🛑 [Complications of pertussis immunization (author transl)].
“16 cases of neurological disease and/or death shortly after pertussis immunization are reported. Eight patients had convulsions, six with ensuing permanent defects. Severe polymyositis was observed in one case. Five infants died 12 h to 4 days after vaccination: two after acute encephalopathy and three in the form of a sudden unexpected death (SID). In two fatal cases the morphological changes in the brain corresponded to those of pertussis encephalopathy: neuronal degeneration in various parts of the cortex, especially in the region of the ammons horn, and in the cerebellum. There were no signs of inflammation. Three cases underwent forensic autopsy and death was attributed to bronchopulmonary infection. Complete neuropathological work-up was only done in one case, in which the brain was normal. The critique of episodical reports and the demand for prospective studies is appreciated. Knowledge of all possible forms of complications, however, is indispensable for future investigations. Polymyositis and SID have so far not been listed as abnormal reactions to immunization. The majority of our cases became known accidentally from hospital sheets or from discussions with collegues. For a detection of all possible cases a greater awareness of doctors for the problem of pertussis immunization appears necessary. Only another 23 cases have been reported to the health authorities of the state of Lower Saxony during the last 6 to 7 years. Of those, nine were either harmless reactions or diseases probably unrelated to vaccination. Two were cases of SID, 12 and 72 h after vaccination. It is concluded that only a minor proportion of possible complications is presently reported to the health authorities.”

Japan’s experience in pertussis epidemiology and vaccination in the past thirty years.
“61 encephalopathy deaths and 18 shock deaths due to the vaccine were reported from 1952-1974, but this figure is probably low.”

[Neurologic manifestations following pertussis vaccination].
“Twenty cases of acute neurological complications occuring within 7 days of pertussis immunization are reported. Convulsions were present in every case and status epilepticus was observed in five infants. In only 4 cases were neurological or epileptic sequelae lacking. The clustering of neurological complications in the 24 hours following immunization is not consistent with the hypothesis of a mere temporal coincidence. However, the mechanism and incidence of post-immunization encephalopathies remains obscure and epidemiological studies are in order.”

Revisiting the possibility of serious adverse events from the whole cell pertussis vaccine: were metabolically vulnerable children at risk?
“In the early 1980’s concerns about the safety of the whole cell pertussis vaccine in the United States resulted in declining vaccination rates and the withdrawal of multiple vaccine providers from the market. While the possibility of inflammation and febrile reactions to the vaccine were acknowledged by public health authorities, parents also claimed the vaccine was associated with sudden infant death syndrome and encephalopathy. Epidemiological studies examining this question, however, consistently failed to identify an association. We argue that these reactions may have occurred in metabolically vulnerable children, specifically those with defects in fatty acid oxidation. In these children the combination of anorexia and fever that could be caused by the vaccine may have resulted in hypoglycemic episodes and possibly death. We believe that this association was not detected because these conditions were not recognized at the time and because these conditions are uncommon. Nevertheless, at a population level, enough events could have occurred to cause concern amongst parents.”

Simian cytomegalovirus-related stealth virus isolated from the cerebrospinal fluid of a patient with bipolar psychosis and acute encephalopathy.
“A cytopathic ‘stealth’ virus was cultured from the cerebrospinal fluid of a patient with a bipolar psychotic disorder who developed a severe encephalopathy leading to a vegetative state. DNA sequencing of a polymerase chain reaction-amplified product from infected cultures has identified the virus as an African green monkey simian cytomegalovirus (SCMV)-related stealth virus. The virus is similar to the SCMV-related stealth virus isolated from a patient with chronic fatigue syndrome. The findings support the concepts that stealth viruses can account for a spectrum of dysfunctional brain diseases and that some of these viruses may have arisen from live polio viral vaccines.”

Vaccine-related adverse events in Cuban children, 1999-2008.
“The DTwP vaccine exhibited the highest rate of adverse events. Common minor events were: fever (17,538), reactions at injection site (4470) and systemic side effects (2422). Rare events (by WHO definition) reported were: persistent crying (2666), hypotonic-hyporesponsive episodes (3), encephalopathy (2) and febrile seizures (112). Severe events included: anaphylaxis (2), respiratory distress (1), multiple organ failure (1), sudden death (1), vaccine-associated paralytic poliomyelitis (2), toxic shock syndrome (3), and sepsis (1). The 10 deaths and 3 cases of disability were investigated by an expert commission, which concluded that 8 of the 13 severe events were vaccination-related.”
