|
Vaccine confidence will be measured based on participants' scores on the Vaccine Confidence Index included in the study questionnaire, which assesses perceptions of vaccine importance, safety, effectiveness, and compatibility with religious beliefs. Responses to individual items will be scored according to the predefined scoring criteria and combined to generate an overall vaccine confidence score. Higher scores indicate greater confidence in vaccines. |
