Procurement Agencies


Procurement of WHO-prequalified immunization products contributes to WHO's goal of increasing the uptake and use of appropriate, quality-assured immunization equipment and devices. WHO-prequalified products offer procurers:

  • assurance that the products procured meet international standards for quality and safety and the evolving needs of national immunization programmes
  • better value for money because evaluation of products for prequalification takes into account the various and challenging operating conditions of the environments within which the Expanded Programme for Immunization (EPI) operates as well as the need to minimize product maintenance and running costs.

The procurement of WHO-prequalified products helps safeguard the potency of vaccines used in national EPI programmes. Moreover, the introduction of newer and more expensive vaccines is more secure when supported by WHO-prequalified products.
