A reminder has been issued to parents that their children must have the proper immunizations before returning to school or college in Baltimore County.

Children starting kindergarten or first grade must have had vaccinations for hepatitis B and chickenpox. That is in addition to immunization for diphtheria, tetanus, measles, mumps, rubella (German measles) and polio, according to the Maryland Department of Health and Mental Hygiene.

Parents of college-bound students living on campus must show proof of vaccination for meningitis or have a signed waiver indicating that he or she chose not to receive the shot.
