Regional Disparities in Measles Vaccination Coverage and Their Associated Factors: An Ecological Study in Japan.

ABSTRACT:

Background

The decline in measles vaccination coverage is a global concern. In Japan, coverage of the first dose of measles vaccine, which had exceeded the target of 95.0% since fiscal year (FY) 2010, fell to 93.5% in FY 2021. Vaccination coverage increased to 95.4% in FY 2022 but varied by municipality. Few studies have focused on regional disparities in measles vaccination coverage. This study aimed to clarify the regional disparities in measles vaccination coverage by municipality in Japan and their associated factors.

Methods

In this ecological study, the measles vaccination coverage in FY 2022; population density; area deprivation index (ADI; an indicator of socioeconomic status); proportion of foreign nationals, single-father households, single-mother households, and m
