Autism awareness is key when you are learning to maintain a person with autism. There is much discussion about the vaccinations used for those with Autism. The vaccinations have substances that are troublesome to many. The substance is known as Mercury, also known as neurotoxin, a substance that the United States Public Health Service and the American Academy of Pediatrics recommended back in 1999. It was supposed to be removed from the vaccinations as soon as possible. Several years later this dangerous substance was being exposed to children and fetuses nationwide, causing extensive health issues. The use of Mercury is generally contained in such vaccinations as the flu shot. Practicing the use of the flu shots into pregnant women and children under the ages of three with Mercury within the vaccination injections should not be enforced and can pose to be dangerous.
