Setting Specifications on Potency Assays: • How much do we need? Two Questions • How certain do we need to be of that value? 23
U.L. Potency L.L. Calculation of vaccine minimum release potency •For vaccines, we usually set a minimum release spec to assure mean potency exceeds a clinically acceptable lower limit (L.L.) throughout the shelf life Release spec } Error term Time Expiry } Expected stability loss based on stability studies (linear regression, when feasible)
