WHO vaccines prequalification collaborates closely with other WHO programmes (e.g. the Expanded Programme on Immunization, Polio Eradication Programme), with procurement agencies (e.g. UNICEF, PAHO Revolving Fund), and with other WHO partners (e.g. the Global Alliance for Vaccines and Immunisation (GAVI), national regulatory authorities and control laboratories, the International Coordinating Group on Vaccines Provision (ICG), vaccine manufacturers and technical specialist organizations). Together with these stakeholders, WHO works to enable WHO Member States to access quality and reliable vaccines that meet their programme needs.
Vaccines prequalification is also supported by other WHO entities, including the WHO Expert Committee on Biological Standardization that develops and adopts the standards and norms that underpin WHO vaccines prequalification, and by the WHO teams working on safety and vigilance and regulatory system strengthening.
