President Joe Biden on Wednesday voiced support for a waiver in a sharp reversal of the US position, and his top trade negotiator, Katherine Tai, swiftly backed negotiations at the World Trade Organisation.
The German government stood behind the goal of a worldwide supply of COVID-19 vaccines, a government spokeswoman said, adding however that the main factors in vaccine production are capacity and quality standards, and not patents.
"The protection of intellectual property is a source of innovation and must remain so in the future," the spokeswoman said in a statement.
She said Germany supported the COVAX initiative, with the aim of ensuring that as many people in the world as possible have access to vaccines, adding that discussions were continuing at the WTO.
The WTO said in April that of 700 million vaccines administered around the world, only 0.2 percent had been in low-income countries. A recent surge of infections in India, the world's second most populous country, has underlined the point.
The European Union is willing to discuss a proposal to waive intellectual property rights for COVID-19 vaccines, European Commission President Ursula von der Leyen said on Thursday, as drugmakers fought their ground.
