If the nasal spray blocks this COVID working in humans, it could change the course of the pandemic



Scientists at Columbia University have developed a nasal spray that prevents coronavirus from infecting the nose and lungs.

If it works in humans – the spray has not yet been tested in humans – it could become an effective, low-cost preventive measure while we wait for an effective vaccine, The New York Times report.

Dr Arturo Casadevall, head of the department of immunology at the Johns Hopkins Bloomberg School of Public Health, who has not worked on the spray, said: “It is very exciting to have something new that works against coronavirus. taste. THE CURRENT. “I can imagine this as part of an arsenal.”

The team tested the aerosol on cells and cultured mink, finding in their study ̵

In one small study, COVID-free weasels placed in cages with a COVID-infected weasel remained healthy, while the placebo-given weasels eventually captured the coronavirus.

“If it works well in humans, you can either sleep in bed with an infected person or stay with your infected children and stay safe,” said Dr. Ann Moscona, study co-author and doctor. Columbia, pediatrics and microbiology, told THE CURRENT.

The next step will be to test the nasal spray on volunteers, but Moscona says the team needs to raise more funding before it can.

If it succeeds, THE CURRENT Reportedly, spraying could become an attractive way to slow the spread of disease until vaccines become available. It appears to completely suppress viral replication in studies, significantly reducing the risk of exposure to people with COVID-19. And because it doesn’t require refrigeration, the team says production and distribution will be significantly cheaper than other more fragile treatments.
