A World Health Organization official says a total of 450,000 Covid vaccine doses have been destroyed in nine African countries.
The WHO Africa's immunisation programme manager, Dr Richard Mihigo, says a delayed shipment of the AstraZeneca vaccines, which is widely used in the continent, is to blame for this.
The countries that destroyed vaccines are Malawi, South Sudan, Liberia, Mauritania, Gambia, Sierra Leone, Guinea, Comoros, and the Democratic Republic of Congo.
Malawi was the first country to publicly destroy vaccine doses on 19 May.
The health minister says that it needed to be done to show public trust adding that to avoid wastage, countries are being urged to use up vaccines immediately after they are delivered.
