COVID-19 vaccine wastage in private and public healthcare facilities in KwaZulu-Natal, South Africa

Abstract

Background: In KwaZulu-Natal (KZN), South Africa, COVID-19 vaccinations commenced in May 2021. This study investigated the extent and reasons for COVID-19 vaccine (C19V) wastage in KZN and strategies undertaken to mitigate loss. Methods: This two-phase multicenter study was conducted at private and public healthcare facilities from May 2021 to July 2022. Results: KZN reported 2% Pfizer and 1% Janssen C19V wasted, mainly due to expiry. C19V waste-minimization strategies reported by 100% public and private sector vaccination leads included cold chain monitoring, designated trained staff and the use of stock-management systems. Conclusions: The WHO’s risk-mitigation factors should be implemented continuously to minimize vaccine wastage.
