Jake Baggott, associate vice chancellor & executive director of University Health Services, said UW-Madison has directly notified around 4,000 people who may have been exposed. Speaking to reporters on Monday, Baggott said immunization data voluntarily reported by students shows many are already protected against the virus.
“We estimate, based on our own data, that about 95 percent of our campus is vaccinated against measles, which is a good place to be,” Baggott told reporters.
