Have you ever read the book SOME CALL IT AIDS, I CALL IT MURDER?
This book by Eva Snead, MD is all about the reasons not to vaccinate, and there are many.
It is not just the additives. Virus material injected into the body is extremely harmful in many ways. A virus strand is a protein and cannot live or die. It can be damaged, but can be revived and become virulent again.
Many if not most vaccinations have "ride along" viral material. These extras include helper virus material, retro viruses, etc.
We all want to believe there is a a cure, or prevention for diseases. vaccinations are an aluring, even seductive idea. Take a shot and no worries. It is a trap many fall victim to.
