A change to the official health advice in the ACT now recommends Canberrans received their second dose of the Astra Zeneca vaccine within 4-8 weeks of their first shot.

Originally, the optimal time between jabs for the AZ vaccine was 12 weeks to allow greater protection.

However, Chief Minister, Andrew Barr, said this latest change was based on advice from the Chief Health Officer in line with guidance from the Australian Technical Advisory Group on Immunisation.

“The best vaccine is the one that you can get today.”

“We want to see more Canberrans fully vaccinated faster to give them protection during this outbreak.”

Canberrans with existing appointments are now being encouraged to bring them forward.

While those aged 18 and over who are waiting for a Pfizer appointment and who are keen to get vaccinated sooner are being encouraged to have a chat with the GP to consider the Astra Zeneca jab.


Chief Health Officer, Dr Kerryn Coleman, said the vaccine is an important tool in the Territory’s fight against the delta strain of COVID-19.

“Bringing forward your second dose may have a small effect on long-term protection of AstraZeneca vaccine but will make sure you are protected earlier.”

“We know the vaccines are very effective at preventing illness and death.”

“The Delta variant is easier to catch and most importantly is right here in our community.”
