The first sign of a problem appeared on Dec. 28, 2014, when an 11-year-old unvaccinated child in California was hospitalized with a suspected case of measles. The child’s only unusual activity had been a visit to one of two adjacent theme parks in Southern California — Disneyland and Disney California Adventure — popular destinations for travelers from countries where vaccination rates are low and measles, a highly contagious and sometimes fatal virus, is endemic.

The largest measles outbreak in California in almost 20 years was about to begin, bringing with it an emotional debate about public health, parental rights and school vaccination requirements.

On June 30, 2015, Gov. Jerry Brown signed legislation creating one of the strictest vaccination laws in the country. The law goes into effect Jan. 1, 2016. Based on EdSource articles and commentaries, the following storyline tracks the debates and legislative actions that have occurred since 2012.
