The University of California follows the recommendations of the California Department of Public Health (CDPH) Immunization Branch for Colleges and Universities. The current requirements reflect those in place on February 24, 2016. However, UC reserves the right to modify these requirements pending revisions to the recommendations by CDPH. Changes in CDPH's recommendations will be incorporated into the requirements affecting the incoming fall class each year.
The University of California requires vaccines because of the increase in outbreaks of vaccine-preventable illnesses over the past five to ten years, and many illnesses which we thought were disappearing are returning. Although many of these diseases are considered “mild," they can cause serious illness and death. Pertussis was responsible for hospital stays for hundreds of people in California, including intensive care admissions and in a few cases, death. Outbreaks of measles also resulted in hospitalizations, and new cases of mumps across the country threaten the health and fertility of non-immune students.
