Official data show that more than 1.2 billion people on the Chinese mainland have been fully vaccinated as of Dec 28, accounting for more than 85.6 percent of China's population. The country is steadily approaching herd immunity against SARS-CoV-2 amid Western doubts over its dynamic zero-COVID strategy. It has quickly contained outbreaks of COVID-19 in several cities during the past year which has repeatedly proved the effectiveness and correctness to applying a double insurance policy of mass vaccination under the dynamic zero-COVID.
