Summary
This study tests whether changing how people interact in online social networks can improve their attitudes and intentions toward COVID-19 vaccination. Over 4,400 adults in the US with internet access will be placed into different online groups and answer health questions while seeing feedback from others. The goal is to see if less centralized and more diverse networks help reduce vaccine hesitancy and health inequities.
