You don't need to even bother with any reputable source. The simple fact is this. If you want to beat an anti-vaxxer in an argument, simply give in to them. Admit every single thing they said is true.
Now, with that said. We are going to assume that measles causes 10 autism cases per 1000 kids. A 1% rate.
Measles alone, and JUST Measles, in a first world country, has a 0.3% mortality rate - http://jid.oxfordjournals.org/content/189/Supplement_1/S4.full
Now we have 3 dead kids, against 10 autistic ones. This doesn't factor in the kids maimed and permanently blinded by complications of just measles.
Now throw in rubella, diphtheria, polio, smallpox, pertussis, hep b, influenza, mumps and chicken pox.
How are those 10 autistic kids looking against the pile of dead, blind and scarred kids.
Exactly. I can concede every single point to an anti-vaxxer and still show the outcome is better with vaccines.
