Identification and immunization of medical students susceptible to measles and rubella: a nationwide survey.

Responses to a questionnaire regarding student immunization from 101 of 129 allopathic medical schools (78.3 per cent) indicated that 16 schools (15.8 per cent) do not request historical information or perform serologic tests on their students. Only 47 of 85 schools (55.3 per cent), who do screen students, utilize antibody titers.
