Cost-effectiveness analysis of an additional birth dose of Hepatitis B vaccine to prevent perinatal transmission in a medical setting in Mozambique.

This study is the first to assess the cost-effectiveness of an additional birth dose of Hepatitis B (HBV) vaccine administered by professional birth attendants in medical settings in a sub-Saharan country (Mozambique). The WHO has recommended the birth dose to prevent perinatal transmission of HBV. A Markov model was constructed to analyse the costs and effects associated with avoiding perinatal transmission of HBV through a birth dose vaccination in addition to the existing vaccination schedule in Mozambique.
