Antimeasles antibodies in children submitted to different vaccination schedules.
In order to study the measles antibody behavior of three vaccination schedules, 684 children were divided into 4 Groups: Group A (341 vaccinated children under the age of one); Group B (101 children at the age of one); Group C (74 children under the age of one and one at the age of one); Group D (163 unvaccinated children with a history of measles in the past-Group control). Children of Group A presented lower rates and 25.9% of the age group under two did not show any measles antibodies. In Group B, all the children presented antibodies. In Group C only 4.0% did not. In all age groups, the geometric mean HI antibody titers of Group A were lower than the values found in the other groups. The age at vaccination was the factor of greater influence on the results of this study.
