How Pneumococcal Vaccine Efficacy Is Measured and Affirmed

This segment breaks down how pneumococcal vaccine efficacy and effectiveness are measured and why these distinctions matter when interpreting clinical trial data and real-world outcomes. It also explores the role of immunobridging in the approval of newer pneumococcal conjugate vaccines, key clinical end points used to evaluate vaccine performance, and what serotype differences mean for patient protection. Together, these insights help pharmacists translate evidence into informed, patient-centered vaccination decisions.
