Students at all 10 campuses of the University of California will be required to be screened for tuberculosis and vaccinated for measles, mumps, rubella and other diseases under a new health plan set to take effect in 2017, the university said on Friday.

Announcement of the policy change, which goes beyond the hepatitis B shots already required of all 233,000 UC students, comes amid measles outbreaks that have infected more than 100 people in California and over a dozen more in 19 other U.S. states and Mexico since December.

California public health officials report 103 people have been diagnosed with measles in the state, many linked to exposure to an infected person from outside the country who visited Disneyland in late December.
