As you may be aware, the Australian Technical Advisory Group on Immunisation (ATAGI) has released a statement clarifying the dosage intervals for AstraZeneca in the context of a COVID-19 outbreak. The advice clarifies that in an outbreak setting, an interval of 4-8 weeks is preferred. In line with this, you may also have seen that Dr Kerry Chant, Chief Health Officer of NSW, has promoted a 6 week interval for individuals in Greater Sydney.

You can view ATAGI’s statement on the Department of Health Website.

All health professionals may receive questions from patients regarding these changes, so please refer to this information to help to explain the updated advice. Your assistance in this matter is greatly appreciated.
