GONZALEZ-VILLANUEVA, Layda et al. Risk management for changing Working Seed Lots at Finlay Vaccine Institute. Vaccimonitor [online]. 2022, vol.31, n.1, pp. 15-24.  Epub Feb 01, 2022. ISSN 1025-0298.

This article provides a case study of the use of Modal Failure and Effects Analysis to identify and assess the risks of a possible change in the Working Seed Lot at Finlay Vaccine Institute. This analysis took place in one of the critical processes of the Active Pharmaceutical Ingredient Production Plants of the Finlay Vaccine Institute. This analysis did not include changes in the technology for obtaining the Working Seed Lot or changes in the Reference Seed Lot. As a result, eight potential risks were identified and 17 causes were assessed, mainly associated with contamination of the Working Seed Lot or low viability of the Reference Seed Lot, use of raw materials and other materials from unqualified suppliers or after the validity period, handling errors, inadequate operating parameters, use of culture media, contaminated solutions and materials, inadequate operation of equipment and facilities, and untrained personnel.

The identified risks are acceptable, with a low probability of occurrence and are not linked to the safety and efficacy of the active pharmaceutical ingredient or vaccines. Finally, a strategy was proposed that minimizes possible failures in the event of a change in Working Seed Lot for the manufacture of a biopharmaceutical product.
