How exactly do you do a blind study without literally giving people measles? It sounds like an impossible ethical situation.

That, and the proof of the pudding is in the eating. We had about 20 years of nearly no measles cases, and didn't get them again until people stopped vaccinating.

Also, without knowing what exactly went wrong, 4 billion dollars is a meaningless number. Most malpractice suits are borderline frivolous too, so that further biases your number.

Like anything, it's about how you filter the data. If you want the absolute worst number possible, you can get that with a good data set. If you want an absolutely accurate number of people actually harmed by the vaccine and only the vaccine, you can also get that with a good data set.

It's a double blind study for vaccines vs a placebo. In vaccine studies the placebo is replaced with last year's vaccine, or another vaccine; never against a placebo.

It's always a study comparing the effects of two vaccines. There's is no placebo control.

Even cancer patients get placebos in experimental studies.
