COVID-19 vaccines protect against severe illness, hospitalization and death by teaching our bodies how to fight the virus. A safe, effective, free COVID-19 vaccine is available to everyone ages 6 months and older. A booster dose is recommended for everyone ages 5 years and older for added protection. People at higher risk, including people ages 50 years and older, should get a second booster dose.
