Autism / Autism Spectrum Support Group
Autism is classified as a neurodevelopmental disorder which manifests itself in markedly abnormal social interaction, communication ability, patterns of interests, and patterns of behavior. Although the specific etiology of autism is unknown, many researchers suspect that autism results from genetically mediated vulnerabilities to environmental triggers.
About the chicken pox (Varicella) shot. Studies have shown that of the children who do get chicken pox, the future immmunity is just as strong for those who do vaccinate versus those who don't. And it rarely (chicken pox, not the vaccine), if ever, hs serious cmplications. Good Luck, hope this helps.
