Dis. Med. Several other groups had reported a low frequency of somatic mutations in SARS-CoV-2 neutralizing antibodies101,102,103, which suggests that germline-encoded B cell receptor sequences have a sufficiently high affinity for the spike protein to limit antigen access to the germinal centre. Inevitably, we have been selective based on the common themes that we feel are the most important take-home messages from the past year; therefore, to some extent, this article represents a personal perspective of our highlights of what we have learnt so far about the immunology of COVID-19. However, there was no evidence that dexamethasone provided any benefit, and indeed may lead to possible harm, among patients who were not receiving respiratory support. JAMA 323, 20892090 (2020).
