AstraZeneca has resumed the U.S. trial of its experimental COVID-19 vaccine after approval by regulators, and Johnson & Johnson is preparing to resume its trial on Monday or Tuesday, the companies said on Friday.
AstraZeneca, one of the leading vaccine developers, paused its U.S. trial on Sept. 6 after a report of a serious neurological illness, believed to be transverse myelitis, in a participant in the company’s UK trial. J&J paused its large, late-stage trial last week after a study participant became ill.
