Most Up to Date Information regarding COVID-19 BIVALENT Boosters

The updated boosters are called “updated” because they protect against both the original virus that causes COVID-19 and the Omicron variant BA.4 and BA.5. Two COVID-19 vaccine manufacturers, Pfizer and Moderna, have developed updated COVID-19 boosters.

Updated COVID-19 BIVALENT boosters became available on:

  • September 2, 2022, for people aged 12 years and older
  • October 12, 2022, for people aged 5–11 years
  • December 9, 2022, for children aged 6 months–4 years who completed the Moderna COVID-19 vaccine primary series


If you have received your updated booster dose, you are currently up to date. There is NOT a recommendation to get another updated booster dose at this time. You can look on your vaccination card and see if your last vaccination says Bivalent, if so you are up to date. If you are not sure if you are up to date, you can contact our office at (641) 464-0691 and we would be glad to look that information up for you!
