Correlation doesn't necessarily mean causation. A 1% correlation between vaccination and autism, as shown in the widest ranging study on this subject, definitely doesn't indicate causation. Even if we accept that there's a 1% chance of developing autism as a direct result of vaccination, that is much more preferable to them dying of a preventable disease, or being patient zero for this century's bubonic plague. One can put pressure on organisations to more thoroughly explore whether the 1% correlation is the fault of an element of the vaccine solution. In the meantime, the sensible thing to do is prevent your child from catching deadly preventable diseases.
