A good thing, but isn't this lower than the protection of vaccination?

Could be useful prophylaxis, could supplement. Could help for people who arent vaccinated. could be a cheap path for poor economies, but all of this begs the question: why can't we make vaccination available and routine?

Also, given the FUD about adverse reactions (and the misunderstanding about scale) -these sprays cause nasal bleeding, loss of sense of smell, and people reported tiredness. These aren't nothing right? So.. if you refused an mRNA vaccine because one in 50,000 people had an adverse reaction, you're willing to think your burger and fries tastes different at .. what rate?

Nasal vaccine delivery is also a thing. We could use this method to deploy both a preventive, and a vaccine.

There’s not enough information to know. It was only tested against the fully vaccinated people and, while it showed a boost to protection, that could simply be a result of irritation to the nasal passages putting the innate immune system on alert and thus leveraging the existing antibodies. A similar phenomenon can be seen with unrelated vaccinations giving a temporary boost to protection.

Thanks. So.. for people who get dragged into anti-vaxx discussions on this, as an alternative: it was tested on people who had been vaccinated. It's not fuel for a position oppositional to vaccination, almost by definition.

Or, and hear me out. The vaccine reduces infection by 90%.

Discussion of anything other than vaccines to prevent COVID is discouraged. Trust the experts.

No one's stopping you -- or anyone else -- from talking about this. That's why there's public research available.
