The 2023–2024 updated COVID-19 vaccines from Pfizer-BioNTech, Moderna, or Novavax, are recommended to protect against serious illness from COVID-19.
COVID-19 vaccines available in the Unites States are effective at protecting people from severe illness, hospitalization, and death. As with other vaccines, you are protected best from COVID-19 when you stay up to date with the recommended vaccinations.
The virus continues to evolve and protection against it from previous vaccination decreases over time. Getting a COVID-19 vaccine is a safer, more reliable way to build protection than getting sick with COVID-19. COVID-19 vaccines can also offer added protection to people who had COVID-19, including protection against being hospitalized from a new infection.
COVID-19 vaccine recommendations may be updated as CDC continues to monitor the latest COVID-19 data.
