Multifocal meningoencephalitis after vaccination against COVID-19 - PubMed
“The presence of SARS-CoV-2 spike protein might have been due to vaccination rather than viral infection, because no SARS-CoV-2 nucleocapsid protein was detected. The spike protein in the central nervous system might have been related to the acute ischemic change, and that in the pituitary and adrenal glands may have been associated with right heart failure, possibly through dysfunction of the renin-angiotensin-aldosterone system.”
