Japan suspended the use of 1.63 million doses of Moderna Inc's Covid-19 vaccine on Thursday, more than a week after the domestic distributor received reports of contaminants in some vials.<br /><br />Japan and Moderna said no safety or efficacy issues had been identified and the suspension was just a precaution. But the move prompted several Japanese companies to cancel worker vaccinations planned for Thursday and led to the European drugs regulator to launch an investigation into the matter.<br /><br />"Moderna confirms having been notified of cases of particulate matter being seen in drug product vials of its Covid-19 vaccine," the U.S. vaccine maker said in a statement, adding it put the lot in question and two adjacent lots on hold.<br /><br />-Reuters -
