"A Daily Spritz Up The Nose"

As Instapundit would say: Faster, please.

Per the New York Times:  "A nasal spray that blocks the absorption of the coronavirus completely protected ferrets it was tested on, according to a small study released Thursday by an international team of scientists. The study, which was limited to animals and has not yet been peer-reviewed, was assessed by several health experts at the request of The New York Times.

If the spray, which the scientists described as nontoxic and stable, is proved to work in humans, it could provide a new way to fight the pandemic, with a daily spritz up the nose acting like a vaccine."
