Exclusive: Up to 1 million COVID vaccines expired in Nigeria last month

Up to one million COVID-19 vaccines are estimated to have expired in Nigeria last month without being used, two sources told Reuters, one of the biggest single losses of doses that shows the difficulty African nations have getting shots in arms. Governments on the continent of over one billion people have been pushing for more vaccine deliveries as inoculation rates lag richer regions, increasing the risk of new variants such as the Omicron coronavirus now spreading across South Africa. In Nigeria, Africa's most populous nation and home to more than 200 million people, fewer than 4% of adults have been fully vaccinated, according to the World Health Organization (WHO).
