Immunity: How T Cells And B Cells Fight Infections

nature (March 15, 2023) – Lymphocytes are immune cells that play vital roles in fighting infections. The most well-known lymphocytes are the T cells and B cells of the adaptive immune system. In the 1950s and 1960s, scientists performed experiments to follow lymphocytes on their journey around the body, which helped us to work out where they go and what they do.

This work laid the foundation for everything we know about T cells today, including how they become activated to fight infections and how they form memory populations that provide long-lasting immunity.

Understanding how the body clears the new coronavirus is becoming more important as the U.S. begins to reopen. WSJ’s Daniela Hernandez explains how the body fights infection and why feeling better doesn’t equal being virus-free. Photo illustration: Laura Kammermann


This excellent video is well worth watching and listening to. It revisits how the immune system, both innate and adaptive responds to SARS CoV and other viruses.

It shows graphically how long the body takes to clear the the Covid 19 virus.

And it makes me, a susceptible 88 year old, even more alert to infection. We should keep our guards up.

Even if an effective vaccine is found, it will probably take its place, incorporated into influenza vaccine as an annual immunization.
