Ghana is one of the 54 countries who have failed to meet the WHO deadline.
According to a report by the BBC, the development is largely because Covax, the mechanism set up to distribute vaccine doses to poor nations, has not been able to get enough doses.
Some of the countries who have achieved the highest vaccination rates are Seychelles, Mauritius and Morocco (all above 40%).
The WHO also attributes this to their robust vaccination programs, size of the country and their population.
Others whoâve met the global target are Tunisia, Eswatini, Cape Verde, Botswana, Comoros, Zimbabwe, Equatorial Guinea, South Africa, Mauritania, Lesotho and Rwanda.
But overall, just 4% of Africans have been fully jabbed, compared with 60% in the European Union.
Covax had planned to deliver nearly 300m doses to Africa.
But itâs only been able to procure 72m doses after the richer nations bought up much of the stock.
