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.
