China's COVID-19 Vaccination Strategy and Its Impact on the Global Pandemic.

Public health crises are challenging for governments and health systems. Vaccines are a key solution to viruses, and immunization has always played a critical role during public health crises in the past century. In the context of coronavirus disease 2019 (COVID-19), we explore China's vaccination strategies and challenges. Accordingly, we identify the causes of the high vaccination rate in China, including technical and nontechnical factors. Considering the impact of China's high vaccination rate on the global pandemic, we argue that it has strengthened China's opportunities and capabilities to participate in global development, enhanced the equity of vaccines and given the world community more choices.

Have Elderly Individuals in Urban China Been Satisfied with Nursing Services during the COVID-19 Pandemic?

Based on the customer satisfaction index model, we constructed an elderly care service satisfaction model that includes 5 latent variables and 16 observed variables. To analyze the degree of satisfaction of elderly individuals in nursing homes, we used structural equation model (SEM) to test the nursing service elderly satisfaction model. With the help of AMOS 22.0 software, we analyzed the degree of model fit and the behavioral relationships between the variables that affect the path. We found that the satisfaction of Chinese urban elderly individuals in nursing homes is at a moderate level, which is lower than the quality expected by elderly individuals. The customer satisfaction index model can be applied to assess satisfaction with nursing services. Furthermore, perceived quality and value have a significant impact on satisfaction.
