Factor Eight isn't a drug as such. Sodium Valproate was introduced 1962. Thalidomide 1957. That's about 65 years ago. You have to go back 65 years for those two drug scandals. How many drugs have been introduced in those 65 years which have helped massively without going so wrong?
"Pfizer had been fined over three billion dollars for misrepresenting its products" is a bit inaccurate. They were fined a record $2.3bn for various illegal marketing acts, including direct payments to prescribers and encouraging "off-label" prescribing. Not misrepresentation. (Source
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2875889/ ) The total goes over $3bn and includes misrepresentation only when you add in various cases involving companies that Pfizer bought (Upjohn did a bit of mislabelling, for one), including some from before Pfizer bought them.
You really should check and give sources for this sort of wild claim, but also ask who's feeding you slightly-distorted claims and why.
And if someone didn't like the BioNTech vaccine because Pfizer got involved, there were others pretty soon after.
I'm pretty sceptical of pharma companies because of my experiences (I may never remember parts of my life) but I still felt it was worth trying to get vaccinated, as far as offered.
