Results and Policy Implications of a COVID-19 Vaccine Post-introduction Evaluation in Thailand, May 2022

Abstract

Thailand initiated a COVID-19 vaccine campaign in February 2021, and by March 2022, approximately 72% of residents over 5 years of age had received two doses of vaccine. We evaluated Thailand’s COVID-19 vaccine campaign in Bangkok and in four additional provinces using the World Health Organization COVID-19 post-immunization evaluation (cPIE) protocol. Strengths of the vaccine program included close coordination between different levels and sectors of the Royal Thai Government, close community engagement, and use of national data systems. Areas of the campaign that needed interventions included reviewing cold chain practices, standardizing data forms and addressing bottlenecks in data systems.
