Data Collection Event

ILEVIA - Community Elderly unvaccinated - Visit 4

Visit 4 took place 3 months after the second dose of vaccine to assess immunity durability.

Information on demographics (age), health status (known Covid-19 infection, testing, hospitalization; symptoms; chronic condition), travel history, COVID-19-related risk behaviours (mask-wearing, social distancing, public gathering, self-isolation) and COVID-19 vaccine details (date, side-effects).

Blood samples were collected for detection of the presence of soluble biomarkers of inflammation, antibodies specific for SARS-CoV-2, and antibodies specific to other human coronaviruses; and the examination of cell specimens for general features of innate and adaptive immunity as well as the presence of SARS-CoV-2-specific immunity.

Specific data (e.g. clinical frailty scores, dates of prior COVID-19 tests) were collected form medical records (if available).
