European stakeholders face significant variability in addressing vaccination hesitancy and implementing COVID-19 vaccination campaigns among healthcare providers and the general population. Challenges include widespread hesitancy within the population and variations in the communication skills of healthcare providers. To address these issues, cross-country initiatives play a crucial role in knowledge-sharing, especially considering the observed differences in vaccine coverage during the COVID-19 pandemic.

The co-OPERATOR project seeks to capitalize on research findings by developing and piloting a knowledge hub, virtual observatory, and training system across participating countries and beyond. This proof-of-concept initiative aims to gather, structure, and disseminate knowledge, best practices, and resources related to stakeholders’ strategies for COVID-19 vaccination and beyond. The primary focus lies in advancing communication and knowledge skills while addressing systemic barriers and facilitators for effectively promoting vaccination messages to the population.
