This drug might block the coronavirus without any pills or injections

A team of researchers from Ohio State University has developed tiny protein fragments that can block the novel coronavirus from infecting cells, and it could be turned into a potential COVID-19 treatment that can be administered by anyone. Much like neutralizing antibodies resulting from a coronavirus infection or vaccination, the peptides bind to the spike protein, preventing the virus from hooking up to ACE2 receptors and infecting cells. The peptides could be used to develop a nasal spray tha...
