Immunity of nursing students to measles, mumps, rubella, and varicella in Yozgat, Turkey.

Measles, mumps, rubella, and varicella (MMRV) are vaccine-preventable diseases. The aim of this study was to determine the vaccination status of first-year nursing students in Turkey. The sample used was 180 students and immunoglobulin G antibodies against MMRV viruses were determined quantitatively by enzyme-linked immunosorbent assay. Immunity rates to MMRV were 82.8%, 83.3%, 98.3%, and 100%, respectively. The results of this study showed that all of the students were immune to varicella and 32.8% of the students were not immune to at least 1 of the viruses covered by the measles, mumps, and rubella vaccine.
