I found this article that is short and sweet. It pretty much tells the truth and summarizes most of what I have read in a simple way that's easy to understand. I will post the link and an excerpt.
Here is the link: http://www.sunherb.com/truth_about_vaccines.htm
Excerpt:
When one understands what exactly is in these vaccines and how they are made, one would wonder how vaccines could possibly be of any benefit to health. Vaccines are produced from either dead or live attenuated (weakened) disease microorganisms. In the dead vaccines, viruses or bacteria have been have been inactivated by heat, radiation or poisonous chemicals. However, there is no guarantee that all of the microorganisms have been killed. If just one microbe survives it can multiply very rapidly and actually create the disease. This has been known to happen. In fact, every case of polio during the 1980’s was caused by the polio vaccine.
Vaccines created from live attenuated viruses and bacteria are made from the pus of animals that have been infected with disease and then butchered. In these vaccines, the live virus must be weakened by passing the virus through animal tissue several times to reduce its potency for human use. The measles virus is passed through chick embryos, the polio virus through monkey kidneys, and the rubella virus through the dissected organs of an aborted human (yes human!) fetus. The weakened germ is then stabilized by adding drugs, antibiotics, and toxic disinfectants such as neomycin, streptomycin, aluminum hydroxide, formaldehyde, and thimerosal (a mercury derivative). Studies have shown that even microscopic dosages of some of these substances can lead to cancer, neurological damage, and death.
