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), Meningitis, and a Tdap vaccine in place of a tetanus and diphtheria toxoids (Td) vaccine. A tetanus booster is required every 10 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 Influenza vaccine 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.
