The WHO chief wrote on Twitter that the move was a step towards vaccine equity, "prioritizing the well-being of all people everywhere at a critical time".
World Health Organization (WHO) chief Tedros Adhanom Ghebreyesus on Wednesday hailed the United States' support for a global waiver on patent protections for Covid
, describing it as a "historic decision".
The WHO chief wrote on Twitter that the move was a step towards vaccine
equity, "prioritizing the well-being of all people everywhere at a critical time".
"Now let's all move together swiftly, in solidarity, building on the ingenuity and commitment of scientists who produced life-saving Covid
," he added.
Tedros has for months pleaded for such a patent waiver -- an idea backed by India and South Africa -- arguing this would help to ramp up production and make Covid
much more accessible for poorer nations.
"If not now, when?" has become a frequent refrain from the WHO chief, who has lashed out repeatedly against perceived vaccine
-hoarding by richer nations.
Tedros clashed repeatedly with former US president Donald Trump
, who began withdrawing his country from the WHO before President Joe Biden
immediately rescinded the move upon taking office in January.
A later tweet from the WHO chief on Tuesday appeared to confirm that things had got off to a better start with Biden.
"This is a monumental moment in the fight against #COVID19," he said of US support for the patent waiver, describing Biden's commitment as "a powerful example of leadership to address global health challenges".
