Home > Health Library > Vaccines to Prevent the Flu
You can help prevent the flu by getting a flu vaccine every year, as soon as it is available. You cannot get the flu from the vaccine. The vaccine prevents most cases of the flu. But even when the vaccine doesn't prevent the flu, it can make symptoms less severe and reduce the chance of problems from the flu.
Everyone age 6 months or older should get a flu vaccine each year. It lowers the chance of getting and spreading the flu. The vaccine is very important for people who are at high risk for getting other health problems from the flu. This includes:
Flu vaccines are made to work against more than one strain of flu. For example, a trivalent vaccine works against three strains, and a quadrivalent vaccine works against four strains of flu. The U.S. Centers for Disease Control and Prevention (CDC) does not recommend one version over another version.
Flu viruses are always changing. Each year's flu vaccine is made to protect against viruses that are likely to cause disease that year. Ask your doctor whether or not a vaccine is safe for you and which one may be best for you.
