Brief summary

In light of the current coronavirus disease 2019 (COVID-19) pandemic, the investigators want to better study the immunological characteristics of Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV2) infections in adults. The investigators invite volunteers to participate in a clinical study to better understand what happens after an infection with SARS-CoV2. By collecting and analysing blood samples of people that were infected, the investigators want to evaluate whether or not the participants had an adaptive immune response with the producting of immunoglobulin. The investigators will evaluate the quality of the antibodies and their neutralising capacity. In a selected patient group with strong antibody response, the investigators will try to reproduce them in the lab after the collection of a larger blood sample (max 72 mL) of, in case of insufficient B-cells, a leucapheresis (after consent of the patient). These antibodies can be used in clinical trials to evaluate whether the investigators can cure patients faster or prevent disease by the utilisation of these antibodies. Aside from the aforementioned information the investigators will also collect clinical data such as: demographic information, medical history, routine lab results, radiographic imaging and medication use. After the completion of the study, the samples will be stored for 30 years with consent of the participants.

Interventions

DIAGNOSTIC_TESTBlood sample

Analysing blood samples for the presence of antibody against SARS-CoV2. When impossible to collect sufficient B-cells for further typing, leucapheresis will be performed if the patient agrees.
