The GVDN uses big data to assess vaccine safety and effectiveness across large and diverse populations around the world and over time.
The Global Vaccine Data Network (GVDN) is a multinational, investigator-led research consortium with primary interests in the area of vaccine safety and effectiveness. We aim to facilitate collaborative studies of vaccine safety and effectiveness using health data from diverse populations in countries around the world.
Vaccine safety and effectiveness research are required to help maximise important health, social, and economic benefits of vaccines. Serious adverse events following vaccination are extremely rare, so it is necessary to study very large populations in order to assess them. With international cooperation, it is now possible to have a large enough population to conduct robust analyses of very rare events following vaccination.




The GVDN is a network of collaborators with capacity in vaccine data linkage supported by a world class coordinating centre. The GVDN currently consists of 23 partners in 18 countries and is expanding.
Through a sustainable consortium that has an agreed governance and participation structure with agreed common data models, vaccine questions can be addressed in a more rapid, efficient, and cost-effective manner than previously achieved.
