Dear Editor,
The pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) highlights the need to develop effective and safe vaccines. Similar to SARS-CoV, SARS-CoV-2 recognizes angiotensin-converting enzyme 2 (ACE2) as receptor for host cell entry.1,2 SARS-CoV-2 spike (S) protein consists of S1, including receptor-binding domain (RBD), and S2 subunits.3,4 We previously demonstrated that RBDs of SARS-CoV and MERS-CoV serve as important targets for the development of effective vaccines.
