Immunizations against measles, mumps, rubella (German measles), polio, tetanus, and diphtheria are mandatory for all public school children in the District, according to a recent D.C. Board of Education ruling.

In the past, only children entering public schools here for the first time were required to be immunized, and shots for rubella and mumps were not required.

Although officials say children without their immunizations will not be kept out of school this fall, they are encouraging parents to take their children to District health centers for free immunizations, or to their family doctor.

This fall, the Department of Human Resources will begin giving immunizations in the schools, but Dr. Martin E. Levy, chief of the Communicable Disease Control Branch, Community Health and Hospitals Administration, said, "It will take quite some time before we can get through all the schools. I don't think we can do it in one school year." He is encouraging parents to have their children immunized before the shots are available in schools.
