Defeating the coronavirus pandemic will require unprecedented cooperation from the research community. This is especially true for the Adaptive Immune Receptor Repertoire Community (AIRR-C), given the paramount importance of antibodies and T cells for vaccines, diagnostics, and therapeutics in viral infection. Therefore, the AIRR-C hereby calls upon its members, and the wider research community, to share experiences, resources, samples, and data as openly and freely as possible, and to work within their respective systems to break down barriers to achieve this goal, subject to the overarching directives of respect, privacy, and protection for patients and all people. We are in this together.
