A new cross-sectional study published in Vaccine of US adults demonstrates that people who received the COVID-19 booster vaccine had 25% lower odds of having long COVID than their unvaccinated counterparts.
The study was based on 8,757 respondents to the 2022 National Health Interview Survey, with data from a weighted sample size of 87,509,670 Americans. Authors used self-reported COVID-19 booster vaccination status and self-reported long-COVID status (defined as having new or persistent symptoms 3 or more months after an initial COVID-19 infection) to calculate odds ratios (ORs) of developing long COVID.
1 in 5 report long COVID
Overall, 2.2% (19,396,656) had not received any COVID-19 vaccine, 17.3% (15,151,843) had received only one dose of the COVID-19 vaccine, 33.3% (29,184,366) had completed the initial series of the COVID-19 vaccine, and 27.2% (23,776,806) received the COVID-19 booster vaccine. Among all respondents, 19.5 % reported experiencing long COVID (17,102,276).
People receiving the COVID-19 booster vaccine had significantly lower adjusted odds of long COVID (OR 0.75, 95 % confidence interval 0.61 to 0.93) compared to unvaccinated people.
"Our findings suggest that ensuring individuals are up-to-date with their COVID-19 vaccinations could be an effective public health strategy for reducing the prevalence of long-COVID," the authors concluded.
After COVID vaccine rollout, negativity on Twitter spiked

Negativity about vaccines surged 27% on Twitter after COVID-19 vaccines first became available, according to a new study presented this week at the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) Global Congress.
In the years prior to COVID-19, there were more negative statements about vaccines than positive ones, but the introduction of vaccines and news about mandating vaccines caused negative statements to spike on Twitter, now called X.
The study used data from an open-source software (the Snscrape library in Python). The program downloaded tweets with the hashtag "vaccine" published on Twitter from January 1, 2018, to December 31, 2022.
A total of 567,915 tweets were extracted and analyzed, with 458,045 classified as negative and 109,870 as positive by a machine-learning algorithm. After the introduction of COVID-19 vaccines at the end of 2020, there was an average 10,201 more vaccine-related Tweets per month.
Negative tweets peaked in April 2021
The program identified 310,508 tweets (12,420 a month on average) with negative sentiment after December 11, 2020. This represents a 27% increase in negative tweets than would be expected had the COVID-19 vaccines not been introduced (9,785 a month, 95% confidence interval, 9,282 to 10,249).
April 2021, the month the White House announced that all people aged 16 and older would be eligible for the COVID-19, had the highest number of negative tweets.
"Vaccines can prevent complications from diseases for which we have limited treatment options, such as influenza and COVID-19, but there has been growing opposition to their use in recent years," said first study author Guillermo Rodriguez-Nava, MD, of Stanford University, in an ESCMID press release.
The damage caused by negative voices is already apparent.
"The damage caused by negative voices is already apparent, with clusters of measles re-emerging in countries where it was previously considered eradicated."
Undocumented Latinos vaccinated against COVID at same rate as US citizens, study suggests

COVID-19
A University of California at Los Angeles (UCLA) study late last week in JAMA Network Open finds that, despite less access to healthcare, undocumented Latino workers who visited the emergency department (ED) received COVID-19 vaccines at the same rate as US citizens.
The researchers interviewed a sample of adult non-Latino patients, legal Latino residents or citizens, and undocumented Latino patients at two California healthcare centers from September 2021 to March 2022.
The median age of the 306 participants was 51 years, 48% were women, 68% were Latino, 14% were White, 11% were Black, and 7% were of other race. Of undocumented Latinos, 25% were uninsured, and 30% usually visited the ED for healthcare.
Undocumented workers much more likely to report infection
Among all participants, 87% said they had received one or more doses of COVID-19 vaccine, and 13% reported declining the vaccine. Concern about potential adverse effects of the vaccine was the most common reason (37%) for not getting vaccinated.
Undocumented Latino workers were much more likely to report a previous COVID-19 infection than non-Latinos and legal Latino residents.
Relative to undocumented Latinos, non-Latino patients were much less likely to believe that undocumented workers could receive the COVID-19 vaccine in the United States (odds ratio [OR], 0.09). Thirteen percent of interviewees said they knew undocumented people who didn't get vaccinated because they worried about deportation. Of those who had declined the vaccine, 22% said they were interested in receiving a dose in the ED.
Undocumented Latino workers were much more likely to report a previous COVID-19 infection than non-Latinos (OR, 3.42) and legal Latino residents (OR, 2.73).
"We would have expected Latinx patients to have lower rates of vaccination, considering higher rates of infection, hospitalizations, and death," lead author Jesus Torres, MD, MPH, said in a UCLA news release. Torres noted that EDs are one of the main healthcare access points for undocumented workers, who make up about 3% of the US population but are not often included in research.
From a public health perspective, he added, it's important to identify disadvantaged groups for research, policy work, resource allocation, and targeted vaccine campaigns.
