Mean age was 9.17±1.53 years and multistage sampling was performed. Standardized interviews obtained information on each child`s reported (by parents) immunization status and documentary evidence of immunization was recorded from the Personal Health Record. Rubella Virus antibodies were measured by the quantitative chemiluminescent method. Sufficient blood for antibody testing was obtained from 1665 children, 975 (57%) were girls and 720 (43%) were boys, respectively . On the whole, 541 subjects (32.5%) had been vaccinated and 1124 (67.5%) had not been vaccinated at all. Among those vaccinated, 205 (38%) were seropositive and 336 (62%) were seronegative, respectively. Among those unvaccinated, 328 (29%) were seropositive and 796 (71%) were seronegative. Rubella immunization rates in Tehran are relatively low and most of these immunizations are provided by the private sector. Results indicated that the immunity produced by the rubella vaccine is not long-term. Thus rubella vaccination of infants does not decrease congenital rubella and it seems that the most certain time at which vaccination should be done to prevent congenital rubella syndrome, is premarital age in females.]]>Amin, Z., M.A. Naphisi, K.
