Map: MMR and full vaccination rates in California kindergartners

This interactive map shows kindergartners’ vaccination rates at more than 6,000 public and private schools across California. According to the state health department, at least 95% of students need the MMR (measles, mumps, rubella) vaccine to maintain herd immunity and prevent outbreaks. Yet in many parts of the state — including areas around Sacramento, Oakland, the Central Valley, and Los Angeles — vaccination rates fall short of that threshold, raising concerns about community vulnerability.
