The World Health Organization (WHO) has criticised what it describes as a "shocking imbalance" in the distribution of coronavirus vaccines between rich and poor countries.

The group's chief said a target of seeing vaccination programmes under way in every country by Saturday would be missed.

The WHO has long called for fairer distribution of Covid-19 vaccines.

It is leading the Covax scheme which is designed to get jabs to poorer nations.

So far, more than 38 million doses have been delivered to around 100 countries under the scheme.

Covax hopes to deliver more than two billion doses to people in 190 countries in less than a year. In particular, it wants to ensure that 92 poorer countries will receive access to vaccines at the same time as wealthier countries.
