This is a book about vaccines and their side effects more accessible than many written by Michel Georget. It helps to have an idea of the various practiced vaccines, mandatory or not, their side effects, and risks (or absence of risk) not to vaccinate their children. I think all parents should read this kind of work in order to decide in full knowledge of what is best for the health of her children. The bravest will read the book of Michel Georget, biologist "vaccinations, adverse truths" less accessible because very detailed biological and cellular level.
