Title 21 › CHAPTER 5 — VIRUSES, SERUMS, TOXINS, ANTITOXINS, AND ANALOGOUS PRODUCTS › § 154a
The Secretary can quickly give a special license when there is an emergency, a small market, a local need, or another special situation (including products made only for use inside a State under a State program). That license can include conditions needed to keep the product pure, safe, and reasonably likely to work. The Secretary must make rules that let certain virus, serum, toxin, or similar products be made without a full federal license if they are made: (1) only for use in the maker’s own animals; (2) only for use by a veterinarian in a vet‑client‑patient relationship during state‑licensed veterinary practice; or (3) only for sale inside the State when made under a State licensing program that meets five criteria: the State can license products and makers, review product quality before licensure, check test results before release, enforce violations, and act to prevent worthless, contaminated, dangerous, or harmful products.
