Hepatitis B virus (HBV) infection amongst children in Senegal: current prevalence and seroprotection level

Abstract

Our results suggest that although HBV prevalence has significantly decreased in children in Senegal following a better HBV vaccine coverage, the number of children correctly seroprotected is insufficient (56%). Assessing the levels of HBsAb and providing HBV vaccine boosters should be considered in children in Senegal.
