The World Health Organization (WHO) has granted emergency approval for the Covid vaccine developed by Chinese firm Sinopharm.
It is the first vaccine made by a non-Western country to get WHO backing.
China has already vaccinated millions of people at home and in 45 other countries.
Until now, the WHO had only approved the vaccines made by Pfizer, AstraZeneca, Johnson & Johnson and Moderna.
But individual health regulators in various countries - especially poorer ones in Africa, Latin America and Asia - have already approved Chinese jabs for emergency use.
With little data released internationally early on, the effectiveness of the various Chinese vaccines has long been uncertain.
