Until now, the WHO had only approved the vaccines made by Pfizer, AstraZeneca, Johnson & Johnson and Moderna.
The approval by WHO also means that the Sinopharm vaccine can be supplied to the Covax facility, which has so far only been able to deliver 50 million doses globally.
For Trinidad and Tobago, an NDA has already been signed with China for the supply of 100,000 doses of the vaccine.
The deal, which was struck in March, was on hold pending WHO’s approval.
