Medical groups and a lawmaker behind California legislation to crack down on vaccine exemptions said Wednesday they were surprised by Gov. Gavin Newsom’s last-minute call for changes to the bill, a move that inserted fresh uncertainty into one of the year’s most contentious issues. It was the second time the Democratic governor sought to change the measure aimed at doctors who sell fraudulent medical exemptions for students, a proposal vehemently opposed by anti-vaccine activists. After expressing hesitancy with the bill and winning substantial changes to the measure in June, Newsom had committed to signing it.
