Towards contextualized complex systems approaches to scaling-up hepatitis B birth-dose vaccination in the African region: a qualitative systematic review.

ABSTRACT:

Background

Despite the longstanding implementation of universal hepatitis B infant vaccination programs, the World Health Organization African region (WHO AFRO) maintains the highest prevalence (2.5%) of chronic hepatitis B virus (HBV) infection among children ≤5 years of age. Scaling-up hepatitis B birth-dose (HepB BD) vaccination could avert mother-to-child transmission of HBV infection and advance regional progress towards eliminating viral hepatitis.

Objective

To describe whether - and how - complexities within the health system or intervention influence the performance of HepB BD vaccination programs in the WHO AFRO.

Methods

Using a complexity perspective, we conducted a qualitative systematic review of literature published between 2009-2022. A Boolean sea
