African Development Bank Group President Dr Akinwumi Adesina has said that the most important lesson of the Covid-19 pandemic for Africa is the need to build a defence mechanism against external shocks, especially in healthcare and financial security. Adesina, who outlined three strategic priorities for an African healthcare defence system: building quality healthcare infrastructure; developing the continent’s pharmaceutical industry; and increasing the capacity of vaccine manufacturing, said the continent needed $484 billion over the next three years to address the socio-economic impacts of the Covid-19 pandemic and support economic recovery.
