Encephalitis
ANTIRABIES ANTIBODY RESPONSE IN MAN TO VACCINE MADE FROM INFECTED SUCKLING-MOUSE BRAINS.
“Antirabies vaccines produced from infected brains of adult mammals have always had the potentiality of causing post-vaccinal paralysis or allergic encephalitis in man. Attempts in recent years either to remove the paralytic factor from brain-tissue vaccines or to use as the virus source infected tissue other than nervous tissue (e.g., chick embryos) have usually resulted in a substantial reduction of the specific antirabies potency.”

Deep sequencing reveals persistence of cell-associated mumps vaccine virus in chronic encephalitis.
“Notwithstanding this, we describe here devastating neurological complications associated with the detection of live-attenuated mumps virus Jeryl Lynn (MuV(JL5)) in the brain of a child who had undergone successful allogeneic transplantation for severe combined immunodeficiency (SCID). This is the first confirmed report of MuV(JL5) associated with chronic encephalitis and highlights the need to exclude immunodeficient individuals from immunisation with live-attenuated vaccines.”

Encephalitis related to a H1N1 vaccination: case report and review of the literature.
“RESULTS: We report a case of a 26-year-old female who developed symptoms of acute encephalitis 5 days after vaccination against the pandemic 2009 A/H1N1 influenza. MRI of the brain showed confluent T2-hyperintense signal intensity changes in the deep white matter which further confirmed the diagnosis of encephalitis/acute disseminated encephalomyelitis. Despite therapy with immunoglobulins and corticosteroids, her persistent vegetative state continued. In light of the dramatic cause of this case, we reviewed all 21 other previously reported cases of central nervous system demyelination related to H1N1 vaccination and/or infection.
CONCLUSIONS: The available data suggest that even severe central nervous system demyelination i.e. acute encephalitis/disseminated encephalomyelitis and transverse myelitis may very rarely be associated with vaccination against novel influenza A/H1N1 or with A/H1N1 infection itself.”

[Recurrent encephalitis following annual influenza vaccine. Case report].
“Influenza vaccine is rarely associated with neurological adverse effects such as Guillain Barré syndrome, encephalitis or aseptic meningitis. We report the case of a male patient that presented two episodes of acute encephalitis in consecutive years, 16 and 20 days after his annual influenza vaccine shot, respectively. In both instances, patient required ICU admission and evolved with fast recovery and no sequels. The first episode was managed empirically as herpetic encephalitis but an extensive study was performed in the second episode without identifying any microorganism. Neuroimaging studies also discarded acute disseminated encephalomyelitis. Mild pleocytosis of mononuclear predominance was detected in both cases in CSF. Naranjo score punctuated 8 points indicating a probable causal relationship. Acute encephalitis is a rare adverse effect of influenza vaccine and occurs several days after immunization. It has a broad differential diagnosis, and appears to be of self-limited duration and associated with good prognosis.”

“Regarding breastfeeding, the risk was recently confirmed by a report describing vaccine-induced encephalitis occurring in an infant 8 days after primary vaccination of the mother.”

Vaccine-associated contact paralytic poliomyelitis with atypical neurological presentation.
“Paralytic poliomyelitis presenting with quadriparesis, transient encephalitis and bulbar symptoms in 2 patients in close contact with recently vaccinated children with trivalent live oral polio vaccine is described. Symmetrical lower motor neuron involvement of deltoid muscles with electromyographic confirmation was found. Upper motor neuron signs, with symmetrical hyperactive deep tendon reflexes developed in the lower extremities. Poliovirus Type-2 vaccine-like strain was cultured from one patient and both patients showed significant antibody titers rises to poliovirus. Attention is drawn to the possible clinical differences between vaccine associated poliomelitis and the usual features found in wild strain poliomyelitis. It is suggested that in selected cases, non-immunized contacts be given inactivated polio-vaccine when the vaccinees are immunized with the live oral-vaccine.”

Vaccinia virus in postvaccinal encephalitis.
“Results of virological examination of 239 samples taken from 84 children with neurological complications after smallpox vaccination are described. In postvaccinal encephalitis, vaccinia virus was isolated from blood, cerebrospinal fluid and pharyngeal secretions of 23 out of 40 children (57.5%) as well as from autopsy specimens sampled between 10-35 days after vaccination. During the acute period of disease, virus was detected in 17 out of 31 (54.2%) cerebrospinal fluid specimens. In 3 postvaccinal encephalitis cases the virus was present in brain and in a case of encephalomyelitis-in the spinal cord. These results confirmed the participation of vaccinia virus in the pathogenesis of postvaccinal encephalitis. The pathogenicity of vaccinia virus may be manifested only under a changed reactivity of the vaccinated host.”
