This covers the Dr. Sears point of view pretty well:
That's right. A scary max dose of vaccine-borne aluminum is far less than that from breast milk. Check out those scores from the formulas! I'd be interested to hear from anyone here who is unable to nurse, yet still thinks aluminum from vaccines is a serious health issue. There's simply no proof.
A number is just a number. It has to be read in context.
Here's info taken from a pamphlet that was put out by the Vaccine Education Center at The Children's Hospital of Philadelphia. (the same place that Dr. Paul Offit works for that your link talks about). They pretty much skew the numbers to make them in their favor. The pamphlet was "Q&A Volume 3, Spring 2009 titled "Aluminum in Vaccines: What you should know".
Here is what they say.
|Q. How much aluminum is in vaccines?
A. During the first 6 months of life, infants could recieve about 4 milligrams of aluminum from vaccines. That's not very much: a milligram is one-thousandth of a gram and a gram is the weight of one-fifth of a teaspoon of water. During the same period, babies will also recieve about 10 milligrams of aluminum in breast milk, about 40 milligrams in infant formula, or about 120 milligrams in soy-based formula.
|Q. What happens to aluminum after it enters the body?
A. Most of the aluminum that enters the body is eliminated quickly. Though all of the aluminum present in vaccines enters the bloodstream, less then 1 percent of aluminum present in food is absorbed through the intestines into the blood. Either way, most of the aluminum in the bloodstream is immediately bound by a protein called transferrin, which carries aluminum to the kidneys where it is eliminated from the body. About 50 percent of aluminum in vaccines or in food is eliminated in less then 24 hours;85% is elminated in two weeks and 96 percent is eliminated in 3 years. The ability of the body to rapidly eliminate aluminum accounts for its excellent record of safety
Second of all they are IMO using numbers to make their beliefs look good. An infant may receive 10 mg in BM in the first 6 months of life but they are doing so over many feedings a day over a 6 month time period. That means they are getting 0.056mg of aluminum per day. To break that down even further they state that only 1 percent of the aluminum that passes through the digestive tract makes it to the bloodstream. That means that the babies kidneys only has to deal with .00056mg of aluminum.
Meanwhile, again using their numbers, an infant would receive 4 mg in the first 6 months of life from vaccines. That however is given over a course of 4 shot visits and all of it is going into the bloodstream because it isn't passing through the digestive tract. That means that a babies kidneys is now being asked to deal with 1 mg (on average to make things easier) of aluminum on 4 different days. 1 mg from vaccines is a heck of a lot different then .00056mg of aluminum from BM/day and I HIGHLY doubt that a little body that is used to handling .00056mg is capable of dealing with 1785 times more the aluminum given from a vaccine.
