China okays first homegrown vaccine for coronavirus
Sinopharm says preliminary data from last-stage trials had shown the vaccine to be 79.3% effective. Experts say data such as the size of the control group and how many were vaccinated is missing.

The two-dose vaccine from state-owned Sinopharm is the first approved in China. The go-ahead comes shortly after the country launched a program to vaccinate 50 million people before the Lunar New Year holiday in February.
It also comes one day after British regulators authorized AstraZeneca's inexpensive and easy-to-handle vaccine.
