Regulatory considerations for emergency use of non-USDA licensed vaccines in the United States.
The Virus-Serum-Toxin Act of 1913 (21 US Code 151-159) provides the legal basis for the regulation of veterinary biologicals in the United States; the United States Department of Agriculture's Center for Veterinary Biologicals (CVB) has the regulatory authority for the issue of licences and permits for such products. The law was intended to establish standards and control the importation of products into the United States and the distribution of products interstate assuring the purity, safety, potency, and efficacy of veterinary biological products. Administrative regulations and standards appear in the Title 9, Code of Federal Regulations, Parts 101-118, with additional programme guidance found in CVB Notices, Veterinary Services Memoranda, General Licensing Considerations, and other guidance documents. Pre-licensing data evaluation procedures are designed to assess the purity, safety, potency, and effectiveness of each product and support all product label claims. To fulfil these criteria, data from all phases of product development are evaluated against these key elements. Under the standard licensing process, this spectrum of evaluation includes complete characterization and identification of seed material and ingredients, laboratory and host animal safety and efficacy studies, stability studies, and post-licensing monitoring of field performance. This comprehensive evaluation may not be possible during the emergence of a new animal disease. While there are no specific regulations addressing the licensing standards of products for an emerging animal disease, there are mechanisms that allow for the availability of products in an emergency animal health situation. These mechanisms include autogenous biologicals, conditional licences, experimental and emergency use authorizations, and the importation of products in use elsewhere in the world. Pre-approved vaccine banks provide an additional mechanism.
