But I don't have time to summarize:
There's a lot in here, so this is just a teaser:
Both Moderna’s and Pfizer’s mRNA vaccines use specialized nanoparticle lipids or lipoproteins as carriers for their main ingredient – unstable mRNA protein that causes cells to produce the notorious coronavirus spike protein and elicit an immune response. These are the molecules that required the extremely low temperatures to preserve stability of the lipid encasing the fragile mRNA.
Accumulation in reproductive organs
German researchers reported in their paper published nine years ago, “Accumulation of nanocarriers in the ovary: A neglected toxicity risk?,” that there is a “potential toxicity risk of all nanoscaled drug delivery systems” and an accumulation of different microscopic carrier molecules in rodent ovaries. Their research involved injection of lipid “nanocarriers,” including some with an ingredient common to both Pfizer’s and Moderna’s mRNA COVID vaccines: polyethylene glycol.
