The American College Health Association and Centers for Disease Control and Prevention recommend that all students entering college have two doses of the MMR (measles, mumps and rubella) vaccine and a Tdap vaccine in place of a tetanus and diphtheria toxoids (Td) vaccine. A tetanus booster is required every ten years. All incoming students are required to have a tuberculin screening to determine if a TB test is necessary. Northwestern strongly recommends the Hepatitis B series and a Meningitis immunization based on recommendations from the organizations named above. Please refer to the links listed below for further information on these vaccines and discuss your options with your physician.
