NC3Rs | 20 Years: Pioneering Better Science

Workshop: Implementing the 3Rs in WHO biologicals guidelines


Registration Details

London & online

At the culmination of a three-year project to promote harmonised integration of the 3Rs in the World Health Organization (WHO) guidelines for quality control and batch release testing of vaccines and biological therapeutics, we are organising a final international stakeholder meeting in London. This two-day symposium will take place on 19–20 September in central London as a hybrid event with live streaming. 

This project sought to identify animal tests that are currently recommended for batch release testing of biologicals and to propose revisions to promote the use of more scientifically robust 3Rs approaches wherever possible, for implementation by WHO through the Expert Committee on Biological Standardization.


The meeting is free to attend, but registration is essential. We welcome participants from all over the world to better inform the wider community of the recommendations, the rationale for their making and to support future global harmonisation in the adoption of 3Rs approaches. 

Participants joining remotely will be able to watch all presentations and pose questions. However, we encourage you to attend in-person, where possible, to take advantage of the excellent networking opportunities. Please note that there are limited places available for the in-person event. 

For online registrants, certificates of attendance are available on request only to registered participants attending through their unique Zoom link. 

The deadline for registration is Tuesday 12 September.
