Prequalification Vector Control

WHO Prequalification Team: Vector Control Products

Vector control interventions have contributed substantially to controlling and eliminating vector-borne diseases. The 2015 World Malaria Report estimated that 663 million malaria cases had been prevented since 2001 with recent studies showing 69 per cent of cases averted were due to the use of mosquito nets, and a further ten per cent due to indoor spraying. The use of vector control products has also been critical in preventing the transmission of other major vector-borne diseases such as dengue fever, Chikungunya, Zika virus disease, Chagas disease, lymphatic filariasis, visceral leishmaniasis, and human African trypanosomiasis. If control and elimination targets for malaria and other vector-borne neglected tropical diseases are to be met over the 2020-2030 period, vector control interventions need to play an increasingly prominent role.

Effective, safe and good-quality vector control products to prevent the transmission of vector-borne diseases.


The vector control group of the WHO Prequalification Team (PQT-VC) works in close cooperation with national regulatory agencies and partner organizations, to ensure that quality vector control products are available to those who urgently need them. This is achieved through evaluation and inspection activities, and by building national capacity for the sustainable manufacture and monitoring of quality vector control products.


  • Apply uniform standards of efficacy, safety, and quality.
  • Comprehensively assess the efficacy, safety, and quality of vector control products, based on information submitted by manufacturers, and inspection of the corresponding manufacturing sites.
  • Build the capacity of staff from national regulatory authorities, quality control laboratories, and manufacturers or other private companies, to ensure the quality of vector control products.

Key output

Initially PQT-VC will assess submitted dossiers of vector control products and of manufacturing sites for pesticidal active ingredients, for inclusion in publicly available lists of prequalified products.

  • The list of prequalified vector control products will include products from the following classes which are supported by a positive public health evaluation from WHO: long lasting insecticide treated bed nets, indoor residual sprays (IRS), space sprays and larvicides.
  • The list of prequalified manufacturing sites will identify those facilities that have been and will continue to be inspected by WHO for their production of pesticidal active ingredients used to formulate end-use vector control products.

Lists of prequalified medicines, vaccines and diagnostics posted by WHO PQT were originally intended to be used by United Nations and other multilateral agencies to guide their procurement decisions. However, these lists have progressively become a vital tool for countries and/or any agency or organization involved in the bulk purchase of medical products at the country, regional or international level.
