More than half a billion doses inoculated

China’s vaccination campaign against Covid-19 has noticeably picked up speed. According to the National Health Commission, the mark of 500 million vaccine doses administered was exceeded at the beginning of the week. Health services are now administering more than 20 million doses per day nationwide, according to the report. Two doses are needed of the vaccines approved in China. The common inactivated vaccines often only have a significant effect after the second dose.
