1907: Get vaccinated or be expelled
"On Tuesday of last week, notices were posted to the effect that all persons connected with the college must either be vaccinated or leave the school by Friday, Nov. 15th. This order was issued on account of the outbreak of several smallpox cases in various parts of the campus, making it appear as though there might be a general outbreak of smallpox over the entire college. Consequently on Wednesday morning there was a rush of students to the hospital to be vaccinated."
