Children develop social skill between 18-24 which results in their interacting with children and adults in the community. This interaction significantly increases the risk of infectious diseases such as mumps; as such it is just before this stage that children are vaccinated to ensure they are immune before they are exposed to illness on the playground. if a child was born with a condition such as Autism which improves other brain functions but limits the desire and ability for social interactions these characteristics will not become apparent until they are placed in social situations. Since immunization serves to protect children from viruses they obtain in these situations and is administed before children become social, it would only be logical that vaccination would be administered soon before Austic characteristis are observed and the child diagnosed.

Experts have said that there are no longer any mercury or thimerosal in modern vaccines, so maybe that was true years ago, if ever there was a connection at all, but certainly there is no science to back it up.
