On February 10, 2022 the Australian Technical Advisory Group on Immunisation (ATAGI) updated the defining of COVID-19 vaccination status from “fully vaccinated” which served for the 2-dose practice, but with boosters now in place they introduce the terminology of being “up-to-date”.  ” It forms the basis of the due and overdue rules for the Australian Immunisation Register (AIR).” [1, 2]

With any of the TGA provisionally approved CV19 vaccines (except J&J), 14 days post the second jab, is a minimum valid time frame for the primary doses to be considered ‘up-to-date’.”  Booster eligibility is from 3 months after the last primary dose, which includes that 14 day wait time – so actually 2 1/2 months.  “People who have not received a booster within 6 months of completing their primary series will be considered overdue”.
