Prior to 2021 and the COVID-19 pandemic, American Democrats led the anti-vaccine movement. They couched it in anti-corporate terminology and that let politically allied academics and journalists turn a blind eye to the harm their thinking caused. In 2015, after a decade of effort by Science 2.0 and many others, California passed a law banning 'philosophical' objections, a haven that had only been used by fringe religious groups before the 1990s, but in California had led to more un-vaccinated children on the coasts, in places like Berkeley, Los Angeles, and Marin County, than the entire rest of the United States combined.It was a struggle to educate parents that vaccines were safe and necessary when they instead believed in supplements, organic food, and solar power.
