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.
In the United States, flu is most common in the wintertime and peaks between December and March. The flu vaccine is the single best way to prevent the flu. A flu shot is recommended every year because your bodyâs resistance to flu virus diminishes and the flu virus can change from season to season. A flu shot can take up to two weeks to reach maximum potency, which is why itâs recommended early in the flu season. Influenza can be spread to others up to 24 hours before a person develops symptoms and up to seven days after becoming sick.
