1991 Government Document Confirms TDAP Vaccine Causes Microcephaly

Information reveals that the U.S. government knew as early as 1991 that
the Tdap vaccine causes microcephaly.
Why then are the government so keen to blame microcephaly on the recent zika virus outbreak when for at least 70 years no known cases of microcephaly had been reported as a result of the virus?
According to the study, entitled Adverse
Effects of Pertussis and Rubella Vaccines: A Report of the Committee to
Review the Adverse Consequences of Pertussis and Rubella Vaccines:
Among
symptomatic cases, presumed causes are frequently grouped according to
the timing of the suspected insult as occurring pre-, peri-, or
postnatally. Prenatal factors are thought to account for 20 to 30
percent of cases. This category includes cerebral anomalies, chromosomal
disorders, neurocutaneous syndromes such as tuberous sclerosis,
inherited metabolic disorders, intrauterine infections, family history
of seizures, and microcephaly (Bobele and Bodensteiner, 1990; Kurokawa
et al., 1980; Ohtahara, 1984; Riikonen and Donner, 1979).
Among
the earliest case reports suggesting a possible link between infantile
spasms and pertussis immunization are those of Baird and Borofsky
(1957). They described 24 children who had hypsarrhythmia and infantile
myoclonic seizures and whose development prior to the onset of spasms
was apparently normal. Nine cases of infantile spasms were reported to
have occurred between 1 and 5 days after DPT vaccination.
Three
of these nine children also had a history of perinatal complications
that the authors thought might have been related to a risk of infantile
spasms. The authors also stated, on the basis of a review of published
EEG tracings, that hypsarrhythmia was present in two of the affected
children described by Byers and Moll (1948). Since these early case
reports, additional cases of infantile spasms in association with
pertussis immunization have been described in the literature (Fukuyama
et al., 1977; Millichap, 1987; Portoian-Shuhaiber and Al Rashied, 1986).
The time intervals reported between vaccination and the onset of
infantile spasms have been from minutes to weeks (Melchior, 1971).
Evidence from Studies in Humans
One
of the largest case series of infantile spasms following pertussis
immunization was published by Millichap (1987). Six children ranging in
age from 2 to 9 months were included. The time interval from
immunization to the onset of spasms was from 6.5 hours to 5 days, and
first seizures were reported to have occurred in conjunction with the
first, second, or third doses of pertussis vaccine.
Except for one
case who had experienced myoclonic seizures since birth, no mention was
made of the children having seizures prior to immunization. In
reviewing the etiology and treatment of infantile spasms, Millichap
(1987) listed the postulated mechanisms for pertussis-related seizures
as (1) a direct neurotoxic effect, (2) an immediate immune reaction, (3)
delayed cellular hypersensitivity reaction, and (4) vaccine-induced
activation of a latent neurotropic virus infection.
