[ASD Related Information] Environmental Exposure and ASD Risk

※ Intro

- Even at this moment, researchers are actively investigating which environmental factors increase the risk of ASD. For many years, numerous theories have been raised to explain the cause of ASD. For example, parents pointed to the vaccine as the cause, saying that it rarely showed symptoms of ASD until their children were vaccinated. If ASD symptoms appeared immediately after receiving the vaccine, it would be a natural response to think that the vaccine was the cause. However, despite numerous studies, no association was revealed between vaccines and ASD. The following three theories have been raised about the relationship between vaccines and ASD.

※ three theories

1. Measles-Mumps-Rusty MMR Vaccine Damage Intestinal Membrane, Causes Autism.

2. Timerosal, a mercury-containing preservative in some vaccines, damages the nervous system, causing autism.

3. Getting vaccinated too early, or getting too many vaccines at once, affects the immune system, causing autism.
