Covid-19

Already since the start of the Covid-19 pandemic (~Feb 2020), SciCross has worked with collaborators in order to understand how the immune system responds to the virus. Focus has been on both antibody-mediated responses and the role of T-cell epitopes. SciCross designed a T-cell epitope library that has been used to evaluate T-cell responses in patients, which clearly shows how T-cells play an important role. This work was initiated by a LinkedIn post, where SciCross founder Pierre Dönnes asked for people interested in Covid-19 vaccines (doing some T-cell epitope identification on a Saturday evening 🙂

This work has led to the following publications:
