Sociological theory and intervention in Public Health. A study on vaccine hesitancy

This study deals with the design and implementation of public health interventions in relation to vaccine hesitancy. The main objective, based on a literature review (LR), is to find answers to two questions regarding public health interventions: a) the usefulness of theory for the design of public health interventions and b) the applicability of theory to interventions. Therefore, the study examines theoretical approaches, context and complexity of interventions; discusses specific theories such as Actor-Network Theory, Social Worlds Theory and Normalisation Process Theory and argues the application of theories to established intervention models.
