What's in a vaccine -- formaldehyde, MSG and mouse serum?

With all this talk about the hidden dangers of vaccines, especially with relation to mercury and autism, I found a recent blog entry at Rescue Post very enlightening. It showed what the ingredients -- approved by the CDC -- are in each vaccine. And, it included a link directly to the CDC's Website that shows this. Here's the direct link to the PDF file - click here. Or, here's the link to the page of files with all types of information about vaccines - click here. Another interesting file on that page is the Thimerosal content of vaccines -- click here. The ingredient list is disturbing and includes MSG, lactose (for those allergic to dairy, mouse serum formadehyde, red dye, thimerosal, yeast, calf skin, mouse brain, soy and human fetal tissue. Don't believe me -- look through the documents. (Oh, the human fetal tissue is "human diploid tissue.")
