在武汉发生的由新型冠状病毒SARS-CoV-2引发的人类冠状病毒病COVID-19，仅仅2个多月时间在我国及国际上70多个国家出现迅速传播，致病和死亡率高，人类生命受到了极大威胁。一些科学家火速投入研究，对SARS-CoV-2的来源和进化、形态特征和基因结构、感染和致病分子机制开展深入研究，取得了重大进展，为科学防控COVID-19提供了重要依据。根据上述研究的基础，文中对COVID-19病毒疫苗、抗体和抑制剂研发提出了设想，在研究防控COVID-19核心技术上具有一定的参考价值。

The human coronavirus disease COVID-19, caused by the new coronavirus SARS-CoV-2 in Wuhan, China, spread rapidly in China and more than 70 countries globally in just  over 2 months. Due to its high morbidity and mortality rate, human beings are under great threat. Some scientists have promptly conducted indepth researches on the source and evolution of SARS-CoV-2, morphological characteristics and gene structure, molecular mechanisms of infection and pathogenicity. Significant progress has been made, providing an important basis for scientific prevention and control of COVID-19. According to the current research progress, the article puts forward the ideas for the development of COVID19 virus vaccines, antibodies and inhibitors, which has certain reference value for the study of the core technology in COVID19 prevention and control.
