Coalition for Mercury-Free Drugs v. Sebelius, 671 F.3d 1275, was a 2012 case decided by the United States Court of Appeals for the District of Columbia Circuit, holding that opponents of thimerosal-preserved vaccines lacked standing to challenge determinations by the Food and Drug Administration that the vaccines and their components were safe and effective. The named defendant in the case, Kathleen Sebelius, was the Secretary of the United States Department of Health and Human Services, the department with authority over the FDA.
