CHCC will review only autism cases that meet the following criteria: (1) an MMR was received; (2) the child then regressed; (3) the child has gastrointestinal symptoms; (4) measles virus has been recovered in the blood, gut tissue, or cerebral spinal fluid; and (5) the symptoms after the MMR occurred within the past three years. Please be asssured we will continue to provide instructions (and forms) to persons who wish to file by themselves. However, those persons who still wish to file should be aware that: (1) the deadline to file a claim in the Vaccine Program is, at the latest, three (3) years from the date of the diagnosis and possibly as early as three (3) years from the onset of symptoms; (2) the presence of thimerosal (ethylmercury) in the Hep B, HiB, and/or DTaP vaccines is essential to our theory that these vaccines caused symptoms on the spectrum; (3) manufacturers of these vaccines claim to have stopped using thimerosal in the production of new vaccines beginning in the year 2000; and (4) there is a $250 filing fee required by the United States Court of Federal Claims.
