Really question the findings by PFE & BNTX. Their study is based on pseudovirus. The Sigal Lab & Ciesek team used live virus, and both had shown much sharper declines than in the makers' study.

The only bright spot is 2xModerna + Pfizer booster that showed respectable titer vs. Omicron in Ciesek's study. No results on Moderna booster yet.

The mkt doesn't believe what Bourla, Sahin said either, judging by the BNTX performance.$Moderna, Inc.(MRNA)$ $Pfizer(PFE)$ $BioNTech SE(BNTX)$
