Covax: How will Covid vaccines be shared around the world?
BBC
Vaccines are being administered across the world to try and stop the coronavirus pandemic.
An international effort, known as the Covax scheme, was set up last year to try to ensure fair access to vaccines among rich and poor nations but the global situation remains vastly uneven.
More than 49 million vaccine doses have been delivered through Covax so far.
But a further $35bn-$45bn (£25bn-£32bn) is needed over the course of next year to ensure most adults are immunised, according to the Director-General of the World Health Organization (WHO) Tedros Adhanom Ghebreyesus.
