Accessibility of pertussis vaccine immunization services in Hubei Province from a supply-demand coupling perspective.

ABSTRACT:

Background

China consistently ranked among the top three contributors to global pertussis cases from 2021 to 2024. However, limited research on the accessibility of pertussis vaccines from a supply-demand perspective has hindered effective control measures.

Methods

A birth cohort-stratified survey was conducted in Hubei Province, China, from March to August 2024. Data on the geographical, awareness-related, and economic accessibility of pertussis vaccination services were collected using electronic questionnaires and field surveys, targeting vaccination staff (supply-side) and caregivers of eligible children (demand-side). Influencing factors were analyzed using the χ² test and univariate and multivariate logistic regression analyses.
