Vaccination is the best protection against the COVID-19 virus. We are still learning about the length of time both natural immunity (immunity the body develops after an illness) and vaccine-induced immunity for COVID-19 will last.  

People are protected best from COVID-19 when they stay up to date with their COVID-19 vaccines, which includes getting all recommended boosters when eligible. Millions of people age 5 and older are eligible to receive a booster shot and will benefit from additional protection. To get the best protection against COVID-19, especially against severe illness and hospitalization, stay up to date on your COVID-19 vaccines.

See additional recommendations for people who are moderately to severely immunocompromised. The recommended vaccination schedule from the Centers for Disease Control and Prevention is available here.
