What phenomenon describes the loss of vaccine potency during transport?
Answer
Potency degradation.
Potency degradation is the process by which a vaccine loses its effectiveness due to poor temperature control or suboptimal handling conditions as it travels through the cold chain. This loss often correlates with the distance from the established electrical grid or the number of transfers required to reach the destination. Each transfer point, such as moving a vaccine from a warehouse to a truck to a small cooler, introduces a potential risk of temperature excursion, meaning that even a successful delivery can result in a vaccine that is less potent than it was at the manufacturing site.
