"The vaccine efficacy has been proven." So that the subject is taboo. We can not speak quietly with his pediatrician without it assimilates us to a cult. So we are not even informed about the risks and side effects. So that we no longer routinely asked permission to vaccinate our children. Curious by nature, especially for my children, I bought this book. I was already quite skeptical about the effectiveness of vaccines, this book has completely dispelled my doubts. I really recommend it to anyone who fear for their children. Not acting too late and it is never too late. With this book, you could talk more calmly without your beliefs that are believed you for a madman. Just make your advice, but I no longer vaccinerais my children except those which the law requires me to do.
