Revolutionary Nasal Spray Disrupts All COVID-19 Variants.

Researchers at the University of Helsinki have developed TriSb92, a molecule that can prevent infection from all known SARS-CoV-2 variants when administered nasally. The molecule targets a common region in the virus’s spike protein and inhibits its functioning. Experiments on cell cultures and animal models have shown its efficacy against even the latest variants, and it remains functional at room temperature for at least 18 months. This breakthrough has the potential to be a key tool in combating future pandemics by preventing transmission and spread of the virus.
