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 laboratory animal batch safety test (LABST) for 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 guideline "Harmonisation of Criteria to Waive Laboratory Animal Batch Safety Testing for Vaccines for Veterinary Use" (VICH GL 59 - PDF (385 kb)).

The laboratory animal batch safety test (LABST) for veterinary vaccines is normally performed by administering a proportional dose of each batch or serial of the vaccine to mice or guinea pigs 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. Safety testing is required for each batch or serial and, as such, veterinary vaccine manufacturers may use a significant number of animals. The VICH guideline outlines a process by which the LABST may be waived for a veterinary vaccine meeting specific criteria and, thereby, reducing or eliminating the use of animals.

The CCVB is committed to the 3Rs (replacing, refining and reducing the number of animals in testing) and has adopted this guideline for implementation in Canada. The CCVB will consider a request for a waiver to the LABST for fully licensed veterinary vaccines with a documented history of safe use.

Applying for a Waiver to the LABST

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. (United States) Manufactured Vaccines

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

U.S. (United States) 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 LABST issued by the USDA (United States Department of Agriculture) Center for Veterinary Biologics (CVB).

Canadian Manufactured Vaccines, For Export Only

A request for a waiver to the LABST 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:

Exceptions to the Application Process

The CCVB will not consider waivers to the LABST for:
