Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is handled in biosafety level 3 (BSL-3) facilities, whereas the antiviral screening of pseudotype virus is conducted in BSL-2 facilities. In this study, we developed a SARS-CoV-2 spike-pseudotyped virus based on a semi-replication-competent retroviral (s-RCR) vector system. The s-RCR vector system was divided into two packageable vectors, each with gag-pol and env genes. For env vector construction, SARS-CoV-2 SΔ19 env was inserted into the pCLXSN-IRES-EGFP retroviral vector t
