Winter in the southern hemisphere could also be worsening the numbers given that more people are indoors, allowing the virus to spread more easily.
African countries have got 80% of Covid-19 vaccines acquired to date into people’s arms, but only 1% of the population is fully vaccinated.

“The key, a plea, is for continuous support to the continent. We are very desperate to scale up vaccines and have used 80% of the vaccines acquired.”
