As wealthy countries stockpiled COVID-19 vaccines, 50 percent of adults in Europe, the United States and the United Kingdom have now been fully vaccinated.

Meanwhile, vaccination rates remain extremely low in countries across Africa, where fewer than two percent of the continent's people have been fully vaccinated.

The director of the Africa Centres for Disease Control and Prevention, Dr John Nkengasong, talks to Al Jazeera.
