Not sure. The Meses ppl would say that British common law would handle it. Right now drug companies have very few consequences for hurting someone with a vaccine.
Well why is that? If you negligently harm someone that should be a criminal offense. If there're laws that prevent you from being prosecuted, then *that* is the issue, not the concept.
Yup, that's the problem with limited liability corporations. Plausible deniability/guilt distributed over layers of bureaucracy. It's definitely one of the toughest problems we face.
