Yes, please. We've been absolutely rocked by the recent plague circulating around schools
How can a nasal spray protect against bullets?
Maybe the spray has PCP in it so you just don't care about being shot.
You are assuming they are American.
Americans aren't too picky about who they shoot
Huh, I got arrested for breaking into an abandoned building...
I get the joke but for the sake of strict accuracy I'm so white I'm borderline translucent. I just meant that every mall around me is dead and abandoned.
Intentionally spread a new variant of a virus to create demand for a new vaccine because nobody cares about COVID anymore? I’d believe it.
Evolution will happen whether we want it or not and new strains will appear from time to time, just like we've seen with every virus ever known.
But if you still think that's what happened, we'd love to see your evidence of this new strain being man-made.
Exactly. Our immune system is excellent but its immune cell exploration space is on the order of 10^11 potential receptors.
So since RNA viruses in particular can mutate so rapidly, we just use our brains to reduce that by 10+ orders of magnitude and target the antigens we want directly. The end result is the same, biotech is just smarter.
