AstraZeneca restarts another coronavirus vaccine trial, but US delay lingers

AstraZeneca and the University of Oxford have restarted an early-stage test of their experimental coronavirus vaccine in Japan following discussions with the country's drug regulator.
The trial was one of several across the globe that was halted earlier this month after a participant in a U.K. study contracted an unexplained neurological illness, triggering a safety review. AstraZeneca has since been cleared to resume testing in the U.K., Brazil, South Africa and India.
