The problem with vaccines in the US was they were and still are a low margin business. And it's a low volume business. Couple of million doses a year. Doesn't take that many bogus or maybe not bogus product liability lawsuits to eat all the profit. Faced with drug companies exiting the business Congress set up a separate compensation system for vaccine injuries. I think drug companies pay into a fund that then gets disbursed to people harmed by vaccines. Guiding idea is to keep these cases out of ordinary courts where judges and juries aren't competent and into the hands of a panel who are competent. That way injured people are compensated and drug companies liability is limited.
