There currently are four vaccines authorized for use by the Food and Drug Administration for adults for the primary series. Two are messenger RNA (mRNA) vaccines that are produced by Moderna and Pfizer-BioNTech. Both vaccines are administered in two doses. You should get your second shot as close to the recommended three-week or four-week interval as possible. Please note: the CDC now mentions persons 6 months to 64 years, and especially males ages 12-39, may consider getting the second primary dose 8 weeks after the first dose rather than 21 or 28 days. This may increase immune protection and minimize the rare risk of myocarditis. A third vaccine is a one-dose vaccine produced by Johnson & Johnson and a fourth vaccine is by Novavax using a standard methodology and requires two doses. At this time both the mRNA and Novavax vaccines are preferred due to greater efficacy.
With the variants continuing to spread and new variants possible at any time, it remains critical that:
People who have had more than one original (monovalent) booster are also recommended to get an updated (bivalent) booster.
