As part of the development of updates to the existing guidelines and guidance for data generation to support the prequalification of indoor residual spraying (IRS) products, it was determined that a product review was necessary to identify and address any gaps in the available information for these products.  

A product review process is intended to address an issue which impacts a group of products sharing certain attributes.  The process includes:

• Identification of a need for a review of information across multiple products sharing similar characteristics or a class of products
• Identification of the relevant products based on the issue
• Review of existing information
• Identification of new information/data gaps to be addressed
• Applicant submission of information based on the identified needs
• Evaluation of submitted information to inform next steps

The product review relied upon available information from existing dossiers and responses the call for information sent to all manufacturers of prequalified products.  All prequalified products, including those converted from WHOPES recommendations where considered within the scope of the process. 

WHO has published the Product Review Report concerning IRS products in accordance with the key principles of WHO prequalification. 

In order to ensure that the confidentiality of information requested, submitted and reviewed through this process is protected, the published Product Review Report is focused on the key findings and recommendations developed by the working group.  The key findings, recommendations and complete analysis of the available information will inform the development of new Guidelines and Implementation Guidance for the development of prequalification dossiers for IRS products.
