Some doctors tell you to vaccinate, that it is safe and will protect your child.
Other doctors tell you it is not safe, and that it can harm your child.
Remember that the doctors that tell you that it is safe have vested interests, such as their careers and pharma kick-backs.
The doctors/scientists that expose the truth about vaccines have everything to lose including their careers, their recognition in the the medical establishment etc. Do you suppose they would expose the truth if it were not true? Would they risk everything, if their knowledge were not substantial?
Be fair to yourself and your children and educate yourself. Read the books, visit websites. Do what you must to educate yourself on the issue.
