This memorandum serves to inform you that the Canadian Centre for Veterinary Biologics (CCVB), Canadian Food Inspection Agency, will consider requests for a waiver to the target animal batch safety test (TABST) for inactivated and live veterinary vaccines licensed in Canada.

Background

The International Cooperation on Harmonisation of Technical Requirements for Registration of Veterinary Medicinal Products (VICH) Steering Committee recently finalized guidelines "Harmonisation of Criteria to Waive Target Animal Batch Safety Testing for Inactivated Vaccines for Veterinary Use" (VICH GL 50) and "Harmonisation of Criteria to Waive Target Animal Batch Safety Testing for Live Vaccines for Veterinary Use" (VICH GL 55).

The target animal batch safety test (TABST) for inactivated or live veterinary vaccines is normally performed by administering an overdose of each batch or serial of the vaccine to the intended target species by the recommended route in accordance with the Canadian Health of Animals Regulations, Section 120.4(1)(e) or similar regulatory framework, and Section V.B of the approved Outline of Production. Testing is required for each batch or serial and, as such, veterinary vaccine manufacturers use a significant number of animals. The VICH guidelines outline a process by which the TABST may be waived for a veterinary vaccine meeting specific criteria and, thereby, reducing the use of animals.

The Canadian Centre for Veterinary Biologics is committed to the 3Rs (replacing, refining and reducing the number of animals in testing) and has adopted these VICH guidelines for implementation in Canada.  The CCVB will consider a request for a waiver to the TABST for fully licensed veterinary vaccines with a documented history of safe use.

Applying for a Waiver to the TABST

The CCVB will consider requests for a waiver if the following are met:

  1. The product has a documented history of acceptable safety.
  2. The product is manufactured and tested following recognized quality principles in a consistent and appropriate manner.
  3. The product is manufactured from approved master seed and/or cell stocks in a seed lot system.

Canadian and Foreign, Non-U.S. Manufactured Vaccines

Requests for waivers to TABST will be reviewed on a product-by-product basis. Each request for a waiver to the TABST should include the following information:

U.S. Manufactured Vaccines

For veterinary vaccines manufactured by a U.S. manufacturer and fully licensed for use and distribution in Canada the CCVB will recognize waivers to the TABST issued by the USDA Center for Veterinary Biologics as per USDA Veterinary Services Memorandum No. 800.116.

Canadian Manufactured Vaccines, For Export Only

A request for a waiver to the TABST for a Canadian-manufactured vaccine, licensed for export only, must first be granted by the importing country's regulatory authority. The application package should include the following information:
