WHO approves Sinovac Biotech’s coronavirus vaccine for emergency use

A Covid-19 vaccine by China’s Sinovac Biotech was approved for emergency use by the World Health Organization (WHO) on June 1, 2021. It is the second vaccine from a Chinese drug maker to receive the listing in less than a month. The move has the potential to help the dose-strapped Covax vaccine distribution programme. The WHO has already approved vaccines from Sinopharm, Pfizer/BioNTech, Moderna, Johnson & Johnson, AstraZeneca and the Serum Institute of India.
