Press Release

New Report Highlights Benefits of Flu Vaccine

During National Influenza Vaccination Week, CDC urges unvaccinated Americans to get a flu vaccine

Flu vaccination prevented an estimated 6.6 million influenza-associated illnesses, 3.2 million medically attended illnesses, and 79,000 hospitalizations during the 2012-2013 flu season, according to a Centers for Disease Control and Prevention (CDC) report in the Morbidity and Mortality Weekly Report (MMWR). CDC also reported today that despite the benefits of flu vaccination, only 40% of Americans 6 months and older had reported getting a flu vaccine this season as of early November 2013.

The estimated benefits of vaccination for the 2012-2013 season are higher than any other season for which CDC has produced similar estimates. These high numbers are attributable to the severity of the season. The report estimates that last season there were a total of 31.8 million influenza-associated illnesses, 14.4 medically attended illnesses, and 381,000 hospitalizations in the United States.
“The estimated number of hospitalizations reinforces what we have always known about flu: that it is highly variable and can be very serious,” said CDC Director Tom Frieden, M.D., M.P.H.

Children aged 6 months through four years and persons aged 65 and older, who are among those most vulnerable to influenza, accounted for an estimated 69% of prevented hospitalizations.

CDC often cites flu as being responsible for 200,000 hospitalizations each season. This average is taken from data during the 1990s, when annual estimates ranges from 158,000 hospitalizations in 1990-1991 to a high of 431,000 hospitalizations in 1997-1998.

“Most of estimated hospitalizations last season were in people 65 and older. This shows how hard a severe H3N2 season can hit this vulnerable group,” Dr. Frieden said.
