Seed Lot
Seed Lot System - A seed lot system is a system according to which successive batches of a product are derived from the same master seed lot at a given passage level. For routine production, a working seed lot is prepared from the master seed lot. The final product is derived from the working seed lot and has not undergone more passages from the master seed lot than the vaccine shown in clinical studies to be satisfactory with respect to safety and efficacy. The origin and the passage history of the master seed lot and the working seed lot are recorded.

Master Seed Lot - A culture of a microorganism distributed from a single bulk into containers in a single operation in such a manner as to ensure uniformity, to prevent contamination and to ensure stability. A master seed lot in liquid form is usually stored at or below -70ºC. A freeze-dried master seed lot is stored at a temperature known to ensure stability.
Working Seed Lot - A culture of microorganism derived from the master seed lot and intended for use in production. Working seed lots are distributed into containers and stored as described above for master seed lots
