Republicans reject Democratic attempts to tighten vaccine laws

Democrats in six states — Colorado, Arizona, New Jersey, Washington, New York and Maine — have authored or co-sponsored bills to make it harder for parents to avoid vaccinating their school-age children, and mostly faced GOP opposition. Meanwhile in West Virginia and Mississippi, states with some of the nation’s strictest vaccination laws, Republican lawmakers have introduced measures to expand vaccine exemptions, although it’s not yet clear how much traction they have.

In Washington state, which has one of the biggest measles outbreaks, a bill in the state Senate to narrow vaccine exemptions passed through the health committee without the support of a single Republican. The same thing happened in legislative committees in Colorado and Maine over the past week.

All states have mandatory vaccination laws, but they vary in how liberally they dispense exemptions on religious or philosophical grounds. That’s getting scrutiny as measles spreads.
