The COVID-19 pandemic has devastated human health and global economy.Diminished immune function of health-related vulnerable populations leads to insufficient protective effect of the vaccine with a higher risk of severe illness and death following infection,and there is a lack of adequate targeted drugs for the prevention and treatment of COVID-19.In the context that COVID-19 treated as a Category B disease in China,vulnerable populations have become the priority populations for epidemic prevention and control.Therefore,the strategies of individual immunization and prevention should be further optimized for vulnerable populations.In addition to vaccines,other prevention strategies should be supplemented,such as long-acting neutralizing antibodies.Based on this,this paper reviews the identification,immune function characteristics and prevention strategies of COVID-19 in vulnerable populations,to provide a reference for the prevention and control strategies for health-related vulnerable populations in China,expecting that more suitable preventive drugs for vulnerable populations can be developed in the future to reduce the risk of COVID-19 in vulnerable populations.
