Develop and make available to researchers globally a repository of coronaviruses (as available), pseudoviruses (if they can be made), and antigens. The repository could be developed in a tiered fashion, with an initial focus on the highest-risk viruses and then adding additional viruses over time.
The BEI Resource Repository has SARS-CoV-2 isolates and antigens available to researchers, with corresponding product sheets and Certificates of Analysis; non-SARS-CoV-2 coronaviruses are available as well.
ATCC has a repository of various human and animal coronavirus isolates available.
Antigens from human and animal coronaviruses are also available commercially. CDCreativeDiagnostics, SinoBiological, R&D Systems, and others have coronavirus-specific repositories
