In re Merck Mumps Vaccine Antitrust Litigation, 13-cv-03555 (E.D. Pa.)
Robins Kaplan serves as court-appointed co-lead counsel on behalf of a proposed class of direct purchasers of the mumps vaccine from Merck. Plaintiffs allege that Merck unlawfully monopolized the U.S. market for the mumps vaccine by engaging in a decade-long scheme to exclude competing manufacturers through false and misleading claims on its product labels. Merck annually derives hundreds of millions of dollars of revenue from its mumps vaccine. Litigation remains ongoing.
