The Democratic Republic of Congo has received 250,000 doses of the Moderna vaccine donated through the global Covax programme.
This first Moderna batch of 250,000 doses, which arrived on Monday, is part of the six million different vaccines that the central African country has been waiting for since last July.
The country had earlier in the year received a donation of the AstraZeneca vaccine.
However, since the launch of the immunisation campaign in April, less than 100,000 people have received a jab.
President Félix Tshisekedi who was also reluctant to take the jab promised to take a different one once they were available.
DR Congo is one of the countries where vaccine reluctance is high.
More than 300,000 doses of the AstraZeneca vaccines had to be disposed of when they expired last June and July.
