Unfortunately there are too many examples where poor science is translated into a book that raises unfounded concerns. Are there risks with vaccines, yes, of course! However the risk of vaccine preventable disease far far far outweighs the risk of vaccine and there is credible scientific evidence to this effect. This author tries to tie other unexplained illnesses to vaccines where there is no credible scientific evidence. My advice to concerned parents is to look at the Institute of Medicine reports on risks of vaccination. These are the most comprehensive studies done on the issue, difficult reading but at least the science is sound. If you want to see reminders of what life used to be like in the US before vaccines I suggest you travel overseas and see the deaths of children daily to measles, tetanus, polio, rubella and other diseases which are easily preventable. If you had to chose between a 1 in 1000 chance of your child getting paralytic polio naturally or a 1 in 1,000,000 chance of a serious vaccine side effect, which would you chose? The author grossly overstates the risks and forgoes mention of the benefits of vaccination mankind has reaped.
