(there is data but he isn't qualified to understand it, but looking at it it sure looks scary don't it)

Seriously there are databases on vaccine issues, and if you read them as a layperson it is freaky. You immediately start getting wary of them, this was a backfire of their original purpose though. The ironic thing is that these databases are made public on purpose so the public would feel better about vaccines, but that relies on a public that is actually, you know, diligent about data.

The databases are populated by anything that happens after getting a vaccine. That means if you get strep throat after getting a vaccine? It goes in the database. Now a doctor or trained people know what is actually attributable to vaccines and what isn't, and can filter that information and mark it as irrelevant, but to an untrained person it's Oh god look vaccines cause cancer. No they don't. The lifetime smoker at age 77 does have lung cancer, but just because she got lung cancer after receiving the vaccine does not mean that it's related.

And this is of course just ignoring the fact that OP is talking about a government conspiracy to hide data from us while also referencing public databases full of data about vaccine safety.
