I’m currently reading On Immunity by Eula Biss, which is so good you can’t believe it. Recommended if you’re interested in vaccination, health generally, being a parent, gender, race, class, the history of medicine, Greek mythology, vampires, or if you just need an example of how to parse out a difficult subject in a warm and elegant manner.
Also, if you have money and want to make a well targeted public health intervention, I recommend buying a bunch of copies and handing them out in front of the Park Slope Food Coop and the equivalent locations in Berkeley, Ann Arbor, Laurel Canyon, Portland, and wherever else well-educated professionals aren’t getting their kids vaccinated.
