The Missouri House gave first round approval Wednesday to a bill that takes aim at mercury in vaccines. KSMU's Missy Shelton reports.
The proposal would prohibit children from receiving vaccinations that contain mercury.
It also would require doctors to inform adults if they're going to receive a vaccine that contains mercury.
Bill supporters say mercury poisoning appears to be connected to autism.
