The bill establishes new provisions regarding the liability of vaccine manufacturers for injuries caused by design defects in their products. Specifically, it mandates that no vaccine may be distributed, sold, or administered in Iowa unless the manufacturer explicitly waives any immunity from lawsuits related to injuries stemming from design defects. This includes immunity protections provided under the federal National Childhood Vaccine Injury Act.

Additionally, the bill stipulates that any vaccine manufacturer whose product is distributed, sold, or administered in Iowa is automatically considered to have waived their immunity to lawsuits for injuries caused by design defects. This legislative change aims to hold manufacturers accountable for the safety of their vaccines and ensure that individuals who suffer injuries have the right to seek legal recourse.
