Summary of the Article: cell-Based Flu Vaccine Effectiveness in Young Children
This article from Healio News reports on new research presented at IDWeek 2025,providing the first real-world evidence of the effectiveness of cell-based influenza vaccines in children as young as 6 months old. Previously, these vaccines were only officially indicated for this age group starting in October 2021.
Key Findings:
* The study, led by Alicia N. Stein, PhD, MBiostat, showed the cell-based flu vaccine was associated with a real-world vaccine effectiveness (rVE) of 66% against medically attended influenza.
* This level of effectiveness is estimated to have a ample positive impact on public health for both children and adults.
* The research supports a more comprehensive understanding of the vaccine’s impact, leading to better health outcomes and informed decision-making.
