Booster vaccinations can be given 3 months after your second dose of a COVID-19 vaccine.
Studies show that the immunity created by COVID-19 vaccines begins to wane over time. A booster dose helps to strengthen your immune system and improve your long-term protection against serious illness from the COVID-19 virus.
The Pfizer and Moderna mRNA vaccines are recommended as boosters in Australia. Although not preferred, the AstraZeneca vaccine can be given as a booster for those who are unable to have an mRNA vaccine for medical reasons.
COVID-19 booster vaccines are not mandatory. They are highly recommended to continue to protect you, your loved ones and your community against COVID-19.
From 11 December 2021, ATAGI says the weight of evidence suggests that a booster vaccine increases antibody levels substantially and this will likely offer protection against both delta and the new omicron variant.
