1.1 Field trials are real-life experiments which test directly whether proposed interventions actually work. This makes them powerful tools for gathering evidence for making policy. But, as with all research methods, they come with costs, such as time and resource.
Community trials address the efficacy of preventive interventions applied at the group level (e.g., a social marketing campaign trial). Field trials address preventive interventions applied to individuals (e.g., a vaccine trial).
