Summary on WNV and Blood Safety
  • Identification of risk for WNV in the blood safety
  • Initiative of OBRR/CBER call for test development
  • Collaboration between the various sectors: Government, Academia, Industry and Blood establishments

  • Nationwide implementation of blood screening for WNV under FDA expedite approved INDs
28
Lessons Learned
  • Challenges to industry can be met
  • Interactive cooperation between government, academia, professional organization (AABB task force), device manufacturers and users is feasible and can generate appropriate response to public health crises
  • Information generated in Blood Establishment may have public health value for community intervention

36
FIVE LAYERS OF BLOOD SAFETY
  • FDA’s approach is to optimize each safety layer:
  • Donor screening and deferral based on geographic, behavioral and medical risk factors (donor education, self deferral, donor interview)
  • Laboratory testing and deferral (HIV-1, HIV-2, HBV, HCV, HTLV-I, HTLV-II, WNV, syphilis)
  • Deferral registries to prevent use of blood from deferred donors
  • Quarantine controls to prevent unit release pending verification of donor suitability
  • Investigation and correction of deviations

Approaches to Protect the Blood Supply from Transfusion Transmitted Malaria
  • Workshop to be held on July 12, 2006
  •  Discuss the scientific issues for future policy development
43
Current Considerations
  • There is no licensed blood screening test to detect malaria infection in donor blood


  •  TTM is prevented by donor deferral policies


  •  Incidents of TTM is all time low


  •  The biggest down side of donor based prevention is the loss of approximately 150, 000 blood donors


  •  Is a blood screening test needed to further reduce the risk of TTM and minimize the donor loss?
