[The transmission of maternal measles antibodies to newborn infants in the Ivory Coast]

Authors studied the disappearance of mothers measles antibodies among 286 babies from Ivory Coast 250 of which were living in Adzopé, a town with 30,000 inhabitants at 100 km up North from Abidjan and the 36 other babies in Abidjan. The study of antibodies by IHA showed a higher serum incidence rate of mother antibodies among 4 months aged babies in Abidjan. The more sensitive study of antibodies by the Mann serum neutralisation, shows that when 6 months aged, 60% babies from Adzope still have antibodies and when 10 months aged, none of the babies is positive. Serum negativation is late compared to Brazzaville when antibodies level is lower.
