27 October 2021 - The TGA has provisionally approved a booster dose of the Pfizer COVID-19 vaccine, Comirnaty, for individuals 18 years and older.
The provisional approval means that individuals aged 18 years and older may receive a booster (third dose), at least six months after the completion of a COVID-19 vaccine primary series. This primary series can be of any of the COVID-19 vaccines registered for use in Australia, although data on the use of Comirnaty as a booster with other COVID-19 vaccines is more limited.
