Kindergarten Vaccination Database

By John C. Osborn

Use this database to find out how many kindergarten students were vaccinated at any public, charter or private California elementary school in the 2015-16 school year. California law mandates that kindergarten students be up-to-date on a number of vaccines that help prevent communicable childhood diseases, such as whooping cough, measles and polio. However, the 2015-16 school year is the last one in which parents will be able to opt out their children from those vaccine requirements for religious or personal reasons after the passage of SB 277 in 2015. Read our answers to "frequently asked questions" about how SB 277 changes vaccine requirements.

Definitions:

  • Opt-out: Refers to students whose parents received exemptions from school vaccine requirements for personal or religious reasons.
  • Medical: Refers to students who are exempt from school vaccine requirements for medical reasons.
  • Conditional: Refers to students who have received some vaccines but under immunization schedules must wait before their next vaccinations. They are admitted on the condition that they become up to date.
  • Up-to-date: Refers to students who are fully vaccinated.
  • Overdue: Refers to students who have not met vaccination requirements and are subject to exclusion from school. The California Department of Public Health began tracking “overdue” students in the 2015-16 school year.
