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 start the destruction Wednesday at Kamuzu Central Hospital in Lilongwe, the capital.

"We are destroying (these vaccines) because as government policy no expired health commodities are to be used," she said. "Historically under the expanded immunization program of Malawi no expired vaccine has ever been used."

She said burning the vaccines will build public confidence that all vaccines used in Malawi are good.

"We are destroying publicly in order to stay accountable to Malawians. The vaccines that expired are not being used during the vaccination campaign," she said. "On behalf of the government, I assure all Malawians that no one will be given an expired COVID vaccine."

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. All other doses of the shipment, donated by the African Union, were successfully administered, she said.

The health minister thanked WHO, the African Union and India for donating the vaccines.

"This has made it possible for Malawi to embark on the COVID vaccination campaign currently underway," she said.

Last month the World Health Organization urged African nations not to destroy expired doses of the AstraZeneca vaccine after several countries received doses from India with a very short shelf life. But this week, WHO reversed its position and said that the vaccines should be destroyed.

"Any vaccine that has passed its expiry date ... should not be administered," said WHO in a statement dated May 17. "While discarding vaccines is deeply regrettable in the context of any immunization program, WHO recommends that these expired doses should be removed from the distribution chain and safely disposed."

WHO said that in March, the African Union's African Vaccine Acquisition Task Team redistributed 925,000 doses of the AstraZeneca vaccine produced by the Serum Institute of India with an expiry date of April 13 to 13 African countries. "The bulk of these vaccine doses were administered, but some countries have unused doses remaining," said the WHO statement.

Malawi, a small southern African country of about 20 million people, had already decided to destroy its expired vaccine doses, ministry of health spokesman Joshua Malango told The Associated Press.

"We had stopped observation of proper storage mechanisms and the vaccines would have still been damaged in one way or the other," he said.

The destruction of the vaccines was witnessed by several top officials "in order to enhance transparency," health secretary Charles Mwansambo said.

Malawi will still have adequate stocks of Covid-19 vaccines in both public and private health facilities, he said. The government has not said where it will get more vaccines.

Malawi's got its first consignment of 360,000 AstraZeneca doses in early March from the U.N.-backed COVAX initiative which is providing vaccines to low- and middle-income countries. The country received another batch of 50,000 AstraZeneca doses from the Indian government. With the AU donation, Malawi had a total of 512,000 AstraZeneca doses.

So far 212,615 doses have been given in Malawi. The country has 34,216 confirmed cases, including 1,153 deaths, according to the Africa CDC.

Currently, the country is seeing a decrease in the disease, with the 7-day rolling average of daily new cases in Malawi dropping from 0.07 new cases per 100,000 people on May 4 to 0.04 new cases per 100,000 people on May 18. Official deaths from Covid-19 are also declining, according to statistics from Johns Hopkins University.

Malawi, like many other African countries, has relied on the AstraZeneca vaccine that has been distributed by COVAX and the African Union. But now supplies of the vaccine have become more scarce because India, the main supplier of vaccines to COVAX, has stopped exports until it has adequately vaccinated large numbers of its population of 1.4 billion people.

The Serum Institute of India says it hopes to start delivering coronavirus vaccines to COVAX and to other countries by the end of the year. The delay will significantly set back global efforts to immunize people against Covid-19. India's Serum Institute is the world's biggest vaccine-maker. The company said in March that it was postponing all exports of coronavirus vaccines to deal with the explosive surge of cases on the subcontinent. At the time, the World Health Organization said it expected Covid-19 vaccine deliveries from India to resume by June and the interruption would affect about 90 million doses.
