Nobody has debunked anything regarding a link between vaccines and autism.

All we saw with Wakefield is Utilitarianism, which made it necessary for the medical community to silence Wakefield. Vaccines are a greater good, regardless of the damaging affects they have on some. We use that same Utilitarian approach throughout our society and history, the wars we wage, the laws we create, in medicine, in our very education. 

"mercury" and "adjuvants" which are used in most vaccines are not safe, and have never been proven safe. Vaccines provide a greater good and as such must be protected since the good outweighs the harm caused (Utilitarianism).
