3rd dose ... etc etc ... all i understand is more profits.

$Pfizer (PFE.US)$
A third dose increased antibodies 25-fold compared with two doses in the Omicron variant, the companies said.

what i understand is , since the virus got an upgrade. its time to consume more existing vaccine or , we can come up with an upgraded version of the vaccine (which most likely cost more)

either way , more projected profits/sales
