This is yet another example of the US healthcare funding model. While there are valid reasons for the cost to be relatively high, immunoglobulin treatments are expensive to prepare, it does not need to be that high. In single-payer systems (e.g. UK) the full cost of the same shot (generally not paid by the patient) is something like $800. It's not about subsidies, I'm talking about what the healthcare system pays to the multinational drug vendors for making the vial and also the relatively smaller cost of medical staff going the injection - that's what the treatment really costs, and the remaining $3200 is essentially the administrative/insurance/extra-profit overhead of the USA model of healthcare funding as every participant (drug manufacturers and hospitals) get all their necessary expenses and reasonable profit covered already with the $800 price.
