Abstract
AbstractWe evaluated 2023 Southern Hemisphere influenza vaccine effectiveness against medically attended illness using surveillance data from nine Thai hospitals and a test-negative design. During June 2022–May 2023, influenza vaccine provided protection against seeking care for influenza illness (adjusted vaccine effectiveness 43%; 95% confidence interval 15–61).
