TLDR
A viral antigen is sought that provides greater protection than currently available vaccines and focused on antigenic site Ø, a metastable site specific to the prefusion state of the RSV fusion (F) glycoprotein, as this site is targeted by extremely potent RSV-neutralizing antibodies.
Abstract
Respiratory syncytial virus (RSV) is the leading cause of hospitalization for children under 5 years of age. We sought to engineer a viral antigen that provides greater protection than currently available vaccines and focused on antigenic site O, a metastable site specific to the prefusion state of the RSV fusion (F) glycoprotein, as this site is targeted by extremely potent RSV-neutralizing antibodies. Structure-based design yielded stabilized versions of RSV F that maintained antigenic site O when exposed to extremes of pH, osmolality, and temperature. Six RSV F crystal structures provided atomic-level data on how introduced cysteine residues and filled hydrophobic cavities improved stability. Immunization with site O–stabilized variants of RSV F in mice and macaques elicited levels of RSV-specific neutralizing activity many times the protective threshold.

Combination nanovaccines against respiratory pathogens

Sean Kelly
TL;DR: These pathogens are highly lethal if inhaled, with mortality rates approaching 100% if untreated after only a few days, and both of these pathogens have been used as biological weapons to cause harm to civilians and military personnel, with the most recent being the 9/11 attacks in the United States in 2001.
