Vaccines are an absolutely revolutionary technology.
That said, mixing profit with essential medical technology is a recipe for failure.
The first way to make something more profitable is to cut costs.
What corners do these corps cut to up their margins? And how does that decrease health outcomes for some percent of the population?
The bottom-line is that no for-profit corp can be trusted with your health.
Vaccines must be developed and distributed by the government for the benefit of all human beings. Sure, we need to minimize cost but not to enrich the select few wealthy enough to be investors in the first place. If there is a surplus (profit), that money gets invested right back into R&D. No pharma-bros needed or wanted.
I am pro-vaccine and anti-for-profit-corps.
Yes, my kids are vaxed for measles and a few others, but, no, I did not go in for the entire schedule, which is frankly insane. Just compare our vax schedule in America to what they do in Europe. It's maybe 2x. And, yes, we will all get a Covid vax as soon as it is available.
But, remember, selling three of something (ETA: instead of two) that has a little margin gives you a 50% increase in profit. B-School types don't care that that third dose might be too much; besides, they can find/fund researchers to goal-seek safety for that extra 50%.
And, yes, vax is big business, just not as big as other meds.
And, yes, anti-vaxxers piss me off, too, the fucking anti-science morons. But people who trust for-profit corps with their health are stupid marks.
