We will remind you of upcoming deadlines, notify you when we’ll be available for appointments, and send you notifications about your account status.

^this is all the information you need regarding immunization procedure. I contacted CU health services via phone and they informed me that incoming students must fill in the Columbia University MMR Form, which can be found in the link provided above. In addition it is advisable to fax them a copy of your immunization record.
Hope this was helpful!
