Abstract

We identified 80 pediatric influenza-associated deaths in Canadian pediatric tertiary hospitals from 2004 to 2022. Children aged <5 years and with high-risk conditions represented 55% and 77.5% of cases, respectively. Only 24.5% of age-eligible hospitalized cases with known vaccination status had been immunized against influenza that season. Vaccination efforts should be enhanced to reduce influenza mortality.
