The Australian Technical Advisory Group on Immunisation (ATAGI) provided an update on 29 April 2022 regarding dose intervals for Pfizer and Moderna COVID-19 vaccines and on COVID-19 vaccination post infection.
ATAGI advice on mRNA COVID-19 vaccine dose intervals
ATAGI now recommends the dose interval between primary doses for Pfizer and Moderna mRNA COVID-19 vaccines should be extended to 8 weeks.
The dose interval can be reduced (to a minimum of 3 weeks for Pfizer or 4 weeks for Moderna) for people at higher risk of severe COVID-19 (including older adults and people with underlying medical conditions), in an outbreak setting, or prior to international travel.
ATAGI advice on COVID-19 vaccination post infection
It is now recommended that all people should wait for 3 months after a confirmed SARS-CoV-2 (the virus that causes COVID-19) infection before they receive their next COVID-19 vaccine dose (including primary and booster doses). The next scheduled dose should then be given as soon as possible after this period.
This change in recommendation applies to all people who are recommended to receive COVID-19 vaccination, regardless of how many COVID-19 vaccine doses they have received. It does not apply to other vaccines (for example, influenza vaccinations) which can continue to be administered as usual.
