The global health agency said data submitted to its experts showed that two doses of the Sinovac vaccine prevented people from getting symptoms of COVID-19 in about half of those who were administered the jab. However, WHO said there were few older adults enrolled in the research, so it could not estimate how effective the vaccine was in people over 60.
Sinovac’s vaccine, branded as ‘CoronaVac’, is already being used in China and to a limited extent in Azerbaijan, Brazil, Thailand, Indonesia and Turkey, among others.
