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.
It takes about two weeks to develop immunity to the flu, and experts recommend getting vaccinated before flu season is in full swing to ensure adequate protection. Even getting a flu shot as late as January can help protect against the flu, particularly if the season peaks in February or March.
