Interim results: influenza A (H1N1) 2009 monovalent vaccination coverage --- United States, October-December 2009.

Centers for Disease Control and Prevention (CDC).

In July 2009, the Advisory Committee on Immunization Practices (ACIP) issued recommendations for use of the influenza A (H1N1) 2009 monovalent vaccine. Recognizing that the vaccine supply would not be ample immediately but would grow over time, ACIP identified 1) initial target groups, consisting of approximately 160 million persons, and 2) a limited vaccine subset of the target groups, initially estimated at 42 million persons (and more recently estimated at 62 million persons), to receive first priority while the 2009 H1N1 vaccine supply was limited. ACIP recommended expanding vaccination to the rest of the population as vaccine supplies increased. To estimate 2009 H1N1 vaccination coverage to date for the 2009--10 influenza season, CDC analyzed results from the National 2009 H1N1 Flu Survey (NHFS) and the Behavioral Risk Factor Surveillance System (BRFSS) survey, conducted during December 27, 2009-January 2, 2010, and December 1-27, 2009, respectively. The results indicated that, as of January 2, an estimated 20.3% of the U.S. population (61 million persons) had been vaccinated, including 27.9% of persons in the initial target groups and 37.5% of those in the limited vaccine subset. An estimated 29.4% of U.S. children aged 6 months--18 years had been vaccinated. Now that an ample supply of 2009 H1N1 vaccine is available, efforts should continue to increase vaccination coverage among persons in the initial target groups and to offer vaccination to the rest of the U.S. population, including those aged >or=65 years.

Influenza A (H1N1) 2009 Monovalent Vaccination Coverage -- US, Oct-Dec 2009: Editorial Note


The results in this report show that nearly 90% of adults aged < 65 years with medical conditions that increase their risk for influenza-related complications remain unvaccinated. Among adults hospitalized with 2009 H1N1 infection, approximately three fourths had at least one high-risk condition (e.g., asthma, chronic obstructive pulmonary disease, diabetes and chronic cardiovascular disease).[9] Given the increased supply of vaccine, efforts to encourage 2009 H1N1 vaccination among persons at increased risk for 2009 H1N1 influenza complications should be strengthened.

Seasonal influenza vaccination coverage among health-care workers historically has been below 50%.[8] Efforts to vaccinate health-care workers began when 2009 H1N1 vaccine first became available, but according to the BRFSS survey, during December 1-27, only 22% of health-care workers reported having been vaccinated. Unvaccinated health-care workers who become infected risk transmitting the virus to their family members or patients, who often are at high risk for severe influenza. The current high percentage of unvaccinated health-care workers highlights the need to strengthen measures to improve their influenza vaccination coverage.
