The Brief California public health officials are urging families to ensure children receive all required immunizations before the upcoming school year begins. As the upcoming school year approaches, public health officials are urging families to prioritize obtaining all required vaccinations for their children. California rejected those rollbacks and continues to enforce its own standards through the California Department of Public Health, as states retain authority to establish individual vaccine policies. For example, the San Francisco Department of Public Health recommends tuberculosis screening for students entering a new school following a tuberculosis outbreak at Archbishop Riordan High School last year. "It's especially important in school where children are together," said Dr. Dean Blumberg of UC Davis Health.
