What are the new updates for the flu vaccine in 2021?
First, let’s get an old myth out of the way. Receiving a flu shot will not give you the flu. The virus in your shot is not live, and has been weakened to the point that it will not actually get you sick, but will encourage your body to start creating antibodies to fight a possible flu. That being said, let’s talk about which one will be right for you. There are many different types of flu vaccines, and the determining factors for which one you should get mostly come down to your age, and current state of health. Regardless, the flu shot is either going to be trivalent, meaning it protects against three strains of the virus, or quadrivalent, meaning it protects against four. AFC Urgent Care Dedham offers the quadrivalent flu vaccine. There have been updates to the vaccines to better combat possible strains in the 2021/2022 flu season.
