Menactra (Sanofi) Antitrust Settlement

Menactra Antitrust Litigation Settlement - Castro, et al. v. Sanofi Pasteur Inc., No. 11-7178

Settlement Fund:            $61,500,000
Settlement Period:          March 1, 2010 – December 31, 2014
Claim Filing Deadline:    January 18, 2018


The Court overseeing the Menactra (Sanofi) Settlement has preliminarily approved a $61.5 million settlement. Class Members such as physicians, medical practices, and health systems who bought Menactra directly from Sanofi claim that they paid higher prices than they should have for quadrivalent meningococcal vaccines (“MCV4 Vaccines”). These vaccines inoculate against four strains of bacterial meningitis. The lawsuit alleged that the higher prices resulted from Sanofi engaging in anticompetitive conduct.


All persons or entities in the United States and its territories that purchased Menactra directly from defendant Sanofi Pasteur Inc. (“Sanofi”) or any of its divisions, subsidiaries, predecessors or affiliates, such as VaxServe, Inc., during the period from March 1, 2010 through and including December 31, 2014 (“Settlement Period”), and excluding all governmental entities, Sanofi, Sanofi’s divisions, subsidiaries, predecessors, and affiliates, Kaiser Permanente and the Kaiser Foundation (collectively “Kaiser”), and any purchases by entities buying Menactra pursuant to a publicly negotiated price (i.e., governmental purchasers).

Generally, you are included in this case as a Class Member if you:

  • Are a person or entity (such as a medical practice), in the United States and its territories; and
  • Purchased Menactra directly from Sanofi Pasteur Inc. or any of its divisions, subsidiaries, predecessors, or affiliates (such as VaxServe, Inc.) from March 1, 2010 through and including December 31, 2014.


Approval of the Settlement was granted by the Court on October 20, 2017.

The deadline for eligible Class Members to submit a claim has been set for January 18, 2018.
