School Immunization Levels in Contra Costa County


To prevent disease outbreaks in a community, at least 90% of its population must be immunized ("community immunity"), depending on the disease. When parents choose not to vaccinate, they put their children, and our community, at greater risk of severe, vaccine preventable diseases.

The searchable maps below show the location of every licensed preschool and child care center in Contra Costa County with 15 or more students, and every grade school that enrolls 15 or more kindergarteners. Each school is color coded according to the percentage of enrolled students in 2014-15 that lack one or more required immunizations because their families filed Personal Belief Exemptions (PBEs). The countywide PBE level is less than 3% but some schools have much higher levels.

  •  Highest risk (more than 10% of students not immunized because of Personal Belief Exemption)
  •  Greater risk (3% to 9.9% of students not immunized because of Personal Belief Exemption)
  •  Lowest risk (0% to 2.9% of students not immunized because of Personal Belief Exemption)
