Sinovac claims media reports of vaccine having only 50% efficacy rate are misleading

It was said that a coronavirus vaccine developed by China's Sinovac has been found to be little over 50 percent effective in Brazilian clinical trials. That is significantly lower than the efficacy levels previously reported for the vaccine. It is disappointing news for Brazil, as the Chinese vaccine is one of two that the federal government has lined up to begin its immunization program. CGTN's Dong Xue speaks to the CEO of Sinovac, who says the reports are misleading.
