Negative SARS-cov-2 antibodies, T-cell response and virus neutralisation following full vaccination in a renal transplant recipient - A call for vigilance.

This letter concerns the absence of an immunological response in a renal transplant recipient on immunosuppressive therapy after a full vaccination against SARS-CoV-2 and the need to be vigilant. We find it very important to report this to the scientific community, so that transplant patients can be monitored, protected and helped to stimulate further immunity.
