WHO says 'vaccine nationalism' cannot beat virus
"For the world to recover faster, it has to recover together, because it's a globalised world: the economies are intertwined. Part of the world or a few countries cannot be a safe haven and recover.
"The damage from COVID-19 could be less when those countries who... have the funding commit to this.
"They are not giving charity to others: they are doing it for themselves, because when the rest of the world recovers and opens up, they also benefit."
He said the existence of the deadly respiratory disease anywhere put lives and livelihoods at risk everywhere.
Race for the vaccine
The United Nations health agency also said that multiple different types of vaccines would likely be needed to combat COVID-19.
Twenty-six candidate vaccines are in various stages of being tested on humans, with six having reached Phase 3 wider levels of testing.
"Phase 3 doesn't mean nearly there," explained the WHO's emergencies director Michael Ryan.
"We've got a good range of products across a number of different platforms, across a number of different countries," he said of the leading candidate vaccines, which use different methods to provide immunity.
However, "there's no guarantee that any of these six will give us the answer -- and we probably will need more than one vaccine to do this job."
'Americas remain epicentre'
The novel coronavirus has killed over 708,000 people and infected more than 18.8 million since the outbreak emerged in China last December, according to a tally from official sources compiled by AFP.
"The Americas remain the current epicentre of the virus and have been particularly hit hard," said Tedros, with the United States, Brazil and Mexico suffering the most deaths.
Asked about the virus raging in the Americas, Ryan said no country had always found all the right answers, and a vast expansion of the public health workforce was required.
"We need to take a step back, we need to look at the problem again and we need to go at the problem again," he said.
"That requires strong, sustained and trusted leadership."
