Febrile Seizures after Childhood Vaccination and the Development of Neuropsychiatric Disorders

Combination Shots Trigger Febrile Convulsions Which Can Lead to ESSENCE Syndromes

By Peter A. McCullough, MD, MPH

I have been impressed with the emotional tension felt from parents anxious, fatigued, and overwhelmed with a child suffering from a developmental neuropsychiatric disorder. Autism spectrum disorder, the prototype, ranges from severely developmentally disabled requiring 24 x 7 care to nearly completely mainstreamed. At several large public events I asked: “how many of you have been touched by autism in your family or social circles?” Each time it is about one third of the crowd. The most common vignette for the onset of autism is a febrile seizure, most commonly before the age of five, and after that point a clear regression in milestones, loss of eye contact, and then the classic neuropsychiatric manifestations of autism emerge over the remainder of childhood.

I have previously reported on older combination vaccinates (DTP) and the incidence of febrile seizures. Putting multiple vaccines into one shot increases the risk. I wondered if the more modern MMR vaccines by Merck and GSK had made any progress in safer vaccine products without the risk of febrile seizures.
