For the price it's great. Very convenient pocket size. Explains the effects of vaccines informed way. Indicates the pros and cons. Allows to avoid many incidents for you and especially your children. Personally my uncle was vaccinated against the epathite B and grabbed multiple sclerosis. The court confirm that it came from the vaccine and it was indennisé 110 000. Seen in the state where it is not gonna change much for him. An obligation to difuser information on this cursed vaccine in the media would have been better as a penalty. READ A BOOK
