摘要:There are few published reports on epidemiological studies concerning Rubella in Iran. The level of antibody in vaccinated individual’s declines gradually and the chances of infection in these people are much greater to those naturally immunized by infection. Therefore, it seemed logical to determine the level of antibody in non vaccinated female students, aged from 18 to 26 years of Isfahan University, to know the degree of their susceptibility to infection. The results of antibody titration revealed that in this age group the level of antibody was high enough to prevent infection.
