COVID-19 booster shots are set to be available to all Australians at the five-month mark.
A booster dose was initially recommended to be given six months after a second dose of the COVID-19 vaccine to ensure that protection from the virus is even stronger and long lasting.
However, with the Omicron variant, the rollout has been brought forward one month to help stop the spread.
Australians aged 18 and over will now have the choice to also receive a Moderna COVID-19 booster shot after the Australian Technical Advisory Group on Immunisation (ATAGI) approved it.
Irrespective of which vaccine you've had for the initial doses, people will be able to get either the Moderna or Pfizer booster shot.
Federal Health Minister Greg Hunt said Australia is one of the first countries to roll out a nation-wide booster program.
"Australia is well prepared to provide booster doses as approvals are provided by the medical experts," Mr Hunt said in a statement.
Over 8,500 GP's, pharmacies and clinics will be providing either or both Moderna and Pfizer boosters.
