Objective:

To study and analyze the development and vaccination of corona virus disease 2019 (COVID-19) vaccines in four major countries represented by China to understand the current situation of COVID-19 vaccine availability.

Methods:

The policies and plans of vaccine development in each stage were refined and summarized and then classified and counted according to the approval types and time, and descriptive statistical analysis was carried out on the relevant data from development to vaccination.

Results:

Up to March 31, 2022, the effectiveness of 13 COVID-19 vaccines developed by China, the United Kingdom, the United States and Russia were all higher than the minimum standard of the WHO (50%). China had made the largest contribution in terms of supply. In terms of vaccination volume, China had exceeded 3.27 billion doses, ranking the leading position.

Conclusion:

Vaccine purchase funds, distribution plan defects, vaccine nationalism, COVID-19 strain variation and other obstacles to effective vaccine access can be ensured and achieved by accelerating research and development, increasing production, fair distribution and expanding vaccination.
