Show 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.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
