Bioinformatics analysis suggests that most people would be capable of readily producing neutralizing antibodies against SARS-CoV-2 in severe cases of COVID-19. Moreover, combinations of different types of neutralizing antibodies completely blocked the live virus from spreading. According to the authors, these antibody cocktails can be further tested in clinical settings as a useful means to prevent and treat COVID-19.
