(Philip Pullman)   1 | Measles and Immune Amnesia 8.5 minutes Measles (MV) is very contagious and can be deadly, even though some cases are mild to moderate. However, it can also "erase" some or all of our immune memory! Measles and Immune Amnesia (article from American Society for Microbiology) Watch: The tricks that make measles so infectious (video you can use in your class) Notes In this segment, the necessary step of memory cells producing effector cells (that engage pathogens) in subsequent exposures to the "remembered" pathogen is glossed over for simplicity of discussion. Presumably, the "live" attenuated MV used in vaccination triggers formation of memory cells against MV without causing the full-blown infection that impairs immune memory of other pathogens.     2 | Sponsored by HAPS 0.5 minutes The Human Anatomy & Physiology Society (HAPS) is a sponsor of this podcast.  You can help appreciate their support by clicking the link below and checking out the many resources and benefits found there.
