Approx. 23  hours after my son was given the DTaP, IPV, HBV, Hib1, and Pneumonia vaccines he had a seizure. It lasted 2 minutes and 49 seconds. He lost consciousness, began a pattern of tensing and relaxing his muscles repeatedly for the whole time listed above. He was then lethargic and completely nonresponsive for an hour and a half. When he regained consciousness, he cried for hours without stopping. I called the doctor to report the side effects immediately after he regained consciousness. We were referred to a doctor in the Pediatric neurology unit. We saw him a couple of times. And EEG was done and found nothing abnormal at that time. Two months later on 11/4/03, my son received another DTaP, IPV, Hib 2, and pneumonia vaccination again. This time he had the exact same reaction 16 hours after the vaccinations were administered. We were supposed to continue to see the pediatric neurologist but the doctor was relocated to a hospital out of state. There was no followup treatment provided. After those two incidents, things seemed to progress normally until my son received his MMR shot at approx 12 months of age (do not have the actual date with me right now). At that visit, he had a fever when we got home. the fever was 102.0 and I cannot recall how long that lasted. Within a week, he stopped speaking at all. I began to discuss my concerns with my pediatrician (whom I have had a good relationship with all of this time). We took the wait and see approach. By the next month, my son had stopped making eye contact at all. By the next month, he did not respond to his name. etc etc. In September of 2006 right after he turned three years old, we were able to have him evaluated by a psychologist. He was diagnosed with autism.  8/17/07 Received PCP medical records & vax records which corrected vax received 11/4/03 previously reported by parent.  VAERS database updated w/same.

Developed viral URI 6/05.   Diagnosed w/autism spectrum disorder & developmental delay by psychologist 9/06 after being referred by Child Development Services.  11/06 had bilateral otitis media & URI infection & noted to have poor speech at that time.  12/06 noted to have painful BMs & constipated, dx anal fissure.  3/07 referred to speech tx & Ped GI.  Patient also was receiving OT services FINAL DX: Autism Spectrum Disorder; cognitive & developmental defic Follow-up: Mild mental retardation, short attention span, cognitive impairment, gastrointestinal issues (severe constipation), sensory issues, lack of eye contact, speech delay, fine motor impairment, auditory processing disorder, weakened immune system, possible asthma, social impairment, dairy and wheat allergy, hypersensitivity to pain. Although I believe that thimerosal has injured my child (since prior to age 12 months, he developed normally), I believe the other preservatives (formaldehyde, aluminum bicarb. etc) have caused these symptoms as well. My son had seizures after receiving vaccines but no epilepsy was found (age 3 months and again a little later) the notes from my 1st phone call to the doctor about this are "missing" from his medical records. The "benefits" clearly do not outweigh the risks. Has proven that it is Not vaccines that prevent the spread of infectious disease - but hygiene and diet. Furthermore, vaccines are only effective for 2 weeks.
