[An estimate of the index of collective measles immunity among the pupils in 8-year elementary education in 1988-1989 in sector III of the city of Bucharest].

The authors have verified morbidity antecedents in the medical files of 18.5% of the cohort of 47,354 students registered in classes I-VIII in the year 1988-1989 in the III-rd Sector of Bucharest. On the basis of simple hypotheses concerning the post-infectious anti-rubeola immunity, and the post-vaccinal immunity respectively an index was estimated of the anti-rubeola collective immunity of 89.1% a value associated to the risk of transmission of the rubeola infection in this cohort. These observations have permitted the authors to suggest anti-rubeola vaccination of students without documented evidence of anti-rubeola immunity on the one hand, immediately in all the classes (I--VIII) of the present scholar year, and, on the other hand, to vaccinate all the students in the first class, yearly, as an additional measure in the present control anti-epidemic strategy of rubeola.
