Sinopharm is one of the Chinese developers creating vaccines
State-owned Sinopharm is one of at least four Chinese developers working on a vaccine for the disease that has killed 1.8 million people. Beijing Biological Products, the company's unit, said on its website that the vaccine is awaiting approval following the third and final stage of testing. However, the two-sentence announcement gave no information about side effects, conditions required to transport, or other details.

The second vaccine from a Sinopharm unit
The Sinopharm vaccine relies on two doses, the company said, similar to Western-developed vaccines. It would be the second vaccine from a Sinopharm unit, following a separate candidate developed by the company's Wuhan Institute of Biological Products Ltd. Chinese producers have at least six possible vaccines in the final stage of clinical trials.

Health experts express concern about poorer countries
Even as western companies have started distributing their vaccines, some health experts have expressed concern too little will be available to poorer countries. China's government says it will ensure Chinese-developed vaccines are affordable for developing countries. Meanwhile, health experts say the certification process for the United States, Europe, Japan, and other developed countries might be too complex for Chinese vaccines to be used there.
