Blantyre, Malawi (AP) — Malawi has burned nearly 20,000 expired AstraZeneca vaccines, amid conflicting advice over what to do with the doses. Health Minister Khumbize Kandodo Chiponda put some of the vials of the expired doses into an incinerator to lead the destruction Wednesday at Kamuzu Central Hospital in Lilongwe, the capital. She said destroying the vaccines will build public confidence that all vaccines used in Malawi are good. The burned vaccines were the remainder of 102,000 doses that arrived in Malawi on March 26 with just 18 days until they expired on April 13. She said that all other doses of the shipment, donated by the African Union, were successfully administered, she said.
