This study examines the lack of confidence in the actions of the government and pharmaceutical companies during vaccine deployment. The authors introduce the concept of supply chain immunity. The authors test whether the perception of higher vaccine supply chain immunity leads to higher willingness to be vaccinated within the supply chain community.
The authors utilize factor analysis and item response theory methods to develop a scale for measuring supply chain immunity. The original and psychometrically sound scale is tested via a structural equation model (SEM). Factor analysis and SEM use survey responses from two samples of 125 supply chain executives.
SEM suggests that supply chain immunity perceptions are a strong predictor of overall supply chain confidence for COVID vaccines. Further, these perceptions, through supply chain confidence, indirectly impact individuals' self-reported willingness to personally accept a vaccine themselves.
This paper presents the concept of supply chain immunity perceptions that have not been used in the medical supply chain literature. This paper presents a first-of-a-kind scale for supply chain immunity perceptions utilizing nascent methods and demonstrates the constructs impact on vaccine program confidence and public willingness to participate.
