Staying up to date on vaccines, including boosters, is the most effective way to protect yourself from serious illness, hospitalization, or death from COVID-19. New updated COVID-19 booster vaccines were recently authorized by the FDA and recommended by the CDC. Boosters restimulate the immune system and increase vaccine efficacy again. Boosters are an important defense, even if you’ve already had COVID-19.
