Re: Vaccines and Autism.
Even at safe limits it accumulates in tissue.
Accumulation of a heavy metal - a known neurotoxin - in a neonate - gives you no reason to pause?
That's why the CDC recommendations for parenteral aluminium cite "chronic feeding" as the cause for concern, not acute administration.
First parenteral nutrition is not "feeding". It is IV administration of nutrition. That is the difference between ingestion and injection.
1. There are NO studies on the elimination rates of aluminum in newborns.
2. The dosing given on day 1 of life is 0.25 - 0.5 mg of aluminum
***or to put it another way***
A 5 pound infant weighs 5 / 2.2 = 2.27 KG. x 5mcg = 11.36 mcg/d max dose. Hep B vaccine from Merck 0.5mg of Al. or 500/11.36 = a 44 day supply in a single dose on the first day of life.
How many days do you consider chronic, and what drug/compound do you know of that is SAFER to give an entire month's supply on a single day instead over an extended period of time? And if it's not going to get eliminated from the body, it IS going to accumulate.

Is there a reason you cut this out of your OP?
1. It is odd that you are debating the missing bolded areas and have total disregard to the " accumulate aluminum at levels associated with central nervous system and bone toxicity".
2. To avoid confusion. Most think that means ingestion, and do not understand the math involved as I outlined above. The above explains the "chronic" portion. A 1 day old infant does not have optimal kidney function and is probably at a greater risk of getting neuro toxicity by receiving over a months supply of Al in a single bolus. Or do you disagree?
3. The impaired renal function of a newborn is well documented and the part left out was to avoid confusion because the left in part was the needed bit of information.
To stop any confusion such as what you brought up... read the above. New borns do not have fully funcional kidneys.
Why would I offer my child to do something unnecessary?
1. If it's unnecessary then why are you supporting the administration of the vaccine? AND why do you seem concerned if there is nothing to be concerned with?
2. Two Hep B vaccines currently exist. Merck 0.5 mg Al content. Baxter (I think) 0.25 mg Al content. Each are given on the first day of life to EVERY new born even premies WITH IMPAIRED KIDNEY FUNCTION. have people volunteer to have the larger Al dosed vaccine and track the 2 groups to autism.
Again which vaccine would you sign you child up for? I answered you question, will you answer mine?
EDIT: IMPARED RENAL FUNCTION FOR INFANTS...
"Several aspects of renal function varyconsiderably during the 1st year of life and differ markedly from the equivalent values in the adult. Glomerular filtration rate (GFR) increases little, prior to the time an infant reaches a conceptional age of 34 weeks, the point in renal development from which the absolute GFR (ml/min) increases gradually to mature values when linear growth is completed during adolescence. G
FR corrected for body size is not comparable with adult normal values until after 12 months of age;"
