Vaccination Confidence Scale
The WHO Vaccination Confidence Scale (VCS) is a multi-domain instrument measuring three conceptually distinct dimensions of vaccine hesitancy: Confidence (trust in vaccine safety and effectiveness), Complacency (perceived need for vaccination), and Convenience (accessibility and practical barriers). Developed by the WHO SAGE Working Group on Vaccine Hesitancy in 2015, it has become the international standard for measuring determinants of vaccination decisions across diverse populations and pathogen contexts.
