Objective 1

To build survey tools to measure the determinants of vaccine uptake (general population) and of skills for promoting vaccination programmes efficiently (healthcare professionals).

Objective 2

To develop a set of citizen-centred evidence- based, scientifically sound recommendations and advice on how to address low vaccination uptake and to help healthcare professionals communicating more efficiently about vaccines.

Objective 3

To provide a comprehensive assessment of factors underlying low vaccination uptake and healthcare professionals’ barriers and facilitators to communicate vaccination information as well as their distribution among target population groups to inform a citizen-centered approach to promote vaccination uptake.

Objective 4

To design and develop an intuitive and interactive virtual observatory (the co-OPERATOR platform) to foster dissemination, transferability, utilization of project results across the participating member states, the EU/EEA and beyond.

Objective 5

To translate research evidence generated by other WPs into evidence-based recommendations (intervention toolset) by engaging with stakeholders through a Policy Lab to address barriers and knowledge gaps and co-create practical solutions for implementation at regional, national, and European level.
