The costs of home delivery of a birth dose of hepatitis B vaccine in a prefilled syringe in Indonesia

Objective To provide global policy-makers with decision-making information for developing strategies for immunization of infants with a birth dose of hepatitis B vaccine, this paper presents a retrospective cost analysis, conducted in Indonesia, of delivering this vaccine at birth using the Uniject prefill injection device. Methods Incremental costs or cost savings associated with changes in the hepatitis B immunization programme were calculated using sensitivity analysis to vary the estimates of vaccine wastage rates and prices for vaccines and injection devices, for the birth dose of hepatitis B vaccine. Findings The introduction of hepatitis B vaccine prefilled in Uniject™ (HB-Uniject) single-dose injection devices for use by midwives for delivering the birth dose is cost-saving when the wastage rate for multidose vials is greater than 33% (Uniject is a trademark of BD, Franklin Lakes, NJ, USA). Conclusion The introduction of HB-Uniject for birth-dose delivery is economically worthwhile and can increase coverage of the
