Dosage Intervals for AstraZeneca Clarified

In a media release by the Australian Dental Association (ADA), The Australian Technical Advisory Group on Immunisation (ATAGI) has clarified the dosage intervals for AstraZeneca, recommending that in an outbreak setting, such as the current Delta strain we are currently facing, that an interval of 4 to 8 weeks is preferred. 

ATAGI is advising that anyone who has previously received an AstraZeneca vaccine more than four weeks ago contact their vaccine provider to expedite the administration of their second dose.

In the light of current constrained supplies of the Pfizer vaccine, ATAGI recommends that those over 60 who do not have immediate access to the Pfizer vaccine should consider the benefits and risks of earlier protection through the AstraZeneca vaccine.
