Conclusions and Relevance
In this large sample of privately insured children with older siblings, receipt of the MMR vaccine was not associated with increased risk of ASD, regardless of whether older siblings had ASD. These findings indicate no harmful association between MMR vaccine receipt and ASD even among children already at higher risk for ASD.

Despite research showing no link between the measles-mumps-rubella (MMR) vaccine and autism spectrum disorders (ASD), beliefs that the vaccine causes autism persist, leading to lower vaccination levels. Parents who already have a child with ASD may be especially wary of vaccinations.
• A relative risk of 1 means there is no difference in risk between the two groups.
• An RR of < 1 means the event is less likely to occur in the experimental group than in the control group.
• An RR of > 1 means the event is more likely to occur in the experimental group than in the control group
For children with older siblings with ASD, at age 2, the adjusted relative risk (RR) of ASD for 1 dose of MMR vaccine vs no vaccine was 0.76 (95% CI, 0.49-1.18; P = .22), and at age 5, the RR of ASD for 2 doses compared with no vaccine was 0.56 (95% CI, 0.31-1.01; P = .052).
For children whose older siblings did not have ASD, at age 2, the adjusted RR of ASD for 1 dose was 0.91 (95% CI, 0.67-1.20; P = .50) and at age 5, the RR of ASD for 2 doses was 1.12 (95% CI, 0.78-1.59; P = .55).

I believe the study included 96,000 children -- that's a huge study.
From my experience, anti-vax people can't be swayed from their opinion, so arguing with them is pretty much useless.
For example, they'll probably claim if there isn't a link between vaccines and autism, why all the studies? Everything gets turned around and becomes part of the conspiracy.
It all started with bad science. The now-debunked theory that autism is caused by the common immunizations nearly all children receive beginning in infancy began with a fabricated piece of research, a 1998 study published—and later retracted—in the journal Lancet. In 2010, Great Britain stripped Andrew Wakefield, the lead author of the study, of his medical license. An investigation had deemed his research an elaborate fraud. But in those dozen years, fear of lifesaving immunizations took hold of millions of parents. Jenny McCarthy—former Playmate of the year, model, actress, and soon-to-be cohost of the television show The View—fueled parental fears. She built a movement around the flawed theory. McCarthy, who has an autistic son, wrote Louder Than Words: A Mother's Journey in Healing Autism, correlating the increase in childhood vaccinations with the rise in autism worldwide. "She is absolutely entitled to her opinion, but to say that it's fact when it's not fact is just wrong," says Glenn Braunstein, vice president of clinical innovation at Cedars-Sinai Medical Center in Los Angeles. "It's one step down from yelling 'fire' in a crowded theater when there is no fire. It's fear-mongering."
this one covers the IBS aspect as well as the alleged autism connection
A leading virologist is calling on the scientific community to spend no more time investigating alleged links between the MMR (measles, mumps, and rubella) vaccine, inflammatory bowel disease, and autism after the publication last week of two further studies, which seemed to demolish the theory that vaccination increased the risk of the conditions. The studies—one published in the Lancet by a team from the Royal Free Hospital Medical School, London, the second in Current Problems in Pharmacovigilance from a specially convened working party of the Committee on Safety of Medicines—both found no evidence that the vaccine causes either autism or inflammatory bowel disease, which has been suggested as the link mechanism. In the Royal Free’s study, Brent Taylor, professor of community child health, and colleagues investigated 498 children with autism born since 1979 in the North Thames region. They found that the age at which autism was diagnosed was the same regardless of whether they had received the MMR vaccine before or after 18 months old or had never been vaccinated. There was no clustering of developmental regression after vaccination, and no more children in the group with autism had been immunised than in the general population of the region. The team said that, although the number of cases of autism had increased steadily since 1979, there was no sign of any steep rise coinciding with the introduction of the MMR vaccine in 1988. The Committee on the Safety of Medicines’ study examined medical records of 92 children with autism and 15 with Crohn’s disease; the records had been passed to the committee by a firm of solicitors. Evidence of autism before vaccination was found in 36 cases, and another 28 showed family history of the condition. Eight autistic children and four with Crohn’s disease seemed to have developed symptoms after MMR vaccination, but, the authors said, the small numbers and the fact that onset of autism frequently occurs around age 18 months meant that this is not enough to prove causation. Add these findings to those of last year’s Medical Research Council’s team of 37 experts who examined the issue and also concluded that no link existed, and, said Norman Begg, head of the Communicable Disease Surveillance Centre’s immunisation division, it is clear this issue must now be laid to rest. “These are important papers. They are further evidence that this vaccine causes neither autism nor inflammatory bowel disease,” he stated.
and Re ginger taylor from your link (86 studies confriming a link to austisim) is hammered quite thoroughly by the author over at skepical raptor for what its worth to you
However, it’s more than these vaccine deniers just cherry-pick bad studies. They ignore the vast weight of evidence of real science published in real journals. Not only do we lack evidence that vaccines cause autism, we have affirmative evidence that vaccines do not cause autism. Here’s a list 110 peer-reviewed articles, published in high impact factor journals, that document the lack of correlation (and therefore causation) between vaccines and autism.
Ginger is pandering to her uneducated acolytes who don’t actually know how to read scientific articles. Lucky for humanity and the health of children who won’t have to suffer from vaccine preventable diseases, some of us know how to read and refute Ginger’s list of bogus studies. What’s particularly laughable is that she uses numerous citations from Lucija Tomljenovic and Christopher Shaw, both of whom could be generously described as real shills for the antivaccination movement. Very well paid shills in fact. There articles are based on ludicrous science, published in terrible open access, and some cases, cursory peer-reviewed journals. If these two antivaccine shills actually had real data, why isn’t it published in top notch journals that relish the publicity of cutting-edge science. Like Lancet. Or New England Journal of Medicine. I guess if you have bogus data published in bad journals, you get what you get. Right Ginger Taylor?
Abstract BACKGROUND: A causal relationship between the measles, mumps, and rubella (MMR) vaccine and occurrence of autism spectrum disorders (ASD) has been claimed, based on an increase in ASD in the USA and the UK after introduction of the MMR vaccine. However, the possibility that this increase is coincidental has not been eliminated. The unique circumstances of a Japanese MMR vaccination program provide an opportunity for comparison of ASD incidence before and after termination of the program. METHODS: This study examined cumulative incidence of ASD up to age seven for children born from 1988 to 1996 in Kohoku Ward (population approximately 300,000), Yokohama, Japan. ASD cases included all cases of pervasive developmental disorders according to ICD-10 guidelines. RESULTS: The MMR vaccination rate in the city of Yokohama declined significantly in the birth cohorts of years 1988 through 1992, and not a single vaccination was administered in 1993 or thereafter. In contrast, cumulative incidence of ASD up to age seven increased significantly in the birth cohorts of years 1988 through 1996 and most notably rose dramatically beginning with the birth cohort of 1993. CONCLUSIONS: The significance of this finding is that MMR vaccination is most unlikely to be a main cause of ASD, that it cannot explain the rise over time in the incidence of ASD, and that withdrawal of MMR in countries where it is still being used cannot be expected to lead to a reduction in the incidence of ASD.
