First case of postmortem study in a patient vaccinated against SARS-CoV-2 – NCBI

A previously symptomless 86-year-old man received the first dose of the BNT162b2 mRNA COVID-19 vaccine. He died 4 weeks later from acute renal and respiratory failure. Although he did not present with any COVID-19-specific symptoms, he tested positive for SARS-CoV-2 before he died. Spike protein (S1) antigen-binding showed significant levels for immunoglobulin (Ig) G, while nucleocapsid IgG/IgM was not elicited. Acute bronchopneumonia and tubular failure were assigned as the cause of death at autopsy; however, we did not observe any characteristic morphological features of COVID-19. Postmortem molecular mapping by real-time polymerase chain reaction revealed relevant SARS-CoV-2 cycle threshold values in all organs examined (oropharynx, olfactory mucosa, trachea, lungs, heart, kidney and cerebrum) except for the liver and olfactory bulb. These results might suggest that the first vaccination induces immunogenicity but not sterile immunity.

Coronial autopsies identify the indirect effects of COVID-19 – The Lancet

Review of autopsy reports enabled the determination of the relative contributions of undiagnosed COVID-19 and lockdown restrictions on deaths. Of the 67 autopsies done at our hospital during the first 2 months of lockdown, only two autopsies identified COVID-19 that was undiagnosed before death. More frequently, reduced access to health-care systems associated with lockdown was identified as a probable contributory factor (six cases) or possible contributory factor (eight cases) to death. These causes included potentially preventable out-of-hospital deaths such as acute myocardial infarction and diabetic ketoacidosis, in which patients contacted the health services by telephone and were advised to self-isolate at home rather than attending hospital. Direct reference to financial or work pressures caused by COVID-19 was identified in three of ten cases of suicide.
