Anti-COVID nasal spray could protect against infection for up to 8 hours: researchers - Fox News

Scientists at the University of Helsinki have developed a novel nasal spray treatment that can reportedly provide protection against COVID-19 "for hours." .

A release from the university said the Finnish researchers had developed a molecule that has the ability to inactivate the coronavirus spike protein and offers effective short-term protection against the virus. .

It said that cell cultures in a petri dish and animal studies have shown that the TriSb92 molecule protects against infection for "at least eight hours even in cases of high exposure risk" and is effective immediately after its administration. .

"Our results highlight the potential of intranasal inhibitors in protecting susceptible individuals from SARS-CoV-2 infection, and describe a novel type of inhibitor that could be of use in addressing the challenge posed by the omicron variant," they said. .

"In animal models, nasally administered TriSb92 offered protection against infection in an exposure situation where all unprotected mice were infected," postdoctoral researcher Anna Makela, the first author of the study, said in a statement

"Targeting this inhibitory effect of the TriSb92 molecule to a site of the coronavirus spike protein common to all variants of the virus makes it possible to effectively inhibit the ability of all known variants, omicron included, to infect people," she explained, noting the molecule was able to prevent the spread of SARS, potentially indicating future variants of SARS-CoV-2 or new coronaviruses could be "susceptible to it."

The nasal spray treatment is not a vaccine for COVID-19 and University of Helsinki's professor Kalle Saksela – who works in the laboratory with Makela – is involved in the development of a Finnish nasally administered coronavirus vaccine, which is expected to progress to clinical trials in the spring
