Flu vaccination prevents millions of flu-related illnesses and deaths annually, but vaccination rates are low for many reasons.
During the 2018-2019 flu season, the Centers for Disease Control and Prevention reported that about 45% of U.S. adults received the flu vaccine. While this is an increase of 8% from 2017-2018, it falls way below the national goal of 70% of American adults receiving a flu shot.
One of the common myths that leads people to avoid the flu shot is that they think the shot will give them the flu. But that is simply not true. The virus in the vaccine is not active, and an inactive virus cannot transmit disease. What is true is that you may feel the effects of your body mounting an immune response, but that does not mean you have the flu.
