California would allow children age 12 and up to be vaccinated without their parents' consent, the youngest age of any state, under a proposal by a state senator. Alabama allows such decisions at age 14, Oregon at 15, Rhode Island and South Carolina at 16, according to Sen. Scott Wiener, a Democrat from San Francisco who is proposing the change. Only Washington, D.C., has a lower limit, at age 11. Wiener argued that California already allows those 12 and up to consent to the Hepatitis B and Human Papillomavirus (HPV) vaccines, and to treatment for sexually transmitted infections, substance abuse and mental health disorders. Currently, in California, minors ages 12 to 17 cannot be vaccinated without permission from their parents or guardian, unless the vaccine is specifically to prevent a sexually transmitted disease. Wiener's bill would lift the parental requirement for that age group for any vaccine that has been approved by the U.S. Food and Drug Administration and Centers for Disease Control and Prevention.
