SARS-CoV-2 antibody development and immunity will be crucial for the further course of the pandemic. Until now,
it has been assumed that patients who were infected with SARS-CoV-2 develop antibodies as it is the case with other
coronaviruses, like MERS-CoV and SARS-CoV. In the present study, we analyzed the antibody development of 77
oncology patients 26 days after positive RT-qPCR testing for SARS-CoV2. RT-qPCR and anti-SARS-CoV2-antibody
methods from BGI (MGIEasy Magnetic Beads Virus DNA/RNA Extraction Kit) and Roche (Elecsys Anti-SARS-
CoV-2 immunoassay) were used, respectively, according to the manufacturers’ specifications.
Surprisingly, antibody development was detected in only 6 of 77 individuals with a confirmed history of COVID-19.
Despite of multiple testing, the remaining patients did not show measurable antibody concentrations in subsequent
