THE HEMOPHILIA COMMUNITY AND WYETH: A HISTORY OF PARTNERSHIP

Support of Children’s Camping Initiatives

For years, Wyeth has recognized the importance of the summer camp experience to children in the bleeding disorders community. Since 1998, Wyeth has been a major sponsor of Barretstown in Ireland – an innovative recreational facility – where children with serious illnesses, including children with hemophilia, can participate in a range of fun activities that also are designed to promote self-confidence, independence, trust and coping skills. In addition to its ongoing support, Wyeth works with Barretstown to help run special camps for children with hemophilia.

Wyeth is also the founding and exclusive sponsor of NACCHO (North American Camping Conference of Hemophilia Organizations). The annual NACCHO conference is dedicated to the sharing of best practices for bleeding disorder summer camps. Through NACCHO, children attending summer camp also have the opportunity to participate in Leading Edge: Exploring the Outer Limits, a nationally run adventure program that focuses on self-confidence development for youth and adolescents in the bleeding disorders community. Through its grants to NACCHO, Wyeth has supported 1,000 campers nationally, and 500 campers internationally.

Wyeth-Sponsored Support Programs

Education and access to care are critical to the health and well-being of patients with hemophilia. In addition to other initiatives that support the bleeding disorders community, Wyeth proudly awards scholarships to deserving students who have hemophilia. For the 2008-2009 academic year alone, Wyeth awarded up to $100,000 to students with bleeding disorders seeking collegiate, graduate and vocational degrees. Wyeth also works to help patients with hemophilia maintain access to hemophilia therapy. Through its Factor Resource Program, Wyeth provides services designed to assist patients experiencing financial hardship or treatment access issues, including the Insurance-Coverage Program and the Patient Assistance Program. Individuals can get more information about these programs through the Wyeth Hemophilia Hotline (1-888-999-2349).

* National Hemophilia Foundation’s Campaign for Our Future, a program designed to provide access to care for all members of the bleeding disorders community.
* Hemophilia Federation of America’s Helping Hands program, which provides emergency financial assistance for members of the bleeding disorders community. Last year, Wyeth supported 122 families through its grants to the Hemophilia Federation of America.
