The OP did indeed have zero evidence. I would like to see empirical, methodologically sound, replicated, peer-review studies that clearly demonstrate a causal effect between vaccines and autism (or other such negative effects that vaccines are claimed to cause), and are able to illustrate a biological explanation for such a phenomenon.
No such study has ever done this, and most (high-profile) studies that have suggested a connection have been redacted from their respective journals (including, most importantly, the study that started this nonsense in the first place). Most 'scientists' or 'doctors' that peddle anti-vaccination rhetoric or pseudo-science almost always seem to be a position of financial gain for doing so.
The burden of proof lies on people like you to demonstrate your claims with independently verifiable evidence. This is especially true if the alternative would result in death and/or suffering from preventable diseases.
Post hoc ergo propter hoc. The notion that vaccines should be "more spaced out" can be very harmful and put children at risk from catching otherwise preventable infectious diseases that they can die from. A child having many vaccinations at once or within a short space of time doesn't put strain on their immune system or have any other risks. Immunisation programs are designed to maximise the benefit to the child.
