Although COVID-19 vaccines remain effective in preventing severe disease, recent data suggest their effectiveness at preventing infection or severe illness wanes over time, especially in people ages 65 years and older. The recent emergence of the Omicron variant further emphasizes the importance of vaccination, boosters, and prevention efforts needed to protect against COVID-19. To be optimally protected, a person needs to get a booster shot when and if eligible.
The COVID-19 vaccinations are available at local pharmacies, pop-up clinics, and other events.
