Adventitious agents in viral vaccines: Lessons learned from 4 case studies

Since the earliest days of biological product manufacture, there have been a number of instances where
laboratory studies provided evidence for the presence of adventitious agents in a marketed product.
Lessons learned from such events can be used to strengthen regulatory preparedness for the future.

Four case studies where an adventitious agent, or a signal suggesting the presence of an agent, was found in a viral vaccine, are presented in this paper. The lessons learned from each event are discussed.

Based in part on those experiences,certain scientific principles have been identified by WHO that should be considered in regulatory risk evaluation if an adventitious agent is found in a marketed vaccine in the future.
