A bill for an act relating to liability for injuries caused by vaccines.

HF 712 requires vaccine manufacturers to waive legal protection under federal law (42 U.S.C. §300aa-1 et seq.) before distributing, selling, or administering vaccines in Iowa. This bill directly affects vaccine manufacturers operating in Iowa, as they must affirmatively give up immunity from lawsuits for injuries caused by vaccine design defects. The key mechanism is a mandatory waiver: if a vaccine is distributed in Iowa, the manufacturer is deemed to have waived federal immunity for design defect claims, overriding the National Childhood Vaccine Injury Act. The bill does not change liability for other vaccine issues like manufacturing errors.
