Vaccine coverage, timeliness and delay estimated from regional and national cross-sectional surveys in Ethiopia, 2016.

Introduction: measures of vaccine timing require data on vaccination dates, which may be unavailable. This study compares estimates of vaccine coverage and timing; and compares regression techniques that model these measures in the presence of incomplete data.

Methods: this cross-sectional study used the 2016 Ethiopian Demographic and Health Survey (DHS), and a 2016 survey from Worabe, Ethiopia.
