Regulatory considerations for marker vaccines and diagnostic tests in the U.S.
Marker vaccines and diagnostic tests can prove to be invaluable in disease eradication and control programs, as was found in the pseudorabies (Aujeszky's Disease) virus eradication program in the U.S. During that campaign, numerous gene-deleted vaccines and companion diagnostic test kits were used to differentiate infected animals from vaccinated animals, in a strategy that ultimately led to eradication of the disease in commercial swine herds. The United States Department of Agriculture played a key role in delivery of that success by developing biologics policy, evaluating each product, and ensuring that the conditions of licensure were met. What was most critical in the overall eradication effort, however, was the detailed and dedicated interaction among key players: the biologics regulators, manufacturers, Federal, State, and local regulatory partners, veterinary researchers, industry associations, and animal owners. A good disease control program has to include all of these. The regulatory requirements for licensure of marker vaccines and diagnostic test kits are not different from that for other products. There are several mechanisms for vaccine approval, some more rapid than others, but only a few that could apply to these products. Generally, the platforms that might support marker vaccines and companion diagnostic kits are those based on genetic engineering or protein manipulation. If the product is derived from the application of biotechnology, then additional regulatory considerations are applicable. Most important of these are the considerations found in the National Environmental Policy Act (NEPA), wherein deliberate release of any organism containing recombinant DNA into the environment is subject to review and approval by appropriate federal agencies. Environmental release and NEPA compliance are discussed.
