ATAGI have provided recommendations for the use of the Pfizer bivalent COVID vaccine following its recent provisional approval by the TGA. This means that there are now 2 bivalent COVID vaccines available for use within Australia- Moderna and Pfizer. 

The Pfizer bivalent vaccine contains equal parts of mRNA from the spike protein of the original SARS-CoV-2 virus and the Omicron BA.1 variant.  

ATAGI recommends that the Pfizer bivalent vaccine may be given to anyone aged 18 years or over who is eligible for a booster dose. It is not recommended for use in a primary course of COVID vaccination.  

There is no preference for either brand of bivalent or original mRNA COVID vaccines as a booster dose.
