So some bacteria can avoid our immune system whereas others can fight them off. TB is quite special, in that it causes a huge immune response, but this immune response really doesn’t do much to stop TB, so our bodies form a thing called a granuloma to try to contain the bacteria. Bacteria have been around for a long time and have got super good at making us sick and avoiding out immune system!
