Nationwide Utilization of Danish Government Electronic Letter System for Increasing InFLUenza Vaccine Uptake Among Adults With Chronic Disease
NCT06030739 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 299881
Last updated 2024-10-10
Summary
In randomized clinical trials and observational studies, influenza vaccination has been shown to be effective in reducing influenza-related illness, hospitalizations, cardiovascular events, and mortality in select populations. However, the real-world effectiveness of influenza vaccination is limited by its uptake. This study will investigate whether digital behavioral nudges delivered via the official, mandatory Danish electronic letter system can increase influenza vaccine uptake among adults aged 18-64 years with chronic diseases.
Conditions
- Influenza
- Behavior and Behavior Mechanisms
Interventions
- BEHAVIORAL
-
