Coronavirus booster vaccinations will be available from GPs and pharmacies from Monday for those who had their second jab six months ago.
Deputy Chief Medical Officer Sonya Bennett said two doses are highly effective in preventing people from getting sick with COVID-19, but some studies have shown that immunity does tend to wane over time.
“For those people 18 and up who had a vaccine at least six months ago we encourage you to make an appointment and get your booster dose,” Dr Bennett told reporters on Sunday.
“There is plenty of vaccine for all of us to get our booster.”
Australia passed a major milestone over the weekend of having 80 per cent of the national population aged 16 and over fully vaccinated.
But Dr Bennett is urging everyone to get on board and be vaccinated.
“COVID will be in the community in each and every area of Australia over time as we open up,” she warned.
“Everyone will be at risk of being exposed to COVID. The best way to protect yourself against diseases is to get vaccinated.”
