NRA Training Workshop - Foundational Principles for National Regulatory Authorities in the Evaluation of Vector Control Product Dossiers
Last 9-12 December 2025, the WHO Prequalification Unit – Special Prequalification Programmes group (PQT/SPP) successfully launched their pilot training “Foundational Principles for National Regulatory Authorities in the Evaluation of Vector Control Product Dossiers”. This pilot training program aimed to strengthen the technical capacity of National Regulatory Authorities (NRAs) to conduct rigorous, evidence-based evaluations of Vector Control Product (VCP) dossiers. Emphasis was placed on the quality component, including how the outcomes of the quality assessment inform the evaluation and interpretation of safety and efficacy data.
This initiative is aligned with WHO’s broader commitment to promoting reliance approaches and supporting member states in achieving regulatory self-sufficiency. It also represents a key step toward standardizing assessment practices and enhancing collaboration between countries and regulatory networks.
PQT/SPP looks forward to expanding this initiative to continue equipping NRAs with the tools and skills needed for independent, evidence-based decision-making, fostering resilience, enhancing trust in regulatory systems, and ultimately contributing to improved health outcomes in affected communities.
ePQS Portal
The ePQS Submission Portal has been supporting VCP and VCAI submissions since May 2025. In 2025, 29% of all VCP/VCAI submissions were submitted via the ePQS portal. We encourage all applicants to utilize the ePQS submission portal to streamline the screening process. Please visit the ePQS homepage to learn how to access the portal.
Until 31 March, 2026, submissions may still be received outside of the ePQS portal. After this date, the use of the portal in submitting applications to WHO PQ will be mandatory.
Prequalified products
In 2025, PQT/VCP has prequalified 9 products representing 4 different product types including the first spatial emanator products to be prequalified following the WHO conditional recommendation.
Further details can be found on the prequalification page for each product.

All products that have been accepted for PQT/VCP assessment can be found on the pipeline page.
Target timelines for assessment and listing decision(s) are 365 WHO days from the date of acceptance for assessment. WHO days are defined as those days in which the product dossier is with WHO for assessment, i.e., does not include manufacturer time to respond to Requests for Information.
Procedures for Vector Control Active Ingredients
The document "Overview of the WHO Assessment of Vector Control Active Ingredient Products" was developed to provide manufacturers and other stakeholders with an overview of the WHO assessment for VCAIs. Manufacturers wishing to apply for WHO assessment of their VCAI product(s) should read this document before applying, so that they can be aware of, and prepared for, all aspects of the VCAI assessment confirmation of compliance process.
These procedures describe the roles and responsibilities of WHO as well as the terms and conditions agreed to by manufacturers as part of their voluntary participation in the process of WHO specification development and confirmation of compliance.
Ensuring the quality of the active ingredient source materials used in prequalified VCPs is critical for ensuring the quality, safety and efficacy of end use products. These procedures address WHO’s use of the recommendations provided through the Joint Meeting on Pesticide Specifications (JMPS) to support the listing of those source material producers who have demonstrated compliance with the established WHO specifications. Furthermore, it ensures WHO can manage and maintain its decisions to list products throughout their regulatory lifecycle.
