In Early Testing, Nasal Spray Shows Signs It Can Fight COVID-19

Over two years into the pandemic, researchers are still searching for new and better ways to help people avoid COVID-19. While COVID-19 vaccines and boosters have been helpful at protecting people from severe hospitalization and death, they have been less effective at preventing symptomatic cases of the disease. Now researchers are looking at novel ways to keep COVID-19 from infecting human cells. ResearchersTrusted Source at Cornell University have been testing a nasal spray that blocks COVID-19 infection. Their study discovered a small molecule that, if sprayed into the nose, may help prevent COVID-19 from infecting cells. The study is still in its early stages and is currently only being tested in mice. But experts are hopeful that this type of study may help lead to better protection against the virus.
