Wow, that's cool! It is interesting that actual scientists have thought of the same idea. The idea may still be relevant given how long it is taking the entire world to be vaccinated. There is a serious risk of new even more dangerous variants emerging as long as the entire world is not vaccinated. Releasing an "attenuated variant" into communities that cannot be vaccinated quickly may still be necessary.
