Yeah, I checked...

the variants they tested in the preprint were all pre-omicron, and their analysis relied on TMPRSS2-expressing cells, and this route is non-functional in Omicron.

I would love to answer the question of whether Omicron can do this. I suspect it can, but at a much lower level.. less inflammation in the body -> less BBB leakage -> less brain infiltration.. and if we treat it? Likely no problem at all (my opinion).

-> The jabs, however, STILL have the original OG spike encoded in them,
-> The mRNA-jabs WILL cross the BBB.
-> The spike's genetic code MAY be reverse-transcribed / integrated into DNA via RT or Plasmid integration - the resulting persistent overwhelming dose of spike would be very bad, even for a young immune system...
