PQS Devices Catalogue 2020


The PQS on-line catalog includes details of all immunization-related products currently pre-qualified by WHO for procurement by United Nations agencies. The catalog is produced and maintained by the Quality, Safety, and Standards group in the Immunization, Vaccine and Biologicals Department of WHO, Geneva.

The WHO Performance, Quality and Safety (PQS) process prequalifies products and devices so that member states and UN purchasing agencies are assured of their suitability for use in immunization programs. The PQS process also encourages a wide range of manufacturers to apply for prequalification so that a competitive marketplace develops.
