Although palivizumab and nirsevimab, neutralizing antibodies (nAbs) targeting the RSV F protein, have been used for prophylaxis, their limitations underscore the need for more effective alternatives. Herein, we present a potent and broad nAb, named 5B11, which exhibits nanogram level of unbiased neutralizing activities against both RSV-A and -B subgroups. Notably, 5B11 shows a ~20-fold increase in neutralizing efficacy compared to 1129 (the murine precursor of palivizumab) and approximately a 3-fold increase in neutralizing efficacy against B18537 in comparison to nirsevimab. Cryo-electron microscopy analysis reveals 5B11’s mechanism of action by targeting a highly conserved epitope within site V, offering a promising strategy with potentially lower risk of escape mutants. Antiviral testing in a female cotton rat model demonstrated that low-dose (1.5 mg/kg) administration of 5B11 achieved comparable prophylactic efficacy to that achieved by high-dose (15 mg/kg) of 1129. Furthermore, the humanized 5B11 showed a superior in vivo antiviral activity against B18537 infection compared to nirsevimab and palivizumab.

Combining virological assays with hydrogen/deuterium exchange mass spectrometry, and atomic force microscopy, we investigate the effect of capsid-HS binding and structural activation. We show how HS-induced structural activation requires a minimal HS-chain length and simultaneous engagement of several binding sites by a single HS molecule. This engagement introduces a pincer-like force that stabilizes the capsid in a conformation with extended capsomer linkers. It results in capsid enlargement and softening, thereby likely facilitating L1 proteolytic cleavage and subsequent L2-externalization, as needed for cell entry.
