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 network with primary interests in the area of vaccine safety and effectiveness. We make it possible for global collaborative retrospective analyses of health data by utilising the existing capabilities of some partners and growing the capacity of countries with less developed data infrastructures.

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 the only organisation that has this level of post-introduction pharmacovigilance study responsiveness or equivalent geographic diversity, population heterogeneity, breadth of subject matter expertise, and database robustness.

The Global Vaccine Data Network™ is a multinational collaboration ready to conduct globally coordinated epidemiological studies on the safety and effectiveness of vaccines, including COVID-19 vaccines.

A coordinated global effort to assess vaccine effectiveness in diverse settings is necessary to get the best outcomes from vaccines.

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 31 collaborating institutions in 26 countries and is expanding.

Through a sustainable network 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.

Vaccines are a great example of the truism that prevention is better than cure.
They are also an exception to the rule that modern medicine tends to be reactive rather than proactive. However, concerns about vaccinating oneself or one's children, vaccine hesistancy, is weakening vaccination programs globally. Rigorous and objective vaccine safety science is critical for vaccine confidence.
