I wanted to touch on the literature for aluminum exposure as it's commonly brought up and I personally wanted to refresh my own knowledge. For those worried about "heavy metal exposure" here is some data.
Aluminum is ubiquitous in the environment, with exposure occurring primarily through food and drinking water. The European Food Safety Authority (EFSA) established a tolerable weekly intake (TWI) of 1 mg/kg body weight/week, while the Joint FAO/WHO Expert Committee on Food Additives set a provisional tolerable weekly intake (PTWI) of 2 mg/kg body weight/week.For vaccines, the FDA limits aluminum content to 0.85 mg/dose, with currently licensed vaccines containing 0.125-0.85 mg/dose. So let's for instance base this on a 10kg child. Say the child gets 4 vaccines ( injections) with max aluminum per the FDA. That ends up being 3.4mg. If we base that on the European guidelines we are 6.6mg away from the weekly recommended dose. 🤷♂️
Aluminum is cleared primarily by the kidneys, with efficient renal excretion in individuals with normal kidney function. Pharmacokinetic studies demonstrate that aluminum from intramuscular vaccines is slowly absorbed from the injection site and efficiently eliminated through glomerular filtration.After a single vaccine dose, aluminum contributes minimally to systemic levels and is rapidly cleared
Environmental aluminum exposure is extensive. Aluminum is the third most abundant element in Earth's crust and is released naturally through volcanic activity and rock weathering.Humans encounter aluminum through multiple routes: food (the primary source), drinking water, antacids, buffered analgesics, cosmetics, cookware, and occupational exposures. Recent data show that airborne aluminum represents an underestimated exposure source, with high concentrations found in lung and hilar lymph node tissues, suggesting inhalation of urban fine dust particles contributes significantly to total body burden. So us as humans are exposed significantly to aluminum as it is. One could infer that our environmental exposure greatly exceeds any vaccine exposure in our lifetime.
Average weekly aluminum exposure from food alone can reach approximately 50% of the TWI in adults, with infants and young children potentially exceeding the TWI when relying on specialized diets. When accounting for all sources (food, cosmetics, pharmaceuticals, and food contact materials), the TWI can be significantly exceeded, particularly in adolescents.
I understand people worry about ingredients in food, vaccines and what we intake every single day. It's okay to question things. It's okay to have conversation. Again we all can learn from each other. This above isn't some made up personal opinion about aluminum. It's science with references to back it up.
Hope you all learned something. I can touch on another ingredient another day. Appreciate the commentary and appreciate those wanting to learn.
