The World Health Organization (WHO) has approved China's Sinovac Covid vaccine for emergency use.
The WHO said it prevented symptomatic disease in 51% of those vaccinated and prevented severe symptoms and hospitalisation in 100% of samples.
Some evidence and data gaps are still lacking though, according to WHO experts.
It is the second Chinese vaccine to receive the green light from the WHO, after Sinopharm.
The approval opens the door for the jab to be used in the Covax programme, which aims to ensure fair access to vaccines.
The vaccine, which has already been used in several countries, has been recommended for over 18s, with a second dose two to four weeks later.
