Six weeks out - I'm guessing by then about 55-60% seroprevalence - 40-45% had it or were vaccinated 15%. That has to be way over the seroprevalence in the UK when it took off. Also, our most at risk will likely be vaccinated or at least had the opportunity to be vaccinated by then. I just don't see where we are going to "see something like we have not seen yet in this country". And, oh yeah, the UK was bad, but not worse than what we have seen, and again, at lower seroprevalence and not having the high-risk group vaccinated.
Well, from what I gathered from part of my father's reasoning, the new variants might be more infectious against even those who have had it before, but maybe not have gotten a full immunity (such as the asymptomatic carriers we've heard so much about). Further, he's worried that evolutionary pressure will begin to steer the variants away from vaccine coverage. He also thinks the govt is just lying about the more contagious, not more deadly part, to avoid a panic. Again none of this based in science. Just irrational panics of what ifs.
