Dr Tao Lina, who practices in Shanghai, has been censored after claiming that the Sinopharm vaccine authorised for use in China is “the most unsafe vaccine in the world and has 73 different side effects.” Hours after posting this on Weibo he retracted the comment and apologised to his country for his “imprudent” remarks. Dr Lina initially listed side effects including headaches, high blood pressure and urinary incontinence.
