The Vaccine Safety Net is a network of websites aiming at facilitating public health authorities, health care professionals and the public to reliable information on vaccine safety on the Internet. After more than a decade of remote collaboration, VSN members will meet in WHO headquarters in Geneva, on the 28 and 29 November 2016 to review the past decade of their VSN membership, share their views and experiences, express their expectations for the future of the network and plan next steps.
616 million is the number of visits accounted for a period of six months for a subset of 22 network’s members: by collecting and analysing web analytics at the level of the Network, by understanding the behaviour and needs of websites users, VSN members could work together on defining data driven information and communication strategies for vaccine safety, thus addressing vaccine hesitancy.
In 2013, WHO revised the methodology for causality assessment of individual Adverse Events Following Immunization (AEFI). The new method proposed by WHO was published in the WHO User manual for the revised WHO classification for causality assessment of AEFI. It uses a paper based tool that allows evaluators to review AEFI cases and guide them on their causality.
A companion electronic software application of the tool is now available for computers, IPads and tablets. The software provides step by step guidance in the assessment and reduces the chances of making errors. This tool will facilitate use of the revised methodology and help conducting research.
E-learning course on Vaccine Safety Basics
As part of its mandate of building, maintaining and strengthening capacity for vaccine pharmacovigilance, the WHO developed an online course addressed to health professionals. This course addresses the origin and nature of adverse events following immunization and at promoting good communication practices in handling risks and crises situations. Its content, compiled by international vaccine experts, takes on account different national contexts and is available in 4 different languages. Broad dissemination of this course is encouraged for building a common core knowledge base of vaccine safety issues, and for improving vaccine safety practices in countries in a cost effective manner.
At the request of the MoH Pakistan, WHO organized an AEFI surveillance and monitoring workshop in Islamabad from 23rd to 26th August 2016. The 27 participants included professionals from the Drug Regulatory Authority of Pakistan, the National Program on Immunization and Pakistan Paediatric Association.
