[Serological evaluation of an antimeningococcal mass vaccination campaign in Niger].

Abstract

Authors searched by mean of radio-immuno-essay A and C anti-meningococcal antibodies in two villages from Niger (181 and 92 patients) in a meningitidis endemic area, which one profited 10 months ago of a mass vaccination campaign (A and C polysaccharides). A and C antibodies quantities and percentages of protected patients are not significantly different between the two villages. In one hand anti-C levels increase with patients age. In the other hand, there is a correlation between C meningococcal antibodies and anti-Hbc antibodies.
