Research published in The National Center for Biotechnology 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 [...]
