For years, the CDC has been promoting the notion that flu shots are between 70 and 90 percent effective in preventing influenza 16 and everybody needs to get vaccinated because type A and type B influenza causes more than 200,000 hospitalizations and 36,000 deaths in the U.S. every year.
Vaccine effectiveness is the percent reduction in the frequency of influenza illness among vaccinated people compared to people not vaccinated, usually with adjustment for factors (like presence of chronic medical conditions) that are related to both influenza illness and vaccination.
