>Why? Excluding religion, there is no reason to believe that vaccines cause any harm: literally every study attempting to find otherwise has either failed or been proven fraudulent.
Uh, no. You're grossly misrepresenting the case.
"Any harm" - really? All vaccines (heck, all medicine in general) carry a risk of adverse effects. There are common and minor adverse effects, and rare and serious adverse effects, including febrile seizures, allergy to the eggs used in the formulation, and so forth. What the scientific consensus is is that *vaccines are still worth it despite the risks*. That's why we don't give vaccines any more for viruses no longer in the wild - the benefit is no longer worth the risk.
From the CDC (http://www.cdc.gov/mmwr/preview/mmwrhtml/00046738.htm), adverse effects include:
1) HepB Pain at the injection site (3%-29%)
2) HepB Fever over 100*F (1%-6%)
3) HepB Anaphylaxis (1 in 600,000)
4) MMR Fever over 103*F (5%-15%)
5) MMR Rashes (5%)
6) MMR Joint Pain (3%)
7) MMR Febrile seizures, which caused the vaccine to be reformulate to reduce risk
8) MMR Aseptic meningitis, which led to the vaccine to switch strains in some countries
And so forth. All of these are based on studies, contrary to what you claimed that have found harm in vaccines.
I think you read a headline once that said, "No link between autism and vaccines" and falsely extrapolated that to mean "no reason to believe vaccines cause any harm".
