Why do elderly people with underlying medical conditions need a flu shot?

Influenza vaccines not only help prevent influenza virus infection, but also contribute to a significant reduction in the risk of hospitalization and death in the elderly, with underlying medical conditions.

Experts said that each year the health system will announce a new flu vaccine for that year.

People who received the flu vaccine last year should still get a new vaccine this year.

Antibody levels produced when getting the flu vaccine have been studied safely, so people don’t need to worry about distance if the timing of the shot is close.

The flu vaccine only contains part of the coat of the flu virus, so it is still effective against influenza with few side effects.
