Pediatric Inpatient Influenza Vaccination Before, During, and After the COVID-19 Pandemic.

In this multi-site retrospective study, we evaluated influenza vaccination of hospitalized children during the 2018-2019 through 2023-2024 seasons. While screening varied across sites, influenza vaccine administration was lower in the pandemic and post-pandemic period for all sites. These results highlight the need for strategies to promote vaccination in hospitalized children.
