They use a fragment of the virus's genetic material or messenger RNA to teach the body how to fight Covid-19 and build immunity.

The World Health Organisation (WHO) says African countries are running out of supplies of COVID-19 vaccines, and there is concern over the availability of further doses.

So far, seven countries have already exhausted the vaccines they received from the United Nations-backed Covax scheme.

Africa has only administered 2% of all the vaccine doses administered globally so far.
