How Well COVID-19 Vaccines Work

  • People who are up to date have lower risk of severe illness, hospitalization and deathfrom COVID-19 than people who are unvaccinated or who have not completed the doses recommended for them by CDC.
  • Additional updated COVID-19 vaccine doses can help restore protection that has decreased since previous vaccination.
  • CDC will continue to provide updates as we learn more.

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 from COVID-19 when you stay up to date with the recommended vaccinations.

COVID-19 vaccines recommended for use in the United States:

  • Pfizer-BioNTech
  • Moderna
  • Novavax

COVID-19 Vaccines: 2023–2024 Updated, Bivalent, and Original

2023–2024 updated COVID-19 vaccines

As of October 3, 2023, the 2023-2024 updated Novavax vaccine was recommended by CDC for use in the United States.

As of September 12, 2023,the2023–2024 updated Pfizer-BioNTech and Moderna COVID-19 vaccines were recommended by CDC for use in the United States.

The 2023–2024 updated COVID-19 vaccines more closely targets the XBB lineage of the Omicron variantand could restore protection against severe COVID-19 that may have decreased over time. We anticipate the updated vaccines will be better at fighting currently circulating variants.

There is no preferential recommendation for the use of any one COVID-19 vaccine over another when more than one licensed or authorized, recommended, and age-appropriate vaccine is available.

2022–2023 Bivalent vaccines

As of September 11, 2023,the bivalentPfizer-BioNTech and ModernaCOVID-19 vaccines are no longer available for use in the United States.

The 2022–2023 bivalent vaccines were designed to protect againstboththe original virus that causes COVID-19andthe Omicron variants BA.4 and BA.5. Two COVID-19 vaccine manufacturers, Pfizer-BioNTech and Moderna, had developed bivalent COVID-19 vaccines.

Original vaccines

As of April 18, 2023,theoriginalPfizer-BioNTech and ModernaCOVID-19 vaccines are no longer available for use in the United States.

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

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

Getting Vaccines If You Recently Had 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 vaccine by 3 months.

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:

  • personal risk of severe disease,
  • risk of disease in a loved one or close contact,
  • local COVID-19 hospital admission level,
  • and the most common COVID-19 variantcurrently causing illness.
