9, 2021, 477.4 million vaccine doses have been administered. Overall, about 237.5 million people, or 71.5% of the total U.S. population, have received at least one dose of vaccine. About 200.7 million people, or 60.5% of the total U.S. population, have been fully vaccinated.* About 49.9 million additional/booster doses in fully vaccinated people have been reported. As of December 9, 2021, the 7-day average number of administered vaccine doses reported (by date of CDC report) to CDC per day was 1,855,455, a 29.9% increase from the previous week.

                        CDC’s COVID Data Tracker Vaccination Demographic Trends tab shows vaccination trends by age group. As of December 9, 2021, 95.0% of people ages 65 years or older have received at least one dose of vaccine and 87.0% are fully vaccinated. More than three-quarters (83.9%) of people ages 18 years or older have received at least one dose of vaccine and 71.8% are fully vaccinated. For people ages 12 years or older, 81.9% have received at least one dose of vaccine and 70.1% are fully vaccinated. For people ages 5 years or older, 76.0% have received at least one dose of vaccine and 64.3% are fully vaccinated.

                        CDC’s Coronavirus Disease 2019-Associated Hospitalization Surveillance Network (COVID-NET) shows that through October 2021, rates of COVID-19-associated hospitalizations are higher in unvaccinated adults compared to fully vaccinated adults regardless of age. The age-adjusted COVID-19-associated hospitalization rate among adults ages 18 years and older was 8 times higher in unvaccinated people than those who were vaccinated. Age-specific rates of COVID-19-associated hospitalizations are 13 times higher among unvaccinated adults ages 18-49 years, 11 times higher among unvaccinated adults ages 50–64 years, and 6 times higher among unvaccinated adults ages 65 years and older.

                        State of the Pandemic – Fall 2021


                        In the United States, the SARS-CoV-2 pandemic has produced 5 waves of new cases. The peaks of those waves were on April 9, 2020 (34,893 cases), July 17, 2020 (78,252 cases), January 6, 2021 (295,378 cases), April 7, 2021 (79,302 cases), and September 1, 2021 (192,211 cases). The first peak likely under-represented the true case incidence because the availability and use of testing was limited at that early point in the pandemic. The third peak, in January 2021, was the highest. The recent fifth peak, in September 2021, was more than 100,000 cases lower than the January 2021 peak. Although the burden of severe illness was high with large numbers of hospitalizations and deaths in the most recent wave, both were much lower than in the third wave. Population immunity levels, both from vaccination and from previous infection, likely limited the impact of the virus during the fifth wave.

                        Nationally, surveillance indicators tracking levels of SARS-CoV-2 circulation and associated illnesses, hospital admissions, and deaths began declining in early September 2021, and continued into October 2021. As the weather began to get colder and people started to spend more time indoors, we started to see an increase in cases and hospitalizations in November 2021. On December 8, 2021, the current 7-day moving average of new cases nationwide was 118,515, up 37.3% from the previous week. The 7-day average of new hospital admissions was 7,441, up 15.9% from the previous week. The 7-day moving average of new deaths nationwide was 1,092, up 27.8% from the previous week.

                        As of December 9, 2021, over 237 million people (71.5% of the US population) have been fully vaccinated. Older adults have the highest vaccination rates of any age group: 87.0% of people ages 65 years or older are fully vaccinated. As of December 9, 2021, 17.9% of people ages 5 through 11 years old have received at least one dose of vaccine and 7.0% of people ages 5 through 11 years old are fully vaccinated. CDC recommends that people with compromised immune systems receive an additional dose of an mRNA COVID-19 vaccine.

                        For people who received a primary series of an mRNA COVID-19 vaccine, booster doses are recommended at least six months after completing the primary series for everyone ages 18 years and older. Everyone ages 18 years and older who received the Johnson & Johnson/Janssen vaccine should get a booster shot at least two months after receiving the primary shot. On December 9, 2021, the U.S. Food and Drug Administration authorized the use of a single booster dose for adolescents ages 16 and 17 years at least six months after completion of a primary series with the Pfizer-BioNTech COVID-19 vaccine. That same day, CDC strengthened its booster dose recommendations and now encourages everyone 16 years and older to receive a booster dose. At this time, only the Pfizer-BioNTech COVID-19 vaccine is authorized and recommended for adolescents ages 16 and 17 years. Since August 2021, over 49.9 million fully vaccinated people have received a booster dose; 26.9% of those ages 18 years or older and 49.1% of those ages 65 years or older who are fully vaccinated have received a booster dose.

