I’m not exactly sure how this would work on a mandate from the governor without legislative approval. Prior required vaccinations are outlined by legislation. Newsom did not announce a legislative intent, but rather a unilateral decree. The teacher’s union controls the leftist political direction in California, so it would appear Newsom is bowing to the demands of the union.
CALIFORNIA – Under the mandate, the COVID-19 vaccine will be added to the list of other compulsory vaccinations required for schooling such as vaccinations against measles, mumps and rubella. Newsom said that parents can claim religious and medical exemptions.
The new mandate will be phased in through two phases: One for children grades seven through 12, and another for kindergarten through sixth grade. The requirement takes effect once the Food and Drug Administration grants full approval for specific age groups, the governor’s office said. The office estimates that children grades seven through 12 will have to be vaccinated by July 2022, while the kindergarten through sixth grade timeline is more nebulous as the FDA has yet to issue even an emergency use authorization for the vaccine for children ages 5 to 11.

The governors office says “suspending the reading, writing and math proficiency requirements … will benefit “Oregon’s Black, Latino, Latina, Latinx, Indigenous, Asian, Pacific Islander, Tribal, and students of color.”
