Relating to the liability of vaccine manufacturers that advertise a harmful vaccine.

HB 3441 creates legal liability for vaccine manufacturers who advertise a harmful vaccine within Texas. It defines "advertise" broadly to include paid promotions across media (TV, internet, influencers), but excludes doctor-patient discussions or clinic materials. If a manufacturer's advertised vaccine causes injury, victims can sue within three years for actual damages, attorney fees, and court costs. The law applies only to cases where harm occurs on or after its effective date of September 1, 2025.
