Is there a replication deficient or single cycle SARS-CoV-2 available for vaccine?

01 January 1970 1 2K Report

thanks Ijaz Durrani

, the paper is based on VSV vector, not the SARS-CoV-2 itself. I mean to make a replication-deficient or single cycle SARS-CoV-2 by SARS-CoV-2 reverse genetic system.
