Pre-submission procedure
Pre-submission form (screening)
Prospective Prequalification Holders who wish to submit a product for prequalification must begin the application process by submitting a complete pre-submission form and additional required documentation. A product manufacturer or licenced reseller should refer to the relevant IMD-PQS performance specification and verification protocol(s) to assess whether their product corresponds to an IMD-PQS product category and whether a pre-submission is warranted.
The prequalification Pre-submission form is available here.

The purpose of the pre-submission stage is to screen potential applications for prequalification to establish whether they correspond to an active IMD-PQS product category, i.e. that answers the needs of national immunization programmes. Pre-submission screening also allows IMD-PQS to identify whether a proposed product is likely to meet the programme's performance, quality and safety criteria. The information in the pre-submission form will assist WHO in determining whether the product is eligible for WHO prequalification assessment.