                        A new SARS-CoV-2 variant, named Omicron by the World Health Organization, was classified on November 30, 2021, as a Variant of Concern by the U.S. government SARS-CoV-2 Interagency Group. The first U.S. case of the Omicron variant was confirmed on December 1, 2021, and has now been detected in a number of states. CDC is working with state and local public health officials to monitor the spread of the new variant. CDC is also working with its public health partners to determine how easily the variant is transmitted, the severity of disease caused by the variant, and how well vaccines and therapeutics will work against the variant. However, the emergence of this variant and the fact that the Delta variant continues to be the most dominant variant present in the United States, reinforces the need for people to get vaccinated and for those fully vaccinated to receive boosters.

                        As the country approaches the winter—typically the high season for respiratory viruses like SARS-CoV-2 and influenza — there are many unknowns. Continuing to monitor case rates and the burden of COVID-19 illnesses and hospitalizations will be key to responding quickly and effectively in the coming months to limit illness and keep our health systems functioning for all people. COVID-19 vaccination is crucial to controlling the pandemic as it provides substantial protection against infection, hospitalization, and death. As we approach the holiday season, a time when gatherings of friends and families are common, it is important to maintain prevention measures and ensure protection of those most vulnerable.

                            Summary for December 17, 2021

                            Safe and Happy Holidays


                            The United States recently surpassed 50 million COVID-19 cases and 800,000 deaths since the start of the pandemic. This week also marks the first anniversary of the first COVID-19 vaccination in the United States. In recent weeks, COVID-19 cases and hospitalizations have increased, with many parts of the country experiencing substantial or high levels of community transmission. These increases and the recent emergence of the Omicron variant highlight the importance of prevention strategies to help people stay safe and reduce the spread of the virus that causes COVID-19.

                            Although we are still learning about Omicron, we’ve been fighting COVID-19 since last year and have the tools to end the pandemic. The United States saw the highest peak in COVID-19 cases in January 2021, following the 2020 holiday season. But this year, we have the most important protection of all: vaccination. As people start to travel and gather this year, COVID-19 vaccination, along with other important prevention strategies, continues to be our best defense against severe disease.
                            Holiday traditions are important for many people. Using proven prevention strategies, we can enjoy safer holidays, travel, and protect our own health as well as the health of our family and friends.

                            Note to readers: CDC will not publish the COVID Data Tracker Weekly Review on Friday, December 24, 2021, and Friday, December 31, 2021. The Weekly Review will resume publication on Friday, January 7, 2022.

                            What's New

                            Reported Cases


                            The current 7-day moving average of daily new cases (122,297) increased 1.5% compared with the previous 7-day moving average (120,445). A total of 50,479,372 COVID-19 cases have been reported in the United States as of December 15, 2021.

                            Currently two variants, Omicron and Delta, are classified as Variants of Concern (VOC) in the United States. CDC’s COVID Data Tracker shows that the proportion of the Omicron variant circulating in the United States is predicted to increase from last week. Delta remains the predominant variant in the United States. Nowcast projections* for the week ending December 11, 2021, predict the national proportion of Omicron to be 2.9% and Delta to be 96.7%. The proportion of Omicron is predicted to be higher than the national proportion in HHS regions 2 and 7. The proportions of Delta are predicted to be greater than 86% in all HHS regions.

                            CDC has been actively monitoring and preparing for the Omicron variant and will continue to work with other U.S. and global public health and industry partners to learn more. For more information on variant proportions, visit COVID Data Tracker.

                            The U.S. COVID-19 Vaccination Program began December 14, 2020. As of December 16, 2021, 490.0 million vaccine doses have been administered. Overall, about 240.3 million people, or 72.4% of the total U.S. population, have received at least one dose of vaccine. About 203.2 million people, or 61.2% of the total U.S. population, have been fully vaccinated.* About 57.1 million additional/booster doses in fully vaccinated people have been reported. As of December 16, 2021, the 7-day average number of administered vaccine doses reported (by date of CDC report) to CDC per day was 1,799,583, a 3.0% decrease from the previous week.

                            CDC’s COVID Data Tracker Vaccination Demographic Trends tab shows vaccination trends by age group. As of December 16, 2021, 95.0% of people ages 65 years or older have received at least one dose of vaccine and 87.3% are fully vaccinated. More than three-quarters (84.7%) of people ages 18 years or older have received at least one dose of vaccine and 72.3% are fully vaccinated. For people ages 12 years or older, 82.7% have received at least one dose of vaccine and 70.5% are fully vaccinated. For people ages 5 years or older, 76.9% have received at least one dose of vaccine and 65.1% are fully vaccinated.

                            CDC’s Coronavirus Disease 2019-Associated Hospitalization Surveillance Network (COVID-NET) shows that hospitalization rates remain elevated in young children. For the week ending November 27, the weekly rate of COVID-19-associated hospitalizations for children ages 4 years and younger is 1.9 per 100,000. The rate of hospitalization in this age group is higher than rates seen for both older children ages 5–11 years (0.4 per 100,000) and adolescents ages 12–17 years (0.9 per 100,000). Unlike older children and adolescents, children ages 4 years and younger are not yet eligible for any of the available COVID-19 vaccines.

