Hannah was described as normal, happy and precocious in her first 18 months.
Then, in July 2000, she was vaccinated against nine diseases in one doctor's visit: measles, mumps, rubella, polio, varicella, diphtheria, pertussis, tetanus, and Haemophilus influenzae.
Afterward, her health declined rapidly. She developed high fevers, stopped eating, didn't respond when spoken to, began showing signs of autism, and began having screaming fits. In 2002, Hannah's parents filed an autism claim in federal vaccine court. Five years later, the government settled the case before trial and had it sealed. It's taken more than two years for both sides to agree on how much Hannah will be compensated for her injuries.
In acknowledging Hannah's injuries, the government said vaccines aggravated an unknown mitochondrial disorder Hannah had which didn't "cause" her autism, but "resulted" in it. It's unknown how many other children have similar undiagnosed mitochondrial disorder. All other autism "test cases" have been defeated at trial. Approximately 4,800 are awaiting disposition in federal vaccine court.
