Please use the following statements to write this paper. I know there is a lot of jumping around, but I need it all included!
what are some of the possible causes of autism, can vaccines be to blame?
what is autism and what are the symptoms and diagnosis?
-some beliefs of causes and any link with genetics
main focus: look at different cases and research to see what kind of links are there
is there any research to identify genetics that make some children suceptible to adverse vaccine reactions?
if any of these adverse reactions are identified, is it possible to screen children for genetic markers before receiving a vaccie?
what are some ways to help children with autism?
please use some quotes from the book Evidence of Harmby David Kirby and some internet sites.
Thank you!!!!!!!!!!
