World Health Organization boss ​​Dr Tedros Adhanom Ghebreyesus has been censored on China’s internet after he said the country’s ‘zero-COVID’ policy was “not sustainable”. Several Chinese cities including Shanghai and Beijing have been under some form of lockdown since the start of the year as Omicron cases spread. In a rare criticism of a government’s handling of the pandemic, Dr Tedros called for shift in China’s approach yesterday, citing Omicron’s increased transmissibility and the health/economic affects of China’s hard lockdowns. His comments come days after President Xi Jinping vowed to double down on the policy. New modelling by Chinese and American scientists found the country risks more than 1.5 million COVID deaths if it drops its current policy without any safeguards due to low vaccination rates among the elderly and Chinese vaccine Sinovac providing relatively lower protections against newer strains of the virus.
