COVID-19 Vaccines

COVID-19 vaccines available in the United States are effective at protecting people from getting seriously ill, being hospitalized, and dying.

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.

As with other vaccines, you are protected best from COVID-19 when you stay up to date with the recommended vaccinations, including recommended boosters, when you are eligible.

COVID-19 vaccine and booster recommendations may be updated as CDC continues to monitor the latest COVID-19 data.

Recommendation for Everyone Aged 6 Years and Older

  • Everyone 6 years and older should get 1 updated Pfizer-BioNTech or Moderna COVID-19 vaccine.
  • People 65 years and older may get a 2nd updated Pfizer-BioNTech or Moderna COVID-19 booster dose at least 4 months after the initial bivalent dose. 
  • People who are moderately or severely immunocompromised may get additional updated Pfizer-BioNTech or Moderna COVID-19 booster doses at least 2 months after the initial bivalent dose. Additional doses may be administered for people who are at higher risk conditions at the discretion of your healthcare provider. 
  • Children 6 months–5 years may need multiple doses of COVID-19 vaccine to be up to date. This includes at least 1 updated dose of Pfizer-BioNTech or Moderna COVID-19 vaccine, depending on the number of doses they’ve previously received and their age. See recommendations for children 6 months—5 years.

Updated COVID-19 Vaccines

Updated, or bivalent, COVID-19 boosters can help restore protection that has decreased since your previous vaccination and provide broader protection against newer variants. The updated boosters target both the original virus and more recent Omicron subvariants, BA.4 and BA.5, that are more contagious and more resistant than earlier strains of the virus.

Previous COVID-19 vaccines are called original, or monovalent, because they were designed to protect against the original virus that causes COVID-19. The original monovalent Moderna and Pfizer-BioNTech COVID-19 vaccines are no longer authorized for use in the U.S. 

Guidance for People Who are Immunocompromised

If you are moderately or severely immunocompromised (have a weakened immune system), you are at increased risk of severe COVID-19 illness and death. Additionally, your immune response to COVID-19 vaccination may not be as strong as in people who are not immunocompromised. 

People who are moderately or severely immunocompromised have different recommendations for COVID-19 vaccines.
