Their track record of putting profit above people suggests not, so the framing of "Astrazenica pulls vaccine because of side effect" is really "Astrazenica pulls vaccine because they aren't making any money off it".

On that side of the ledger, regarding profit, Pfizer is likely to have been a strong competitor, w/help from Ursula von der Leyen (there are stories on her connection Pfizer on the web). Competition/budget and all that.

Probably parsing the negative effects in 'traditional' vacc (as in AstraZeneca) and the mrna 'treatment' could clarify that issue. An expert advice is needed + someone that can follow the money.
