Immunization, Vaccines and Biologicals

Validating information on vaccine safety

When people need advice about topics like health or careers, the first place they often look is the internet. The same is true when parents and caregivers are seeking credible information about whether vaccines are safe for their children.

WHO’s Vaccine Safety Net — a global network of vaccine safety websites — provides access to accurate and trustworthy information about vaccines.

Today, the network has 47 member websites in 12 languages. It is estimated that more than 173 million users every month access VSN websites.

Commentary: Reaching everyone, everywhere with life-saving vaccines

In 2015, world leaders agreed to a new development plan—a set of Sustainable Development Goals (SDGs) and expanding access to immunisation is crucial to achieving the SDGs. Not only do vaccinations prevent the suffering and death associated with infectious diseases, they also help enable national priorities like education and economic development to take hold.

IImportant progress have been made towards the Global Vaccine Action Plan, endorsed at the World Health Assembly in 2012, including more children being immunized worldwide, more countries are introducing new or underused vaccine, new vaccine against dengue has been licensed in several countries, and the first vaccine to protect children against malaria will be piloted in three African countries in 2018.

Yet major challenges remain.
