Today, the Therapeutic Goods Administration (TGA) has approved the Pfizer vaccine, Comirnaty, for use as a booster shot.

Adults in Australia may receive a booster (or third dose) at least six months after their second Covid-19 vaccine, regardless of which vaccine they received for their initial two doses.

So if you had two doses of AstraZeneca or Moderna, you will still be able to get the Pfizer booster.

TGA approved the booster dose following careful evaluation of the available data supporting safety and efficacy, but says in a statement, that “data on the use of Comirnaty as a booster with other Covid-19 vaccines is more limited”.

The provisional approval is now in the hands of the Australian Technical Advisory Group on Immunisation (ATAGI), who will advise the government on who gets to receive the booster first and when.

The TGA product information statement also says a third dose may be given to severely immunocompromised people aged 12 years and over at least 28 days after the second dose.

Federal Health Minister Greg Hunt confirmed the booster rollout will begin from Monday November 8, pending the ATAGI’s advice. Australians in aged care and those with disability will be considered a priority.

“It’s a universal booster,” said Mr Hunt. “It’s available for people who’ve had Pfizer, AstraZeneca or Moderna.”

ATAGI has already recommended that people who are severely immunocompromised should receive a booster dose two to six months after their second dose.
