   I don’t know the post you’re referring to but I highly recommend How the Immune System Works by Lauren Sompayrac. It explains the interesting parts without getting bogged down in the details of every signalling pathway, but without dumbing things down too much.

   I'd use Abbas' Immunology as a standard textbook and Sompayrac's How The Immune System Works as a more straightforward, lean book on the immune system.

   I've not read it myself, but An Elegant Defense [1] by Matt Richtel has come highly recommended to me. My understanding is that it takes a more human-interest angle, but also does a good job explaining how the immune system works and how it can go wrong at a high level. May be worth checking out as well.

   * Three Body Problem. I've heard of it many times, but never read it. Picked it up a month or two ago, read the whole thing in a few sessions, one of my favourite sci-fi books ever. Will read the next book in the series.

   * Immune: A Journey into the Mysterious System that Keeps You Alive. Best pop-sci book I've read in a while. Strikes the right balance between including pertinent information without being overwhelming, explaining things in a digestible way without dumbing down, etc. Inspired me to read a proper immunology primer (How the Immune System Works), which was also very good.

   * How Rights Went Wrong. An excellent, level-headed take on the U.S. conception of rights, and how it leads to zero-sum thinking in supreme court cases. The author is so relentlessly reasonable that it's hard not to buy into his argument. Even though this book is about the U.S., it has lots of case studies where it contrasts with various other countries, which helped me understand my country's (Canada's) court system and system of rights better.

   Let-downs:

   * Seeing Like a State. The first few chapters are interesting, and do a good job of explaining the world-view of the author. Worth buying just for this. However, the last half or two-thirds of the book is a tedious re-hashing of the same ideas through various examples.

   * The Precipice: Existential Risk and the Future of Humanity. Many interesting factoids in here (killer asteroids: solved problem). However, the book's central argument failed to convince me. Many of the analyses and probability estimates were disappointingly shallow and hand-wavy, especially for the #1 risk cited in the book--unaligned AI--which he thinks has a 10% chance of ending civilization this century.

   There are a LOT of anti-vaxxers who disingenuously couch their advocacy as "I'm only asking questions". It's no surprise when you've seen a 10:1 ratio of bad actors to good (or worse), one might get a little exasperated.

   In any case, I've recently been reading Lauren Sompayrac's "How the Immune System Works", and it's a technical overview of the immune system. It's not going to make you into a full blown immunologist, but it will give you the answers to most the questions you ask above, and a framework and vocabulary to begin to understand deeper academic immunology works.

   P.S. The immune system is FUCKING AWESOME. There's rarely a page where my mind is not blown.

   Edit: I misspelled "Sompayrac"; it is now correct.
