All national papers wrote that following the discovery of foreign materials in some unused vials of the Moderna COVID-19 vaccine,  the vaccination programs at a number of locations were suspended on Thursday. The substances appear to be metallic particles, and the Health Ministry assumes that their effect on human health would be negligible. No health damage has been reported by people who are believed to have received doses from the vials in question. The vials, which contain some 1.6 million doses, were distributed to 863 vaccination sites nationwide.
