Abstract
SmithKline Beecham Biologicals produces two vaccines against hepatitis: hepatitis B (Engerix-B) introduced in 1986 and hepatitis A (Havrix) introduced in 1991. Using these two examples, we demonstrate the long and gradual transition process towards an in vitro release test for potency and a significant decrease in the number of animals needed for vaccine release.
