The World Health Organisation has stated that a large number of poorer countries receiving COVID-19 vaccines through COVAX, a global vaccine sharing scheme, do not have enough doses to continue programmes, BBC News reported on Tuesday.

WHO senior adviser, Dr Bruce Aylward, said the COVAX programme had delivered 90 million doses to 131 countries.

However, he added that this was nowhere near enough to protect populations from a virus still spreading worldwide.

According to the BBC, these shortages come as some nations in Africa see a third wave of COVID-19 infections.
