Understanding threats to polio vaccine commitment among caregivers in high-priority areas of Afghanistan: a polling study

Background: Eradication of poliovirus from endemic countries relies on vaccination of children with oral polio vaccine (OPV) many times a year until the age of 5 years. We aimed to determine caregivers' commitment to OPV in districts of Afghanistan at high risk for polio transmission and to examine what knowledge, attitudes, or experiences could threaten commitment. Methods: We designed and analysed a poll using face-to-face interviews among caregivers of children under 5 years of age. The sample was drawn via a stratified multistage cluster design with random route household selection. We calculated the percentage of committed and uncommitted caregivers. All percentages were weighted. We then compared percentages of uncommitted caregivers among those with varying knowledge, attitudes, and experiences, using logistic regression to control for possible demographic confounders. Findings: Between Dec 19, 2014, and Jan 5, 2015, we interviewed 1980 caregivers, 21% of whom were “uncommitted” to accepting OPV.
