> Newsom said the mandate won’t take effect for all children until the U.S. government has finished fully vetting the vaccine for two age groups — 12 to 15 and 5 to 11. That means those in seventh to 12th grades probably will have until July to get their shots. It will be even longer for children in kindergarten through sixth grades because the government has yet to approve any COVID-19 vaccine for that age group.

> California law requires all children enrolled in public and private schools to have 10 immunizations, with exceptions for medical reasons. For the coronavirus vaccine, California will grant exemptions for medical reasons, plus religious and personal beliefs. The rules for those exemptions will be written after the state hears comments from the public. Any student without an exemption who refuses to get the vaccine would be forced to do independent study at home.
