This is Lynn and her son Jeremy, who has autism—a disabling brain affliction. But at 18 months old, he had a 10-word vocabulary and was growing normally. Then, two days after he received a shot for diphtheria, whooping cough and tetanus, he was in the hospital. He was running a fever of 103 and he was so hot that the nurse that was standing there could feel the heat radiating off his body. For the last 29 years, Jeremy has not spoken an intelligible word. Cases like this are not uncommon. Forty-five hundred families are suing the government because they believe vaccines caused their children’s autism.
