An employee of SinoVac works in a lab at a factory producing its SARS CoV-2 Vaccine for COVID-19 named CoronaVac in Beijing on Thursday, Sept. 24, 2020. SinoVac's CEO says they have injected 90 percent of its employees and family members, or about 3,000 people, and provided tens of thousands of rounds of CoronaVac to the municipal government of Beijing. It's a highly unusual move that raises ethical and safety questions, as companies and governments worldwide race to develop a vaccine that will stop the spread of the new coronavirus.
