Question

the influenza virus can evolve or mutate. the influenza vaccine works by using an immune response with certain strains of influenza virus that are in the vaccine. Early fall is the best time to get vaccinated against the flu. Depending on how closely the vaccination matches the virus types that are around the flu vaccine changes every year. The vaccination might be on average, from 40% to 60%. With very few exceptions, practically everyone 6 months of age and older should get the flu shot. The vaccine is not indicated for some people, such as those who have had bad responses to older flu shots. Every year, the CDC revises its advice on being vaccinated against the flu in order to take into account how the virus changes and to make sure the vaccine is effective against the strains that are most likely to be alive at the time.

Answer 1

The flu virus can change and the flu shot helps your body fight against certain types of the flu virus. It's recommended to get vaccinated in early fall. The flu shot is different every year because it needs to match the virus that's going around. On average, the flu shot is about 40% to 60% effective. Almost everyone aged 6 months and older should get the flu shot, with a few exceptions for people who had a bad reaction to previous flu shots. The CDC updates their advice each year to make sure the vaccine works against the most common flu strains at that time.
