World Health Organization Director-General Tedros Adhanom Ghebreyesus says the WHO has approved the Sinopharm Covid-19 vaccine for emergency use -- the first Chinese jab to receive the WHO's green light. The UN health agency has signed off on the two-dose vaccine, which is already being deployed in dozens of countries around the world. The WHO has already given emergency use listing to the vaccines being made by Pfizer-BioNTech, Moderna, Johnson and Johnson, and the AstraZeneca jab being produced at separate sites in India and in South Korea.
