Mother states "He was a healthy baby smiled and cooed and after shots that day he had 103-104 fever for 3 weeks straight and encephalitis, screaming all the time and had seizures- blank stares and his developmental progress stopped, she claims to have been told by pediatrician at the time that this was a normal shot reaction" Mother states that "she called everyday to the office." I asked if he had been taken to the ER or another Physician office since he had been acting so sick. She said "no because she was told by our office to alternate Tylenol and Motrin." Mother stated he did not walk until 18 mos and did not talk until almost 3 years. She stated "He is fine now except has some dyslexia." I informed her I would send in the VAERS report on behalf of her son. Further information for Investigator. Mom prefers to be contacted by phone.
