Lawyers representing AstraZeneca, Bristol-Myers Squibb, and Johnson & Johnson have requested a U.S. appeals court to reinstate lawsuits concerning Medicare drug pricing negotiations. In a separate legal development, a U.S. federal judge has denied AstraZeneca's motion to dismiss a case involving a Utah woman, Brianne Dressen, who claims to have suffered injuries from the COVID-19 vaccine during clinical trials. This decision was made by Chief Judge Robert J. Shelby of the U.S. District Court for Utah on November 4, 2024. The ruling is considered significant in the ongoing discussions around vaccine-related injuries and corporate liability.
