Q. Should vaccines be "greener"?
If vaccines contain ingredients like aluminum or formaldehyde, wouldn't it be better if vaccine makers got rid of these additives? We agree that this sounds reasonable -- but it doesn't mean that current vaccines are unsafe. Here's the key point: additives like aluminum in vaccines are in extremely small amounts (often, just a trace). We are all exposed to significantly higher levels of environmental toxins in our everyday activities.
Let's look at aluminum. Babies ingest 50 micrograms of aluminum per liter of breast milk . . . and 500 micrograms of aluminum per liter of formula. By contrast, the amount of aluminum in a vaccine is much smaller. Do you wear antiperspirant? That's got aluminum in it too. And aluminum is found in most food, soil and water. So, to avoid aluminum exposure, you'd have to stop wearing antiperspirant-and basically leave the planet. And aluminum poisoning does not cause symptoms of autism, either.20 Trace amounts (far less than what your baby eats everyday) of aluminum improve the body's immune response to some vaccines. That's why it is in there.
Why is formaldehyde in vaccines? Well, small amounts sterilize the vaccine fluid so your child doesn't get something like the flesh-eating Strep bacteria when he gets his shots. If you use paper towels or mascara, or have carpeting in your home, you've been exposed to formaldehyde. Obviously, exposure to large amounts of formaldehyde is not a good thing for anyone's health. But, again the amount in vaccines is extremely small.22 The bottom line: vaccine additives are there for a reason-to make them safer and more effective.
