The World Health Organization (WHO) has granted emergency approval for the Covid vaccine made by Chinese firm Sinopharm, APA reports citing BBC.
It is the first vaccine developed in 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.
However, individual health regulators in various countries - especially poorer ones in Africa, Latin America and Asia - have already approved the Chinese jabs for emergency use.
With little data released internationally early on, the effectiveness of the various Chinese vaccines has long been uncertain.
Brazilian trials of another vaccine, Sinovac, for instance, showed an efficacy rate of around 50.4%, which is barely over the 50% threshold needed for approval by the WHO.
Other trials in Turkey and Indonesia have indicated a higher efficacy rate though.
