New Year’s Day 2016 was more than a day to make resolutions. In California, Senate Bill 277 took effect, under which only medical exemptions to required immunization will be allowed for students entering school after January 1, 2016. California no longer permits immunization exemptions based on personal beliefs for children in childcare and public and private schools. The language of SB 277 is available on the California Legislative Information website.
