An exploratory sequential mixed-methods study in Nigeria, Kenya, and Pakistan was conducted aiming to define trust in the context of Childhood, HPV, and COVID-19 vaccines. The Trust Framework was validated by fielding a nationally representative survey of caregivers of adolescents in Kenya and Pakistan. Psychometric properties of the survey and associations between trust and vaccination behaviours were assessed.
