I will not research those numbers, because it's 2:30 AM and I should be in bed. 

But all I can say is that, considering that currently, vaccines represent 1% of "Big Pharma's" income - and are usually sold at cost, or even at a loss - a 3x increase, albeit significant in absolute terms, is pathetic in relative terms. It goes from being 1% do 2.9% of their income.

That is, IMO, not impactful enough to justify a cover-up spanning a couple decades. A cover-up that would decidedly cost them much more than they'd earn. I mean, think about it! In the US, there are ~850k doctors. How much do you think they'd have to pay for their collective silences? Keep in mind that the lowest annual income for physicians in the US is at 130k per year.
