Well seems obvious to me. Pumping life into someone like that, clearly would cause damage. Maybe if the vaccine/autism link is firmly established, the super-old JW's will jump up from their wheelchairs and yell "BOOYAH!" we knew we was right that vaccination was evil befer these derned youngsters got their "new light".
In all fairness, Jehovah's Witnesses have been excellent guinea pigs and have indeed contributed to science by being so. Now, we need "new light" which reveals that the key to salvation is volunteering for dangerous medical experiments and then we'll see the full measure of Jehovah's gift to medicine.
