March 31, 2023 – An antiviral therapy in early development has the potential to prevent COVID-19 infections when given as a nasal spray as little as 4 hours before exposure. It also appears to work as a treatment if used within 4 hours after infection inside the nose, new research reveals.
Unlike a COVID vaccine that boosts a person’s immune system as protection, the antiviral nasal spray works more directly by blocking the virus, acting as a"biological mask in the nasal cavity," according toThe product targets a stable site on the spike protein of the virus that is not known to mutate. This same site is shared among many variants of the COVID virus, so it could be effective against future variants as well, researchers note.
“TriSb92 could effectively tip the balance in favor of the [the person] and thereby help to reduce the risk of severe COVID-19 disease,” she said.“Many elderly people as well as individuals who are immunodeficient for various reasons do not respond to vaccines, and are in the need of other protective measures,” said Kalle Saksela, MD, PhD, senior author of the study and a virologist at the University of Helsinki.

I think the window is too narrow. Many people, likely most people, aren’t aware of their exposure within 4hrs. Perhaps it could be useful if going to a large indoor gathering as a preventive measure.
The tickler is how you know that you've been exposed or is it possible to use it before going out or being around other people?
This is what certain doctors said from the beginning but were shunned because of it
I’ve actually been using a saline nasal spray after each time I’m in public and every morning + evening. Also wear an N95 100% of the time in public. Haven’t had a cold, cough, or COVID in the past 3+ years. It’s really the only strategy that works.
