Four COVID-19 vaccines are approved or authorized in the U.S.:

  • Pfizer-BioNTech
  • Moderna
  • Novavax
  • Johnson & Johnson’s Janssen (J&J/Janssen)
    • Please note: The CDC recommends that the J&J/Janssen COVID-19 vaccine only be considered in certain situations due to safety concerns.


COVID-19 vaccine boosters can further enhance or restore protection that may have decreased over time after your primary series vaccination. People are best protected from severe COVID-19 illness when they stay up to date with their COVID-19 vaccines, which includes getting all recommended boosters when eligible. Eligibility varies based on age, medical history and vaccine brand. For more information, visit the CDC website.


Like all vaccines, COVID-19 vaccines must go through a rigorous and multi-step testing and approval process before they can be used. Developers of a vaccine must provide a large amount of data on its safety and effectiveness to meet the rigorous standards set by the FDA. There are also ongoing safety monitoring systems in place by the CDC and FDA to allow for continued monitoring of the vaccine.

Side effects

Side effects that have been reported for the COVID-19 vaccines are like those of other vaccines, including joint pain, muscle pain, fatigue, fever greater than 100.4, chills and headache. But remember, side effects appear to be a good indication of a healthy immune response to fight the virus.
