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

CDC recommends everyone stay up to date with COVID-19 vaccination, including all primary series doses and bivalent boosters for their age group.

Updated Boosters Are Recommended

  • CDC recommends one updated (bivalent) booster dose:
  • The updated (bivalent) boosters are called “bivalent” because they protect against both the original virus that causes COVID-19 and the Omicron variant BA.4 and BA.5.
  • Previous boosters are called “monovalent” because they were designed to protect against the original virus that causes COVID-19. They also provide some protection against Omicron, but not as much as the updated (bivalent) boosters.
  • Two COVID-19 vaccine manufacturers, Pfizer and Moderna, have developed updated (bivalent) COVID-19 boosters.
  • Getting a COVID-19 vaccine after you recover from COVID-19 infection provides added protection against COVID-19.
  • People who are moderately or severely immunocompromised have different recommendations for COVID-19 vaccines, including boosters.
  • COVID-19 vaccine and booster recommendations may be updated as CDC continues to monitor the latest data.

There are four approved or authorized vaccines in the United States.

  • Pfizer-BioNTech and Moderna COVID-19 vaccines are mRNA vaccines.
  • Novavax COVID-19 vaccine is a protein subunit vaccine
  • Johnson & Johnson’s Janssen (J&J/Janssen) COVID-19 vaccine is a viral vector vaccine and can be given in some situations. The vaccines have been shown to be safe and effective.
