In the US, the rate of autism spectrum disorder is 1 in 68.
Statistics on the overall US measles infection rate are harder to find, but the highest number of infections in the past ten years was 667 in 2014. That equates to 1 in 480,000 for that year.

And since most cases of measles in the US are caused by infected immigrants, why is the alleged solution universal vaccination and NOT border controls?
