A 71-year-old male patient was diagnosed with LGI1 encephalopathy 4 weeks following a first ChAdOx1 nCov-19 vaccination. Extensive work-up including analysis of CSF and PET examination did not reveal a tangible cause so that a vaccine-associated encephalopathy was considered as differential diagnosis. Under steroid treatment, the faciobrachial dystonic seizures subsided.

COVID-19 vaccine programmes must account for variable immune responses and waning protection. Existing descriptions of antibody responses to COVID-19 vaccination convey limited information about the mechanisms of antibody production and maintenance. We describe antibody dynamics after COVID-19 vaccination with two biologically motivated mathematical models.

Introduction: The COVID-19 pandemic accelerated new vaccine development. Limited safety data necessitated robust global safety surveillance to accurately identify and promptly communicate potential safety issues. The African Union Smart Safety Surveillance (AU-3S) program established the Joint Signal Management (JSM) group to support identification of potential vaccine safety concerns in five pilot countries (Ethiopia, Ghana, Kenya, Nigeria, South Africa), accounting for approximately 35% of the African population.

Marketing authorization holders of vaccines typically need to report brand-specific vaccine effectiveness (VE) to the regulatory authorities as part of their regulatory obligations. COVIDRIVE (now id. DRIVE) is a European public-private partnership for respiratory pathogen surveillance and studies of brand-specific VE with long-term follow-up.

The first two vaccines administered in the COVID-19 vaccination campaign of India were Covaxin (BBV152) and Covishield (ChAdOx1-nCoV-19). In this study, we evaluate the longevity and sustainability of the humoral immune response after vaccination and various factors influencing it. An observational study was conducted in individuals who received both doses of Covaxin or Covishield vaccine, and their blood samples were analyzed for total-antiRBD-SARS-CoV-2 antibodies.
