evidence: Aluminum-containing vaccines are generally injected into the muscle, and the aluminum is released gradually into the bloodstream from the injection site over time. Taking into account the multiple possible sources of aluminum in the babies’ blood and the slow release from the vaccines, the body burden of aluminum would not be expected to rise above the safe limit, the researchers found. In fact, the level stayed at less than half the safe limit, they wrote, pointing out that this limit itself has a cushion built in and that exposure at or slightly above the limit might be safe. [...] "If the baby’s typical size, and let’s say he or she weighs about 8 pounds, the amount of aluminum in the hepatitis B vaccine alone is almost 14 times the amount of aluminum that’s FDA approved," Ty Bollinger misleadingly said in a video clip shared in a recent Instagram post. Bollinger, who owns a publishing company, has long been a prolific spreader of misinformation on topics such as cancer and vaccines. [...] Jefferson, Tom et al.
