Benefits of Vaccination Outweigh the Risks Serious side effects that could cause a long-term health problem are extremely unusual following any vaccination, including COVID-19 vaccination.
The FDA has authorized the use of mix-and-match booster doses for currently available COVID-19 vaccines based on the results of a NIAID-supported study.
In most situations, mRNA COVID-19 vaccines (Pfizer-BioNTech or Moderna) are preferred over the J&J/Janssen COVID-19 vaccine for primary and booster vaccination due to the risk of serious adverse events.
Contraindications to COVID-19 vaccination include: Severe allergic reaction (e.g., anaphylaxis) after a previous dose or to a component of the COVID-19 vaccine. Known diagnosed allergy to a component of the COVID-19 vaccine (see Appendix C for a list of vaccine components).
If your immune system is compromised because of an underlying medical condition or medication you take, you should still get the COVID vaccine. The approved COVID vaccines do not contain a live virus and cannot infect anyone — immunocompromised or otherwise — with the coronavirus.
If you had COVID-19 before being vaccinated, the first injection may cause more noticeable side effects than for people who have not had the coronavirus. If you have never had COVID-19, you may notice more side effects after the second dose than after the first dose.
