My husband received the Anthrax shot shortly after 9-11, right before his ship deployed to the middle east.
I will tell you that he had issues with an irregular heartbeat almost immediately after receiving the shot and continued to have problems with his heart for nearly 5 years afterwards.
As for Autism in children related to the vaccine... We have a 12 year old son who was diagnosed with Autism. We had him before my husband was vaccinated. Neither of our younger two children have autism. I do not believe there is a link between the vaccination itself and autism in children. There is, however; a link for it being inherited. After receiving my son's diagnosis we found that there were several members of my dad's side of the family whose children were also diagnosed within the autism spectrum.
If you feel that the person who received the shot has suffered damage because of it, please, have a physician check into it. I do know people who have received benefits based on the shots causing health issues.
As for the Autism diagnosis and feeling the need to place blame, I know where you are coming from. We played the blame game for a while. Then we just accepted it and chose to battle the disability. There are things you can do to make the symptoms better and to teach your child how to interact socially. Your efforts will be better spent looking for a positive future than they will in trying to find blame somewhere in the past.
I hope this helps. :)
