Shifting Vaccination Politics — The End of Personal-Belief Exemptions in California — NEJM
by Michelle Mello, David Studdert, Wendy Parmet
It's not often that California, West Virginia, and Mississippi are politically aligned, but that unlikely trio formed on June 25, 2015, when California Governor Jerry Brown signed into law Senate Bill (SB) 277, substantially narrowing exceptions to school-entry vaccination mandates. With that law, California becomes the third state to disallow exemptions based on both religious and philosophical beliefs; only medical exemptions remain. The move represents a stunning victory for public health that affects not only California schoolchildren but also the prospects for strengthening vaccination requirements nationwide.