                            Know More about the Omicron Variant


                            On November 24, 2021, a new variant of SARS-CoV-2, B.1.1.529, was reported to the World Health Organizationexternal icon (WHO). This new variant was first detected in specimens collected on November 11, 2021, in Botswana and on November 14, 2021, in South Africa. On November 26, 2021, WHO named the variant Omicron and classified it as a Variant of Concern (VOC). Four days later, on November 30, the U.S. government SARS-CoV-2 Interagency Group also designated Omicron as a VOC. On December 1, 2021, the first confirmed U.S. case of Omicron was identified in California. As of December 15, 2021, 70 countries have verified SARS-CoV-2 infections caused by the Omicron variant.

                            CDC has been working with state and local public health officials to monitor the spread of Omicron in the United States. Multiple states have now detected Omicron cases. On December 10, 2021, CDC released an MMWR article summarizing characteristics of the first infections in the United States with the Omicron variant, along with prevention strategies to slow the spread.

                            In the United States, CDC uses genomic surveillance to track variants of SARS-CoV-2. CDC’s national genomic surveillance can detect a variant that is circulating at 0.1% frequency with 99% statistical confidence. There is a two- to three-week lag between sample collection for SARS-CoV-2 testing to producing and analyzing sequence data, so it is likely that more U.S. infections with Omicron from late November will be detected over the coming days. To provide more timely estimates of variant proportions while more recent specimens are being processed, CDC also provides “Nowcast” data. Nowcast is a model that estimates more recent proportions of circulating variants and enables timely public health action. CDC’s genomic surveillance system will continuously monitor the proportion of infections from Omicron and other variants.

                            The Omicron variant contains more changes in the spike protein than have been observed in other variants, including 15 in the receptor binding domain (RBD). (The spike protein is the primary target of vaccine-induced immunity.) There are also changes and deletions in other regions of the genome. Based on preliminary laboratory data, significant reductions in neutralizing activity of sera from vaccinated or previously infected individuals against Omicron have been reported. Based on data from other variants with significantly fewer changes in the RBD, the expectation is that the Omicron variant will remain susceptible to some monoclonal antibody treatments, while others may have less potency.

                            Scientists around the world are working quickly to learn more about the Omicron variant and better understand how easily it might be spread, how severe illness is with this variant, and how effective diagnostic tests, vaccines, and therapeutics are for this variant. Preliminary information from South Africaexternal icon indicates that there are no unusual symptoms associated with Omicron variant infection, and as with other variants, some patients are asymptomatic. CDC will be prioritizing multiple studies to better understand the Omicron variant.

                            We expect current vaccines to protect against severe illness, hospitalizations, and deaths from infection with the Omicron variant. However, Omicron might cause more breakthrough infections than prior variants, though information on the extent of vaccine protection against infection is not yet available.

                            It is important to remember that despite the increased attention of Omicron, Delta continues to be the main variant circulating in the United States. For the week ending December 11, 2021, the Delta variant accounted for 96.7% of circulating SARS-CoV-2 variants and Omicron accounted for 2.9% of circulating SARS-CoV-2 variants. The recent emergence of Omicron and the fact that Delta is still the dominant strain further emphasize the importance of getting a primary vaccination series and, if eligible, a booster.

                              Resolve to be Safe


                              COVID-19 cases continue to increase rapidly across the United States. This surge is driven by the Omicron variant, which CDC’s Nowcast model projects may account for approximately 95% of cases. On January 5, 705,264 new cases were reported, more than doubling the January 2021 peak. The entire country is now experiencing high levels of community transmission. Hospitalizations are also on the rise. While early data suggest Omicron infections might be less severe than those of other variants, the increases in cases and hospitalizations are expected to stress the healthcare system in the coming weeks.

                              Given what we currently know about COVID-19 and the Omicron variant, CDC recently updated its quarantine and isolation recommendations for the public.* If you come into close contact with someone with COVID-19, you should quarantine if you are in one of the following groups:
                              If you have confirmed or suspected COVID-19, regardless of your vaccination status, stay home and isolate from other people for at least 5 full days. Wear a well-fitting mask when around others at home and in public for an additional 5 days. Testing may be used to help determine when to end your isolation period. For information about when and how to test, visit CDC’s website.

                              Vaccination remains the best way to protect yourself from COVID-19 and reduce its impact on our communities. Everyone should get vaccinated and boosted as soon as they are eligible, including people who have already had COVID-19. Find a vaccine.

                              *CDC’s updated recommendations reflect the impact to society, the latest science on disease severity, and when and for how long a person is maximally infectious. CDC will continue to evaluate these recommendations as more data become available.

