Reddit mentions of Immunology: A Short Course

There is information available. Go buy and read all the immunology and microbiology textbooks that we learn in medical school.

And then realize that even that is simple compared to the knowledge a pediatrician/infectious disease/gastroenterologist has learned in his/her training. The problem isn't that there isn't information available. It's that it isn't simple enough to be condensed down into one article.
