Germany on Thursday rejected a U.S. proposal to waive patent protection for coronavirus vaccines, saying the greatest constraints on production were not intellectual property but increasing capacity and ensuring quality. <br /> <br />President Joe Biden on Wednesday voiced support for a waiver in a sharp reversal of the U.S. position, and his top trade negotiator, Katherine Tai, swiftly backed negotiations at the World Trade Organization. <br /> <br />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.
