Ann: Positive Intranasal Animal Data against SARS-CoV-2 in Study, page-12

It seems a bit hard to really tell how important this result is. The previous trial results by others using ferrets made the results quite clear and significant when if I recall they stated treated ferrets were put in with infected ones and none became infected, while placebo were infected. The scaling may be deceptive a little but that placebo dot is a bit close for comfort.
Seems rce certainly offers some improvement of infection but not sure how significant that is.
