October 20th, 8:00 PM: "Coronavirus Versus the Human Immune System"

Most of the time we don't think at all about our immune system, but last Spring almost everybody realized how important this unheralded system is to each individual's day-to-day survival. The disease caused by SARS CoV-2 received saturation coverage for months both in mainstream media and scientific literature. The human immune system is exceedingly complex and, not surprisingly misinformation entered into the massive amount of news about this viral outbreak. My objectives are to discuss some of the misinformation and present a few of the many principles and components of the human immune system to help you better appreciate the continual war between Man and microbes.
I've followed this current viral outbreak from the beginning and have read 2-3 papers every day since last winter, in addition to two books on immunology and one on viruses. This is your chance to understand what you have seen and heard about the Coronavirus and the human defenses against it.
