Won't this take too long to run human trials on for safety/efficacy for it to really matter? My understanding is that a vaccine will likely come out within 6 months or so. They mention that it's an older compound, but sounds like they made some novel changes to it. Since this situation is so much a race against time, we are probably better off focusing on older, better-understood compounds that don't need to be tested for as long.

A vaccine would be great, but it’s far from certain we’ll have one in 6 months. It makes sense to keep pursuing multiple lines of research.

A great vaccine still won't work for everyone. The biggest group being those whose immune systems are not functioning well, which depending on the vaccine could include a large chunk of the elderly most at risk.

It's very unlikely a safe vaccine will come out six months from now. It's even more insane to think most people around the world will allow themselves to be injected with something developed in less than a year.

Effective treatment will be much more likely to hit the market than a vaccine.

They offer it as a stopgap, which, I agree with you, seems improbable given the latest reports on vaccines:

Used once a day, AeroNabs could provide powerful, reliable protection against SARS-CoV-2 until a vaccine becomes available.

But maybe that's a signal that these researchers believe much of the vaccine news has been overly optimistic hype. I guess the race is on.

One question I don't think the article addressed: if successful, would this have applications beyond Covid-19? Like against the common cold?
