Beijing says it has inoculated more than 73,000 people in the first two days after China's first domestic coronavirus vaccine was approved for commercial use.

China's capital has set up 220 vaccination centers around the city to dole out the two-step vaccine. The elderly and front-line medical workers will receive the first doses.

The shots are made by a subsidiary of Chinese state vaccine maker Sinopharm, which said on Thursday that its vaccine is 79% effective overall. The company has not yet released more detailed clinical data that might explain why that rate is lower than results from human trials it conducted in the UAE, where the vaccine was deemed 86% effective.

However, Chinese state regulators cleared the vaccine for broader public use in China on the same day. The UAE was the first to approve Sinopharm's vaccine for commercial use in early December. Bahrain quickly followed, and a handful of countries have already placed orders for Sinopharm's vaccines, including Pakistan and Ukraine.

Since the summer, Sinopharm and another vaccine maker, Sinovac, have already injected millions of Chinese citizens, many of them state employees, under emergency use guidelines.
