The Democratic Republic of Congo has received 250,000 doses of the Moderna vaccine donated through the global Covax programme.
It is the first time the country has received a vaccine other than the AstraZeneca jab.
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.
Since the launch of the immunisation campaign against Covid-19 on 19 April, less than 100,000 people have received a jab.
DR Congo is one of the countries where vaccine reluctance is high.
