Different symptoms of mercury poisoning can include: irritability, depression, anxiety, visual problems, speech problems, and sensory nerve problems. When it all comes down to it, mercury is and can be very harmful. “Methylmercury accumulates in human tissue and, at certain levels, can impair cognitive development in young children.” (Vaccines and autism: Separating fact from fiction) The mercury that was used in vaccines doesn’t accumulate in the body. The mercury found in contaminated fish and water is called methylmercury, and can build up in the body and cause severe nerve damage if ingested. Methylmercury is not the same as methyl mercury. The human body eliminates ethyl mercury faster than methylmercury, which means that ethyl mercury doesn’t accumulate in human tissue. U.S. public health officials had come to the realization that the mercury that was given to children in the vaccines exceeded the limit considered safe by government standards. It is said that babies might have been exposed to a cumulative dose of 187.5 micrograms from all sources during the first six months of their life. To this day, childhood vaccines contain no more than trace amounts of thimerosal. By the age of six months old, they are exposed to a cumulative dose of less than 3 mcg of mercury from vaccines.
