Earlier quoted context omitted.
Already exists: http://www.supremecourt.gov/opinions/10pdf/09-152.pdf [EDIT: Actually this may not be correct (in this case) because LymeRix was a voluntary vaccination.]
The tl;dr is that in the US, vaccine manufacturers have no liability for the vaccines they produce and sell. Vaccine injury claims are heard without a jury, and paid out by a special fund which exists due to a per-dose tax on vaccines. Vaccinations like the one for Lyme being made unavailable isn't a decision based on liability or risk so much as low demand.
The focus is on compulsory childhood vaccines although the government can add others at its discretion.
