World Health Organization’s Vaccine Safety Net



The Vaccine Safety Net is a global network of websites, established by the World Health Organization, that provides reliable information on vaccine safety. The VSN is a network of a diverse group of digital information resources (websites and social media), VSN members, located in countries around the world and providing scientifically based information on vaccine safety in various languages.




A key player in the Project is the Global Advisory Committee on Vaccine Safety (GACVS), established by WHO in 1999, to respond promptly, efficiently, and with scientific rigour to vaccine safety issues of potential global importance. See GACVS webpage.



At the outset of the Project, GACVS developed three categories of criteria for good information practices – regarding credibility, content, accessibility and design to which digital resources providing information on vaccine safety should adhere. WHO evaluates those electronic resources for their adherence to these criteria.
