Americans get raped by big pharma because other countries put in price controls to try and ensure their citizens can have access to much needed medication. Not so much here.
But with that said there is no way that someone without health insurance or the funds to spend $3,120 on a vaccine are going to be denied access to it. We already saw the federal mandate that testing had to be covered 100% by all health insurance plans self-funded or fully insured so regardless. CMS is reimbursing up to $100 to providers and through private insurance, the carriers are reimbursing around $60. But yes there are providers who do not accept insurance that are charging much more than $100 for a test and those providers should be named and shamed.
Specific to COVID-19 any pharma company that tries to put profits before people are going to find their share price plummeting fast.
I have no concerns that when (if) a vaccine is created everyone who wants it will at some point get it.
