And humans do not have a way to induce long lasting plasma cells to respond to with infection or present vaccines against SARS CoV2 and they ended mitigations after the vaccines - which provide protection for ~ 4 months:

Without Vaccines and/or Infections inducing Long Lasting Plasma cells - if we are not vaccinated - and relying on short lasting plasma cells with no mitigations - we are on the way to extinction - via disability from Long Covid already over 25% of Population.

In all, our studies suggest that rapid waning of SARS-CoV-2-specific serum antibodies could be accounted for by the absence of BM LLPCs after these mRNA vaccines. (same with infection)

With no Long Lasting Plasma cells against SARS CoV2 either by infection or vaccination - anybody against other mitigations - are either disinformation peddlers or minimizers- no other way!
Mitigations + boosters in that order- booster complement mitigations.

We have evidence since 2022 and now published: that there is no induction of Long Lasting Plasma Cells (pDCs, T cells and NK Cells are ineffective against this virus)
