The first combination COVID booster has now been introduced to Australia's vaccine program, with Moderna's Omicron shot officially entering the rollout from today, according to the Department of Health and Aged Care.
The Australian Technical Advisory Group on Immunisation (ATAGI) last month recommended the shot, comprising of vaccines against the original SARS-CoV-2 virus and the BA.1 Omicron subvariant, be administered as a booster to adults.
Combination boosters have also been rolled out elsewhere, such as the UK, Switzerland, Canada, EU and US, with the US rolling out a booster tailored to BA.4 and BA.5 rather than BA.1.
