About COVID-19 Vaccines

COVID-19 vaccines available in the United States are effective at protecting people from getting seriously ill, being hospitalized, and dying. As with other vaccine-preventable diseases, you are best protected best from COVID-19 when you stay up to date with the recommended vaccinations.

COVID-19 vaccines authorized in the United States:

  • Pfizer-BioNTech
  • Moderna
  • Novavax
  • Johnson & Johnson’s Janssen (J&J/Janssen)

Updated (Bivalent) and Original (Monovalent) COVID-19 Vaccines

Updated vaccines, sometimes called “bivalent” vaccines

The updated vaccines are called “updated” because they protect against both the original virus that causes COVID-19 and the Omicron variant BA.4 and BA.5. Two COVID-19 vaccine manufacturers, Pfizer-BioNTech and Moderna, have developed updated COVID-19 vaccines.

Original vaccines, sometimes called “monovalent” vaccines

Previous COVID-19 vaccines are called “original” because they were designed to protect against the original virus that causes COVID-19.

As of April 18, 2023, the original Pfizer-BioNTech and Moderna COVID-19 vaccines are no longer authorized for use by the FDA in the United States. Updated Pfizer-BioNTech and Moderna COVID-19 vaccines are being used for all age groups.

As of May 6, 2023, J&J/Janssen COVID-19 vaccine has expired and is no longer available for use in the United States.

Getting Vaccines If You Had or Currently Have COVID-19

If you recently had COVID-19, you still need to stay up to date with your vaccines, but you may consider delaying your next vaccine dose by 3 months from:

  • when your symptoms started.
  • or, if you had no symptoms, when you first received a positive test.

Reinfection is less likely in the weeks to months after infection. However, certain factors could be reasons to get a vaccine sooner rather than later, such as:
