The unequal distribution of COVID vaccines is the single biggest threat to ending the coronavirus pandemic, the World Health Organization (WHO) has warned.
During his opening speech at Friday's media briefing on the COVID-19 pandemic, WHO director general Dr Tedros Ghebreyesus said that of 335 million doses of vaccine that have been administered worldwide, 76% of those are in just 10 countries.
"The inequitable distribution of vaccines remains the biggest threat to ending the pandemic and driving a global recovery," he said.
Out of the 10 countries that have carried out the most vaccines per 100 people, eight are classified as 'high income' by the World Bank. Serbia and the Maldives are the only two nations not on that list.
Ghebreyesus also warned that by stockpiling materials needed to produce vaccines, countries could be putting lives at risk across the world.

"Manufacturing any vaccine requires a lot of supplies, including glass vials and plastic filters, and the raw materials needed to make them," he said.
"The sudden increase in demand for vaccine production has led to a shortage of these and other supplies, which is limiting the production of vaccines for COVID-19 and could put the supply of routine childhood vaccines at risk.
"Some countries have imposed legal restrictions on the export of critical supplies. This is putting lives at risk around the world."
Ghebreyesus called on all countries not to stockpile supplies that are needed urgently to ramp up production of vaccines.
He said: "In a global pandemic, no country can go it alone. We are all inter-dependent."

And the director general urged nations not to see vaccines as the ultimate solution to the COVID crisis.
"No country can simply vaccinate its way out of this pandemic," he added.
"We cannot end the pandemic anywhere unless we end it everywhere.
"The longer the virus circulates, the higher the chances that variants will emerge that make vaccines less effective."
By Friday more than 23 million people in the UK had received at least one dose of a coronavirus vaccine - part of the biggest inoculation programme the country has ever launched.
The government aims to offer a first vaccine dose to about 32 million people in nine priority groups by 15 April and the programme in England is now inviting those aged 56 and above to book appointments after the first four groups - those aged 70 and over, care home residents, healthcare workers and people required to shield - were offered a jab by mid-February.
Vaccines Minister Nadhim Zahawi told MPs this week that although supply had been "finite" until now, the country would see a "big uplift" in available doses in the second half of March - amounting to tens of millions of jabs.
This would mean a "rapid increase" in the number of vaccines administered, he said.
