Sinopharm chairman claims there has not been a single case of infection after inoculation of officials, students and workers heading overseas
Almost a million people in China have taken an emergency Covid-19 vaccine that is still in its testing phase, the company that developed the vaccine has said.
Chinese authorities released the vaccine, developed by China National Pharmaceutical Group (Sinopharm), to select groups of people in July including Chinese government officials, students, and workers travelling overseas, before the vaccines had been proven to work.
