EDUFLUVAC workshop on immunoassay standardisation for universal flu vaccines

The first EDUFLUVAC workshop on immunoassay standardisation for universal flu vaccines took place on 18-19 June 2015 at the National Institute for Biological Standards and Control (NIBSC), UK.  This workshop was co-organised and co-sponsored by the National Institute of Health (NIH) / National Institute of Allergy and Infectious Diseases (NIAID), USA.

Worldwide experts from the universal influenza vaccine research and development field met to initiate discussion on how the community should concentrate its efforts to define the path from immunoassays validation towards harmonisation and ultimately standardisation.  The community agreed that this topic is very critical in the field and that there is a clear need for more collaboration.
