Randomized controlled trials have shown data supporting the safety and efficacy of cell-based influenza vaccines in adults and children.1-4 However, effectiveness studies have historically relied on outcomes based on clinical diagnosis of influenza-like illness rather than test-confirmed influenza.5 Test-confirmed influenza outcomes provide a more specific evaluation of influenza vaccine effectiveness and can help reveal the clinical differences between cell-based versus egg-based vaccines.6 A retrospective test-negative real-world study including more than 106,000 patients compared the cell-based vaccine with egg-based vaccines.7 Dr. Jennifer Caudle sits down with Dr. Wendy Wright to review the key findings from this analysis and their implications. Dr. Wright is a board-certified adult and family nurse practitioner based out of Amherst, New Hampshire as well as the owner of Wright and Associates Family Healthcare.
