It out there. You would ignore it anyway.
That is exactly the kind of vagueness I expect from someone who believes and posts antivax rhetoric. If "it is out there," you can certainly provide links to studies published in the scientific/medical literature, can't you?
Oh, I actually do look at some of the antivax blog links. This is because I do need to know specifically what they are saying and how they are abusing the science in order to post the actual scientific information.
