San Diego, CA, August 29, 2026 — California health officials have confirmed that the state will continue to enforce its current school vaccination requirements. This decision applies to all mandated immunizations for students attending educational institutions, including those for measles, mumps, and rubella (MMR).

The state’s position remains firm despite a federal executive order that has proposed alterations to the national childhood vaccine schedule. State health authorities have emphasized that California possesses the independent authority to establish and maintain its own immunization mandates for school attendance. This regulatory power has been previously affirmed by legal challenges.

A recent ruling by a federal court further solidified California’s authority, blocking similar attempts to modify vaccination requirements at the federal level. This judicial decision supports the state’s right to set its own public health standards for its student population.

This stance by California comes at a time when public health experts are observing a national uptick in measles cases. Concurrently, data indicates a slight decline in overall vaccination rates within California, a trend that health officials are monitoring closely.

The existing California school immunization requirements are designed to protect students and the wider community from vaccine-preventable diseases. Mandates typically require proof of vaccination for specific diseases before a child can enroll in public or private schools, and some types of childcare facilities.

Specific details regarding the federal executive order’s proposed changes to the childhood vaccine schedule were not immediately available, nor were the names of the state health officials who made the announcement or the specific federal court that issued the ruling. The exact percentage of the decrease in California’s vaccination rates was also not provided.
