The goal of the Australian COVID-19 vaccination program remains the prevention of severe illness from COVID-19. ATAGI has evaluated this risk in the context of high population levels of hybrid immunity (i.e., combined immunity from past infection and past vaccination), the evidence regarding COVID-19 vaccine effectiveness, including for new bivalent vaccines, and the changing epidemiology of COVID-19 related to newly emerged subvariants of Omicron.

These recommendations replace previous ATAGI COVID-19 vaccine booster advice.
