[Evaluation of the vaccinal protection against rinderpest in Cameroon. I. Province of Adamaoua].

As a part of the panafrican rinderpest campaign, a serological survey of 5,720 samples was undertaken in the Adamaoua province of Cameroon. The herd immunity level varied from 60 to 73% in the four departments investigated. Vaccination of all animals from the age of six months, replacement of vaccination equipment, restoration of crushes, and use of magnesium sulfate, or as a substitute, saline for lyophilized vaccine reconstitution are recommended.
