Sinovac, the mainland vaccine manufacturer, has delayed the results of its phase three trials. Brazilian researchers said on Wednesday that preliminary data suggests Sinovac jabs are "more than 50 percent effective.'' Health Secretary Sophia Chan Siu-chee had previously expected Hong Kong to get hold of the vaccine in January and have people injected by February or March. Meanwhile, University of Hong Kong microbiologist Ho Pak-leung played down concerns over Sinovac’s delay in announcing the latest clinical data. “For mainland vaccines, relevant departments like the National Medical Products Administration have tight supervision over the production and other areas,” he told an RTHK programme.
