People ages 18 years and older who received both a primary dose and a booster dose of J&J/Janssen COVID-19 vaccine at least 4 months ago. ![]() People ages 12 years and older who are moderately or severely immunocompromised who received an initial COVID-19 booster dose (regardless of which vaccine was used) at least 4 months ago and.People ages 50 years and older who received an initial COVID-19 booster dose (regardless of which vaccine was used) at least 4 months ago.The CDC recently updated its booster vaccine recommendations to ensure certain vulnerable populations have the best protection against COVID-19 illness. Should I get a second booster dose if I'm eligible? However, with the Delta and Omicron variants, we have seen reduced protection against mild and moderate disease over time. No. The COVID-19 vaccines are working very well to prevent severe illness, hospitalization, and death, even against new variants. If I need a booster dose, does that mean that the vaccine is not working? Additionally, booster doses of the Moderna vaccine are half of the dose used in the primary series. Booster doses are given for many vaccines to "boost" the immune response (e.g. The additional dose is considered to be part of their primary series.Ī “booster dose” is a supplemental vaccine dose given to people when the immune response to a primary vaccine series was adequate but is likely to have decreased over time. This is because they may not have received adequate protection from their initial 2-dose vaccine series. What’s the difference between a booster shot and an additional dose?Īn “additional dose” refers to people who are moderately to severely immunocompromised receiving an additional dose of an mRNA COVID-19 vaccine (Pfizer-BioNTech or Moderna). However, use of an mRNA vaccine is preferred in most situations. Some individuals may choose to get a different vaccine for their booster based on local availability, or individual risks and benefits. You can "mix and match" booster dose in eligible individuals following completion of primary vaccination with a different COVID-19 vaccine. People who got the Janssen (J&J) vaccine should get a booster at least 2 months later.Ĭan I get a different vaccine booster dose than the vaccine I originally got? People who got the Pfizer-BioNTech or Moderna vaccines should get a booster at least 5 months after completing the primary series. Timing on when to get a booster depends on which vaccine you received as your primary series. Who can get a COVID-19 vaccine booster? (as of 1/6/22)ĬDC is recommending that all individuals aged 12 and older should get a booster. ![]() ![]() The CDC has detailed recommendations and clinical considerations to help individuals decide if they need a booster, which vaccine to choose, and whether a different vaccine is appropriate.Ībout the Boosters and Eligible Populations The timing for an mRNA booster has also changed to be given at least 5 months following the second dose of the Pfizer-BioNTech or Moderna vaccines. Individuals 12-17 can also receive a booster dose following completion of a primary series with Pfizer-BioNTech vaccine. With the new EUA amendments, all individuals 18 and older should receive a single booster dose of either vaccine, even if it different from their primary series. CDC Updates Recommendations for mRNA COVID-19 Vaccine Booster Doses These recommendations have been reviewed and approved by the AAFP. This is especially important as the Omicron BA.2 subvariant becomes the dominant strain in the U.S. On March 29, after an expedited FDA review of evidence, the CDC updated its recommendations to allow a second booster dose of mRNA COVID-19 vaccine in individuals age 50 years and older and in people with certain types of immunocompromising conditions.
