Sera were pretreated with acid washed kaolin and pigeon red blood cell. Titers below 1:10 and in some studies below 1:20 are considered nonimmune to rubella. Our results show that 10, 29% of studied population had HI antibody titer of 10. Considering the results obtained in this study and the fact that the duration of artificial immunity is not fully known, we have discussed different vaccination polices in order to recommend a suitable method for use in Iran. https://ijph.tums.ac.ir/index.php/ijph/article/view/2821 https://ijph.tums.ac.ir/index.php/ijph/article/download/2821/2801
