VICH Public Consultation on guidelines relating to efficacy of anthelmintic products

As an Observer Member of VICH (the International Cooperation on Harmonisation of Technical Requirements for Registration of Veterinary Medicinal Products), we are inviting comments through a public consultation on proposed revisions to existing guidelines relating to the technical requirements for demonstrating efficacy of anthelmintic products in different animal species.

In addition to the general requirements, recommendations for bovines, ovines, caprines, equines, porcines, canines, felines, and poultry are being revised.

The proposed draft documents are published at Draft Guidelines for public consultation ( and the consultation remains open until 1 November 2022.

Comments should be relevant to these specific guidelines, and can either be general on the approach outlined or comments on the actual text of the guideline.
