> they do not take into consideration that other things also cause autism

Fortunately, we have figured out how to tease out the influence of a single variable among many: test vs. control groups. If the sample size is large enough, most variables will average out to have the same effect in both groups.

there has not been a single randomized large scale study on any vaccine that investigates its relationship to autism. without that, the bars are too big. and the relationship is extremely tiny. from a practical perspective, it isnt even worth going after. the studies that have been done so far prove that it wouldnt be worth it to stop vaccinations, not even close. but they dont definitively disprove a connection. they only disprove a meaningful connection.

I saw a funny facebook group that convinced me that people whose children's lives were ruined by vaccines are dumb. And not just dumb but very dumb. Because if it's SCIENCE you have to believe it. Never mind the countless examples where the science is political and motivated by money.
