I sure am glad that you agree that when someone has a severe adverse reaction and has a life changing event that they should not get support or compensation from the billion dollar companies.
This is standard practice for vaccines and has been for decades. They're usually ordered by the government, and unlike most medications, it's (usually) a one and done deal, or at the very most, highly periodic, like once a year for the flu vaccine. Companies couldn't even amortize their development costs much less actually turn a profit if they released some vaccine with unexpected side effects because of the often time-critical nature of developing them.
This has been the case since the National Childhood Vaccine Injury Act (1986). Although specific immunities had been granted prior to then, this made it the standard practice that vaccine litigation is essentially not allowed.
This doesn't mean people injured by a vaccine aren't entitled to compensation, but it is generally not directly from the corporation, but from a general fund earmarked for the purpose, since pretty much any vaccine has some chance, usually small, of adverse effects.
I personally don't trust this process for this particular vaccine because of the politics of it, but it's generally worked, if keeping vaccines getting manufactured is important. Nobody would bother manufacturing them if utter ruination would result from a bad batch, never mind some thalidomide level catastrophe.
This is not unique to vaccinations. It is a fairly common resolution to highly complex mass torts litigation, e.g., the September 11th Victims Compensation Fund and the Asbestos Trust Funds, both of which have immense legal bureaucracies to operate. Instead of filing suit against a specific defendant, the claimant has to show exposure to harm entitling them to compensation, and then navigate a complex grid of harms caused to them, such as personal injury from 9/11 or having mesothelioma.
This is why you see so many mesothelioma lawyer ads, Roundup lawyer ads, and the like. Your clients all start out already presumptively owed money and you can go straight to milking the cash cow.
