Has anyone else noticed doomsday’s flim-flam? S/he keeps demanding a retrospective study of vaxxed vs unvaxxed children, but keeps shifting the definitions. If a child has received even one vaxx, no matter what it is, s/he insists it can’t be included in the unvaxxed set, but if you try including it in the vaxxed set s/he’ll complain too. S/he’s never said how many shots a kid must have had to be included in the vaxxed set, but however many it is, these must be contrasted to those with no shots at all.
S/he also completely ignores the fact that the MMR vaccine is the only one suspected of causing autism, so the only logical structure for a study is those who got it v those who didn’t. Which has been done, but s/he rejects it because the unvaxxed set did get other shots, ones that are not</me> suspected, even by anti-vaxxers, of causing autism.
