Immunization requirements The Massachusetts Department of Public Health requires that all students be immunized for attendance at school. The only exceptions are for documented religious or medical reasons. Failure to meet immunization requirements can result in a student's exclusion from school until the requirements are met. Immunization requirements for the high school as of September 1, 1999 are as follows:
4 or more doses of DPT (Diphtheria, Pertussis and Tetanus) with a booster 5 years later (usually before 7th grade) and subsequent boosters every 10 years. 4 doses of OPV (oral polio) unless the third dose was given after the fourth birthday, in which case only 3 doses are required. 2 doses of MMR (Measles, Mumps and Rubella) 3 doses of Hepatitis B 3 doses of Hib 1 dose of varicella or documentation of disease (chicken pox)
