Flu Shot Likely Prevented 13 Million Illnesses, 110,000 Hospitalizations From 2005-2011
Influenza vaccine reduced disease outcomes by up to 18.5 percent, study estimates
Approximately 13 million illnesses and over 110,00 hospitalizations may have been averted by the flu vaccine over the last 6 years in the U.S, according to calculations published June 19 in the open access journal PLOS ONE by Deliana Kostova and colleagues from the U.S Centers for Disease Control and Prevention.
The U.S is the only country with universal influenza vaccine recommendations that suggest everyone aged 6 months and older should receive an annual dose of the vaccine. However, previous studies have not provided ways to reliably assess the number of flu cases or hospitalizations that are prevented by vaccination each year. Senior author on the study Joseph Bresee adds, ""These results confirm the value of influenza vaccination, but highlight the need for more people to get vaccinated and the imperative for vaccines with greater efficacy, especially in the elderly".
