Antibody responses to SARS-CoV-2 in patients with novel coronavirus disease 2019. Blanco-Melo et al.29 compared transcriptional responses to SARS-CoV-2 using cell lines, ferrets and samples from patients and found that, compared with other respiratory viruses, the host immune response to SARS-CoV-2 fails to launch a robust type I and type III interferon response while simultaneously inducing high levels of chemokines and pro-inflammatory cytokines. In particular, the role of key innate viral sensors and antiviral cytokines (type I and type III interferons) in controlling virus replication and disease was unknown. Masterman, E., & Rogers, Y. Surveillance of bat coronaviruses in Kenya identifies relatives of human coronaviruses NL63 and 229E and their recombination history. As we begin to control the pandemic with a mass vaccination effort, we must also begin to close the gap created by the pandemic by supporting young and vulnerable scientists throughout the world.

This suggests that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is not the first coronavirus to cause a pandemic and, given the frequency of outbreaks (SARS-CoV in 2003 and MERS CoV since 2012), it is likely not the last one. JAMA 324, 294296 (2020). Kohmer, N., Westhaus, S., Rhl, C., Ciesek, S. & Rabenau, H. F. Brief clinical evaluation of six high-throughput SARS-CoV-2 IgG antibody assays.

Zhang et al.126 found that 23 of 659 (3.5%) patients with severe COVID-19 had deleterious mutations in 8 loci that render them incapable of producing or responding to type I interferon. Patient-derived micro-organospheres enable clinical precision oncology Infect. Thus, despite the number of neutralizing epitopes, the fact that affinity-matured antibody clonotypes have been shown to be able to cope with variant viruses141 and that it is likely that only low antibody titres are needed for protection from disease142,143,144, some viral variants of concern are potentially rendering the vaccine candidates less effective in controlling infection and disease. (2002). On 15 January 2021, the RECOVERY trial in the UK closed recruitment of patients hospitalized with COVID-19 for convalescent plasma therapy based on preliminary data from 1,873 reported deaths among 10,406 randomized patients, which showed that convalescent plasma therapy showed no significant difference in terms of the primary end point of 28-day mortality121. These studies were used by some media outlets in support of the message that many humans already have immunity to SARS-CoV-2and, by extension, that herd immunity exists and protects against COVID-19. By ro. Furthermore, another study of pre-pandemic sera from children and adults in Pennsylvania, USA, found that 23% of these individuals had non-neutralizing antibodies that cross-reacted with SARS-CoV-2 spike and nucleocapsid proteins. Here, we take readers through the timeline of key discoveries during the first year of the pandemic, which showcases the extraordinary leaps in our understanding of theimmune response to SARS-CoV-2 and highlights gaps in our knowledge as well as areas for future investigations.
