I read this for Mark Zuckerberg's book club, A Year Of Books. With all the drama with measles and whether or not to vaccinate your child this was a good read due to the times. I felt like a lot of the information was no shit Sherlock material, but then you remember how many people disagree with facts & statistics despite the research backing them. For example, side effects, the book makes it clear with data that vaccinations cannot be proven to cause autism. I liked how the book explained her immunity (if majority gets vaccinated the few who can't or their body doesn't react to the vaccination are safe because they are less likely to be exposed). I hadn't drawn that conclusion, but it makes perfect sense. I felt the book lacked details at times, it was a very shallow look into vaccinations focusing on the history and reasons why parents chose not to vaccinate and then debunking their reasoning. I get why it didn't go deep because the author was telling her findings when she was researching vaccinations for her newborn son and it is a concern parents have. The book was all over the place at times and the author's obsession with vampires was getting on my nerves. Overall a good book to introduce vaccination debate and the history, plus its a quick read with 160ish pages of content.
