The state of Massachusetts requires all post-secondary institutions to ensure that students are
immune to a number of vaccine-preventable communicable diseases. For UMass Lowell, the process
begins when each student enrolls at the University. At that time, the Registrar's Office
automatically places an Immunization Hold (IMM) on each student's SIS account. This hold is set to
become active at the end of the add/drop period of the student's first semester at the University.
At that time, the student's enrollment status, e.g. day school, online, full-time or part-time, is
established. Students who are registered for ONLY online courses are NOT required to have an
immunization record on file. Their holds will be removed in a batch process by the Registrar's
Office.
