Transparency is a key principle of WHO prequalification. Public reports developed as part of the assessment and inspection processes are therefore posted to the website as they are available. Currently, the available WHO Public Assessment Reports (WHOPARs) for vector control products (VCP) can be found on the associated product page.
A WHO Public Inspection Report (WHOPIR) is posted following inspection of the manufacturing site of a VCP. WHOPIRs are posted only for those sites that have passed inspection and can be accessed via this website.
A WHOPIR remains on this website for three years, after which it is moved to the Archived WHOPIRs section.
