John Nkengasong, the director of the Africa Centres for Disease Control and Prevention, says that the continent will, going forward, only accept donated COVID-19 vaccines with a shelf life of at least three to six months, to enable beneficiary countries to have enough time to plan and execute a rollout before they expire. This, he said, as 2.8 million doses of vaccine had expired on the continent, roughly 0.5% of the accumulated 572 million doses donated so far. AfricaNews reports that Nkengasong explained that the expired doses are usually among those donated by individual countries or via the global vaccine-sharing scheme COVAX, which arrive with “very short notice”. In contrast, doses of the Johnson and Johnson vaccine acquired by African countries via a scheme organised by the 55-member African Union and delivered with a longer shelf life had not expired, he said.
