Health department reviewing fifth COVID-19 vaccine. But what if you have missed a dose?
Australians will consider further vaccination against COVID-19 with new booster recommendations to be made ahead of winter.
The Australian Technical Advisory Group on Immunisation (ATAGI) is expected to make a decision on the fifth dose within weeks.
Currently, only those who are severely immunocompromised and over 16, are eligible to get the fifth COVID-19 jab.
As federal authorities prepare to recommend a fifth jab, what happens if you have skipped a dose?
Here's what we know so far.
What if I haven't had my fourth dose yet?
"We really need to think about how recent someone's last vaccine was, rather than how many doses they have had," Monash University associate professor James Trauer says.
"Evidence for the fourth dose was that people were protected for a few months, but that the protection waned back to the level we would see for three doses relatively quickly.
"So these repeated boosters seem to be providing a window of extra protection for a few months.
"This protection is likely to be quite important for the elderly and those with medical conditions, and so we do need to be looking at repeated vaccination as we head into waves of transmission."
What are the recommended intervals between booster doses?
Three months is the recommended time between completing the primary COVID-19 vaccine course and the first booster.
The recommended interval between the first booster dose and a second booster dose (for those who are recommended to receive a second booster dose) is also three months.
ATAGI advises there is no upper time limit for the administration of a booster dose, but notes vaccine effectiveness wanes over time.
What vaccine am I eligible for?
For adults under 60, Pfizer, Moderna, or Novavax are preferred by ATAGI over AstraZeneca for the first two doses, while there is no preferred brand for people over 60.
For pregnant women, Pfizer and Moderna are recommended and Novavax is also an option, but AstraZeneca is not preferred.
