Johnson & Johnson Not yet authorized for booster or third doses
Moderna Authorized only for third doses for people with compromised immune systems

The CDC does NOT recommend that people with a compromised immune system who have gotten a dose of the Johnson & Johnson vaccine start a new vaccination series with Pfizer or Moderna.

Are there risks of receiving an additional vaccine dose?

Limited information exists about the risks of receiving an additional dose of vaccine. Ongoing research is looking at the safety and benefit of additional doses of COVID-19 vaccines.

So far, reactions reported after a third dose of an mRNA vaccine were similar to those for first and second doses. The most common side effects reported have been fatigue and pain at the injection site. Overall, most side effects have been mild to moderate.