                              Note to readers: You quarantine when you might have been exposed to the virus and may or may not have been infected. You isolate when you have been infected with the virus, even if you don’t have symptoms. When counting days for isolation, day 0 is the first day of symptoms. If you are asymptomatic, day 0 is the day of your positive viral test. For more information, visit CDC’s website.

                              Currently two variants, Omicron and Delta, are classified as Variants of Concern (VOC) in the United States. CDC’s COVID Data Tracker shows that the proportion of the Omicron variant circulating in the United States is predicted to increase from the week ending December 25, 2021 and is the predominant variant in the United States. Nowcast projections* for the week ending January 1, 2022, predict the national proportion of Omicron to be 95.4% (95% PI 92.9-97%) and Delta to be 4.6% (95% PI 2.9-7%). Omicron is predicted to be greater than 75% in all HHS regions.

                              CDC’s Coronavirus Disease 2019-Associated Hospitalization Surveillance Network (COVID-NET) shows that hospitalization rates remain elevated in young children. For the week ending December 18, the weekly rate of COVID-19-associated hospitalizations for children ages 4 years and younger is 2.5 per 100,000. The rate of hospitalization in this age group is higher than rates seen for both older children ages 5–11 years (0.5 per 100,000) and adolescents ages 12–17 years (1.5 per 100,000). Unlike older children and adolescents, children ages 4 years and younger are not yet eligible for any of the available COVID-19 vaccines.

                              A Closer Look: Update on the Omicron Variant


                              Since identifying the first case of the Omicron variant in the United States on December 1, 2021, CDC has been working with state, tribal, local, and territorial public health officials to monitor the spread of Omicron in the United States. On December 10, 2021, CDC released an MMWR article summarizing characteristics of the first Omicron infections in the country. CDC has also identified a rapid increase in infections consistent with what has been observed in other countries. Increases in infections are most likely due to a combination of two factors: increased transmissibility and immune evasion (the ability of the variant to evade immunity conferred by past infection or vaccination). Though the precise contribution of each of the two factors remains unknown, a substantial degree of immune evasion is likely as has been demonstrated in early in vitro studies.

                              CDC uses genomic surveillance to track variants of SARS-CoV-2 in the United States. CDC’s national genomic surveillance can detect a variant that is circulating at 0.1% frequency with 99% statistical confidence. Current-week estimates of variant proportions are provided by CDC’s Nowcast modeling data, enabling timely public health action while specimens are undergoing the two- to three-week sequencing and analysis process. As of the week ending December 25, 2021, Nowcast estimated that Omicron accounted for 95.4% of circulating SARS-CoV-2 strains while Delta accounted for 4.6% of circulating strains.

                              The clinical severity profile of Omicron infection will strongly influence its impact on U.S. hospitalizations and deaths. A study from South Africaexternal icon demonstrates that in the first four weeks of the Omicron variant wave there were lower rates of hospitalization compared to the first four weeks of the Beta- or Delta-dominated waves in Gauteng Province. There was also less severe illness reported for those that were admitted. A study conducted in Canadaexternal icon found that the risk of hospitalization was 54% lower for Omicron cases compared with Delta cases.

                              Even if the proportion of infections associated with severe outcomes is lower than with previous variants, the absolute numbers of people with severe outcomes could be substantial given the rapid increase in the number of infections over the past three weeks. In addition, demand for ambulatory care and supportive care for treatment of mild cases could also stress the healthcare system. Geographical differences in the predominance of the Omicron variant versus ongoing Delta variant infections and the rising burden of illness caused by other respiratory pathogens, such as influenza, may stress healthcare systems regionally to various degrees. On December 23, 2021, CDC issued updated guidance to enhance protection for healthcare personnel, patients, and visitors to address concerns about potential impacts on the healthcare system given a surge of SARS-CoV-2 infections. On January 4, 2022, CDC also issued updated guidance on quarantine and isolation for the public.

                              Some studies have demonstrated the importance of booster doses in protecting against infection with Omicron, and a lower effectiveness of the primary series of vaccines alone. Current CDC recommendations for vaccines and booster shots are expected to protect against severe illness, hospitalizations, and deaths from infection with the Omicron variant. Therapeutics, including monoclonal antibody treatments and antivirals, are also available for preventing and treating COVID-19 in specific at-risk populations. These therapeutics differ in efficacy, route of administration, risk profile, and whether they are authorized by the U.S Food and Drug Administrationexternal icon for adults only or adults and certain pediatric populations. Some therapeutics are in relatively short supply, but availability is expected to increase in the coming months. Current recommendations were summarized in a CDC Health Alert Network Health Advisory, Using Therapeutics to Prevent and Treat COVID-19, published December 31, 2021.

                              Scientists around the world, including researchers at CDC, are working quickly to learn more about the Omicron variant. The recent emergence of Omicron and the fact that Delta is still a circulating variant further emphasize the importance of getting a primary vaccination series and, if eligible, a booster and continuing prevention measures.
