China begins emergency use of Covid-19 vaccine despite safety concerns

Hundreds of thousands of people in China have been given a coronavirus vaccine despite the fact it has not been finally approved by regulators. The move has prompted concerns among onlookers that China is pushing ahead to gain an edge in the race to develop a successful vaccine without following proper safety measures. Chinese companies Sinopharm and SinoVac have given vaccine shots to more than 350,000 people in recent months and that number is likely set to rise.
