COVID-19 and weakened immune systems

2023-11-28 19:12:09.83138+01 by Dan Lyke 0 comments

World Health Network: WHN Science Communications — COVID-19 and Immune Dysregulation, a Summary and Resource

COVID-19 infection has several very concerning effects on the immune system that might easily lead to advantages for other pathogens as well as worse outcomes in COVID-19 reinfections. This immune dysfunction or aging is at least one of the most likely scenarios explaining the recent surges in diseases like RSV, influenza, Strep A, and other infections. By contrast, immunity debt is not considered a viable explanation as the surges of these diseases continue in countries that had surges last season and immunity wanes for many of these diseases. Another serious concern at this point is that repeated infections by COVID-19 might lead to depletion or exhaustion of cytotoxic CD8+ T cells which could have downstream effects on other diseases like cancers, as these T cells are instrumental in limiting tumor proliferation and have been shown to differentiate to become dysfunctional.

We will not edit your comments. However, we may delete your comments, or cause them to be hidden behind another link, if we feel they detract from the conversation. Commercial plugs are fine, if they are relevant to the conversation, and if you don't try to pretend to be a consumer. Annoying endorsements will be deleted if you're lucky, if you're not a whole bunch of people smarter and more articulate than you will ridicule you, and we will leave such ridicule in place.
