2022 flu vaccine composition announced for Australia

The WHO’s advisory body on flu vaccination has determined the vaccine composition for our next influenza season, making changes to two of the strains – the H3N2 and influenza B/Victoria lineage components. It will also mean that two strains will be different when comparing that Southern Hemisphere formulation to the one for use in the Northern Hemisphere’s flu season this year. The WHO has provided a Q&A document covering ‘Recommended composition of influenza virus vaccines for use in the southern hemisphere 2022 influenza season and development of candidate vaccine viruses for pandemic preparedness’. More testing of influenza specimens have been performed this year compared to last, but overall there were few viruses to analyse. More flu news in the Sep 27 WHO global flu update. Read more
