Analyzing the usage of theories of change for routine immunization programs -- a review of impact evaluations from LMICs.

ABSTRACT:

Background

In this article we analyzed the extent of the usage of Theories of Change (TOCs) and causal pathways in the evaluation of immunization programs to identify the challenges to generating evidence on how interventions improve immunization.

Methods

We analyzed the use of the TOC in impact evaluations (IEs) of immunization interventions published after 2010, and its associated articles. The review includes studies from Evidence Gap Map and Yale review that were conducted in May and March of 2020, respectively.

Results

Our review included 47 large-scale and 45 small-to medium-scale interventions. Of the included
