Recently, great advances have been made in the development of new monoclonal antibodies and vaccines thanks to the recognition of the structural conformation of virus proteins. The objective of this study was to review the advances related to the prevention of RSV infection in the first 6 months of life. Advances in structural biology have shown that the RSV fusion protein (F-Protein) in its prefusion state (Pre-F) is an excellent antigen for developing monoclonal antibodies and vaccines to prevent respiratory syncytial virus (RSV) infections. A new single-dose monoclonal antibody, Nirsevimab, has greater neutralizing power than currently available Palivizumab, and prolonged protection for 5 to 6 months. Nirsevimab has demonstrated an efficacy of 76.8% (95% CI, 49.4 to 89.4) in preventing lower respiratory infection 150 days after vaccination, decreasing the risk of ICU admission by 90.1% (95% CI: 16.4-98.8). Clesrovimab is another single-dose monoclonal antibody that has also shown promising results in phase 1b-2a trials. More recently, a bivalent vaccine against RSV A and B (Bivalent Prefusion F) has also been developed by replicating the F-protein stabilized in its Pre-F state as an antigen, using genetic engineering. This antigen, when administered to pregnant women between 24-36 weeks of gestation, induces high levels of antibodies in the mother with high transplacental transfer to the fetus. This vaccine has demonstrated an efficacy of 81.8% (95% CI: 40.6-96.3) at 90 days and 69.4% (95% CI: 44.3-84.1) at 180 days to prevent severe RSV disease (primary endpoint) without safety events detected so far.
