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.
By contrast, getting the flu shot reduced the risk of visiting the doctor for flu by about 50 to 60 percent in people from other age groups. Nevertheless, older people are still advised to get a flu shot, the CDC says. The vaccine's effectiveness can vary from season to season, and person to person.
