European Union leaders urged U.S. President Joe Biden to lift restrictions on exports of Covid-19 vaccines to address the desperate needs of developing countries before embarking on complex discussions about whether patent waivers might also boost supply in the longer term.

European Commission approved on a new Covid vaccine contract with Pfizer Inc. and BioNTech SE, paving the way for as many as 1.8 billion doses for 2021-2023, President Ursula von der Leyen said Saturday.

European Commission President Ursula von der Leyen said she’s open to discussing President Joe Biden’s proposal to waive patents on Covid-19 vaccines, but that the U.S. needs to dramatically ramp up the number of shots it’s exporting in the short term.

Pfizer Inc.’s chief executive said that low- and middle-income countries had opted not to order the company’s Covid-19 shot, in a letter posted online after the Biden administration said it supported waiving patents to expand global access to vaccines.

Biomet Inc. lost its bid to undo a $3.55 million verdict to an Iowa woman who alleged she suffered injury from her Biomet M2a-Magnum hip prosthesis, and that the company knew of problems with the device but put revenues first, a federal court in the state held.

Michigan’s Bronson Healthcare Group Inc. was sued in federal court by two former employees who say the company mismanaged its $737 million retirement plan by failing to rein in administrative fees or swap out expensive investment options for cheaper and better-performing alternatives.
