ABSTRACT
We estimated interim influenza A vaccine effectiveness (VE) following a late sharp rise in cases during an influenza A(H3N2)-dominated 2021/22 season, after lifting COVID-19 restrictions. In children aged 2-6 years offered a live attenuated influenza vaccine, adjusted VE was 62.7% (95% CI 10.9-84.4) in hospitalised and 64.2% (95% CI 50.5-74.1) in non-hospitalised children. In non-hospitalised patients aged 7-44 years, VE was 24.8% (95% CI 12.8-35.2); VE was non-significant in remaining age groups and hospital/non-hospital settings.
