Real-World Effectiveness of Maternal RSVpreF Vaccination and Durability of Infant Protection
By Xu H, Aparicio-Llorente C, Wats A and 14 others.
Abstract
In this test-negative study, the effectiveness of the maternal RSVpreF vaccine among infants <6 months was 73.9% against medically attended respiratory syncytial virus (RSV) infection and 86.3% against RSV-associated hospitalization. Maternal RSVpreF and nirsevimab had comparable initial effectiveness, but effectiveness of RSVpreF waned approximately 1.7 times more rapidly.
