Cell-Based Quadrivalent Influenza Vaccines Outperform Egg-Based Counterparts in Preventing Test-Confirmed Influenza

Researchers compared the effectiveness of cell- and egg-based quadrivalent influenza vaccines (QIVc and QIVe, respectively) in preventing test-confirmed influenza over three US influenza seasons (2017-2020). The study, conducted by the Center for Outcomes Research, found that QIVc demonstrated superior effectiveness in preventing test-confirmed influenza in children and adults, with relative
