Yeah sure. Like a legitimate control group of children who weren't vaccinated couldn't be found.
A US study using patient histories would not endanger anyone.
Yes, well I am sure there are some studies, however, the US health care system is so segregated by different providers, I wouldn't be surprised if this has led to issues in doing such studies.
Unlike this one, which has been published in one of the most prestigious US medical journals, which is what you are requesting, but done in Denmark.

A Population-Based Study of Measles, Mumps, and Rubella Vaccination and Autism
METHODS
We conducted a retrospective cohort study of all children born in Denmark from January 1991 through December 1998. The cohort was selected on the basis of data from the Danish Civil Registration System, which assigns a unique identification number to every live-born infant and new resident in Denmark....................
RESULTS
Of the 537,303 children in the cohort (representing 2,129,864 person-years), 440,655 (82.0 percent) had received the MMR vaccine. We identified 316 children with a diagnosis of autistic disorder and 422 with a diagnosis of other autistic-spectrum disorders. After adjustment for potential confounders, the relative risk of autistic disorder in the group of vaccinated children, as compared with the unvaccinated group, was 0.92 (95 percent confidence interval, 0.68 to 1.24), and the relative risk of another autistic-spectrum disorder was 0.83 (95 percent confidence interval, 0.65 to 1.07). There was no association between the age at the time of vaccination, the time since vaccination, or the date of vaccination and the development of autistic disorder.
