Research on nasal sprays raises hope for COVID protection



(Reporter)
A coronavirus-attacking nasal spray has been discovered to protect a small group of ferrets, raising hope that this solution might do the same in humans. The aerosol is inexpensive to make and requires no refrigeration, report The New York Times, which note that if this goes away, “daily runny nose will act like a vaccine.” The spray was described in a study shared online Thursday. Research has been submitted to the journal Science but not approved. However, Dr. Peter J. Hotez of Baylor College of Medicine says that the spray looks “really promising”

;, according to Times. Dr. Arturo Casadevall of the Johns Hopkins Bloomberg School of Public Health says he could see it “as part of an arsenal” used to fight viruses – if proven effective in humans. Like humans, ferrets can catch viruses through the nose, according to Telegraph.

Microbiologist Anne Moscona, co-author of research funded by the National Institutes of Health and Columbia University Medical Center, said researchers are awaiting patent approval for the spray only. effective in 24 hours. In the meantime, she hopes Columbia will contact the federal government or pharmaceutical companies as more funding is needed to initiate human clinical trials. The study claims a daily dose given to six weasels “completely suppressed transmission from direct exposure to SARS-CoV-2 during 24 hours of staying with infected animals.” The spray was active on four variants of the virus and also provided some protection against SARS and MERS, the researchers said. “If it works well in humans, you can sleep in bed with the infected person … and still be safe,” Moscona told Times. (A similar product is being tested in humans in China.)
