Emory Vaccine Center researchers say they have identified the Achilles heel of SARS-CoV-2, the virus that causes COVID-19. Part of the viral fusion machinery seems to stay the same among several viral variants, and this vulnerable machinery is what the antiviral peptide Yongshi targets. A peptide is a small protein or fragment of a protein.  Derived from a natural antiviral peptide produced by wild boar, Yongshi (meaning "warrior" in Mandarin) can prevent SARS-CoV-2 from infecting host cells. The scientists are now studying how to adapt the peptide for clinical use.
