A study of vaccinated and unvaccinated residents of Bangladesh observed that ChAdOx1 could not prevent the new infection or severe COVID-19 disease outcome with single dose when infections were mostly caused by B.1.351 (the Beta) variants of SARS-CoV2.
About 39% (n = 42) of the respondents were infected after the COVID-19 vaccination. The first dose of ChAdOx1 nCoV-19 vaccine was received by 40 (37.0%) cases and both doses were completed by only 2 (2%) cases. The average duration between vaccination (partially or completely immunized) and COVID 19 diagnosis was 32 (±17) days.
The hospitalization rate of comorbid patients was 23.5% among the immunized and 24.1% among the nonimmunized groups. There was no significant difference in duration of hospitalization either (p=0.78).

A 21-year-old non-smoking Caucasian male with a history of acute pancreatitis but no other medical issues or family history had two doses of the BNT162b2 mRNA COVID-19 vaccine. Four months after the second dose he had his first episode of COVID-19. Although not hypoxic, he felt pretty unwell for a week, with a severe cough, fever, generalized body ache, headache, and loss of taste. He received the third dose of the vaccine two months after recovering from COVID. Nine months after the third dose, he had the second episode of COVID-19, during which he was mildly unwell for three days, recovered, and did not require any anti-viral medication or antibiotics. One week post the second episode of COVID-19, he developed diarrhea and abdominal pain. It then progressed to bloody diarrhea. Ulcerative colitis was diagnosed based on his clinical symptoms, biopsy changes, and the exclusion of other causes. There are ten published case reports about the newly diagnosed ulcerative colitis ...
A previously hypertensive 56-year-old male presented with the subacute onset of severe constipation, urinary retention, erectile dysfunction, sudomotor failure, sicca symptoms, non-reactive pupils and severe orthostatic hypotension shortly after receiving the second dose of the Comirnaty mRNA vaccine against COVID19. Autonomic testing revealed severe cardiovagal, adrenergic and sudomotor impairment, and tonic 'half-mast' pupils with evidence of sympathetic and parasympathetic denervation (see Figure). T ilt-table testing demonstrated a drop in blood pressure from 140/90 mmHg supine to 54/35 mmHg after two minutes at 60 degrees, with no heart rate response. There was no heart rate response to Valsalva maneuver and sympathetic skin responses in the hands and feet were absent. Sweat testing demonstrated complete anhidrosis. Pathological α3-ganglionic ACHR antibodies were positive in serum as detected by a new flow cytometric immunomodulation assay. Malignancy wa...
A previously healthy woman in her 60s had mild fever and uneventful course after the 1st dose of ChAdOx1 nCoV-19 vaccine, but developed behavioral problems and refusal to take food, one day after receiving the second dose of ChAdOx1 nCoV-19 vaccination (dose interval 84 days). Her condition progressed rapidly with onset of confusion, forgetfulness, and hallucinations within the next 5 days. Over the next two days, the patient developed difficulty in walking and echolalia. She was prescribed amantadine, trihexyphenidyl and clonazepam by a local practitioner but she showed further deterioration in the form of irritability, incoherent speech, aggravated forgetfulness, auditory and visual hallucinations, abnormal movements of limbs, and jaw and neck dystonia. The patient had a serum anti-Spike protein IgG titer of 1891.5 AU/mL (non-reactive<50 AU/mL) at 37 days post-second dose. An initial magnetic resonance imaging (MRI) of the brain had revealed FLAIR hyperintensity in bila...
