Hadn't heard of this until I saw it in the Science section of the Sunday paper, and it is kind of breathtaking. There doesn't even seem to be a shorthand term for what this is. It's a completely different route to inoculation that is not a method of stimulating antibody production and is not even a synthetic antibody.
For now they are just calling it "machine-made molecules" or "mini-binders." They're gonna have to come up with a better term for it. It's sort of a vaccine, but sort of not. We may have to rethink exactly what the definition of "vaccine" is to even discuss it. But it is way cool. And it seems to work on hamsters.
If I understand this correctly, it's a decoy molecule that lures in marauding coronavirus with a very specific molecular bait, then grabs onto it and renders it harmless. If it works out, this substance could be cheaply manufactured, easily stored, and possibly self-administered as a nasal spray. Better yet, if the concept works on this virus, it would probably work on others. Maybe we are finally on the track of a cure to the common cold!
Hmm. "ACE-2 decoy" is kind of a snappy name. I vote for that. Mini-binders sounds like an office supply product, and machine-made molecules just sounds scary. Branding is important, y'all.
