From Health Impact News:
Christina England has done an excellent job of digging up some previous studies conducted in New Zealand and Germany comparing vaccinated children with unvaccinated children.
In addition to these two studies, there was also a clinical study conducted in Hong Kong in in 2012 comparing vaccinated with unvaccinated children in regards to the flu vaccine. Researchers conducted a double-blind placebo-controlled trial on children with the trivalent inactivated influenza vaccine. Their results were published in the journal Clinical Infectious Diseases in 2012, and they found that the seasonal trivalent flu vaccine resulted in 5.5 times more incidents of respiratory illness than the placebo group. Read more about the study here.
If you watch the video below of Congressman Posey questioning the CDC at an autism Congressional hearing back in November of 2012, you will hear the CDC admit that they have never conducted a study in the U.S. comparing vaccinated with unvaccinated children.
