I remember reading about the research in making a virus that would be super contagious, but have mild symptoms that could be used to provide a population with immunity. At the time I was kind of pissed that they would try and make something that would spread through a community acting like a vaccine. But you know this sounds just like what is happening with this moronic variant. It give immunity with a case of the sniffles.
Perhaps that is why they are freaking out and trying to control it, because it will negate the kill shots and vax passports both of which are not for health but for control.
