The World Health Organization (WHO) has granted emergency approval for the Covid vaccine made by Chinese company Sinopharm.
It is the first vaccine developed by a non-Western country to get WHO backing.
The vaccine has already been given to millions of people in China and elsewhere.
The WHO had previously 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 approved Chinese jabs for emergency use.
With little data released internationally early on, the effectiveness of the various Chinese vaccines has long been uncertain.
