Dozens of Nigerian officials, wearing yellow high-visibility jackets and face masks, met the flight delivering the vaccines on the airport tarmac in Abuja.
The government aims to start by vaccinating front-line health-care workers, the highest-priority recipients, in Abuja on March 5, followed by strategic leaders on March 8.
Boss Mustapha, chairman of the presidential task force on Covid-19, said the government expected to receive 84 million doses of the Oxford/AstraZeneca vaccine from Covax this year, enough to inoculate 20% of the population.
Covax, led by the vaccine alliance Gavi, and the World Health Organisation, with Unicef as an implementing partner, aims to deliver nearly 2 billion doses around the world by the end of 2021.
