Vidcast:  https://youtu.be/QNayV-DKu-w   Patients in critical condition due to CoVid19 infection develop the most intense cell-mediated immunity against the virus.  A German analysis of 28 CoVid patients defines the nature of anti-viral killer immune T cells.   The greatest numbers of the most toxic virus killer T cells arise in the sickest CoVid patients.  While it is good news that the human immune system reacts to the virus by producing immune lymphocytes as well as antibodies, it is this very reaction that provokes a cytokine storm creating collateral damage to the lungs, heart, and kidneys.   This new information will help clinicians develop vaccines that prevent viral invasion and hyperimmune devastation.   https://www.medrxiv.org/content/10.1101/2020.05.13.20100636v1.full.pdf   #covid #pandemic #cellmediatedimmunity #tcells #cytokinestorm
