So ...you’ve got the cause of Autism down to a single vaccine or maybe “two”! If so, you need to go on national television with this, provide that evidence to everyone - and you’ll go down in the history books as leading the way to finding the cause of Autism ... :-) ...
I haven’t mentioned autism and vaccines.
I contradicted your ‘the child hasn’t been vaccinated’ statement.
Unless someone was in the room with the child 24hrs a day just after birth you can assume the child was vaccinated against HepB. At least the first dose. Hospitals get bennies for 100% compliance with that one. I know 2 kids who got it in spite of the parents written refusal. One of the parents was an admitting doctor at that particular hospital. Let’s just say things got ‘...testy...’ after he found out his kid had gotten it in SPITE of his written refusal.
