Vaccination rates are up in all but a handful of counties in California, according to data released Tuesday by state health officials. The California Department of Public Health annually reports vaccination data for kindergartners at virtually all public and private schools statewide. For the 2015-2016 school year, 92.9 percent of kindergartners were up-to-date on their vaccines, an increase of 2.5 percent from last year. In California, 2015 was the year of heated debate around vaccines. It started last January with the first reports of a measles outbreak tied to Disneyland. Then, in early February, lawmakers introduced a bill to eliminate the "personal belief exemption" (PBE) which allows parents to refuse vaccines on behalf of their children.
