There is no vaccine or specific drug for the new coronavirus, but research and development has been initiated, and the virus has been successfully isolated and is being screened for seed strains. This has laid a solid foundation for vaccine development, screening of antiviral drugs, and development of rapid detection reagents. But urgency and optimism cannot change the basic rules of science, and vaccine development still needs to go through animal experiments and human clinical trials. There is still a long way to go before the vaccine is really commercialized and put into clinical application.
