Abstract
While anticipating the development of a COVID-19-specific vaccine, several randomized controlled trials (RCTs) explored the potential of BCG vaccination to protect against COVID-19, based on trials demonstrating beneficial effects of BCG vaccination on unrelated infections and all-cause mortality in neonates in high-mortality geographical settings. Results are now available from 12 RCTs, which suggest that BCG vaccination is not an effective intervention against COVID-19. That the BCG–COVID-19 trials failed to meet expectation emphasizes the importance of rigorous clinical trials to validate hypotheses, even in urgent situations such as a pandemic.
期刊介绍：
Nature Reviews Immunology is a journal that provides comprehensive coverage of all areas of immunology, including fundamental mechanisms and applied aspects. It has two international standard serial numbers (ISSN): 1474-1733 for print and 1474-1741 for online. In addition to review articles, the journal also features recent developments and new primary papers in the field, as well as reflections on influential people, papers, and events in the development of immunology. The subjects covered by Nature Reviews Immunology include allergy and asthma, autoimmunity, antigen processing and presentation, apoptosis and cell death, chemokines and chemokine receptors, cytokines and cytokine receptors, development and function of cells of the immune system, haematopoiesis, infection and immunity, immunotherapy, innate immunity, mucosal immunology and the microbiota, regulation of the immune response, signalling in the immune system, transplantation, tumour immunology and immunotherapy, and vaccine development.
