Qualifications

Purpose of consultancy

The consultant shall work in coordination with the Vaccines and Immunization Devices Assessment Prequalification Team (PQT) focal points:

  • To review the safety and efficacy of specific vaccines to ensure that they fulfil the requirements as indicated in the relevant WHO and other international standards. ย 
  • To raise queries in case of incomplete data and assess the adequacy of the manufacturersโ€™ responses.
  • To make a recommendation based on the adequacy of the vaccine as per the acceptability of the WHO vaccine prequalification dossier (VPQD) in principle for purchase by UN agencies.ย 

    In order to fulfill the purpose, the consultant should:

    • Assess what published guidelines, requirements/recommendations, and international guidance documents are available from WHO and other regulatory agencies that are relevant for the evaluation of a vaccine.
    • Conduct a search for relevant publications with evidence of scientific consensus with regards to safety, immunogenicity, or clinical efficacy of a vaccine.

      All recommendations by the consultant are advisory to WHO, who retains full control over any subsequent decisions and actions, including whether to publish the findings and recommendations to accept the vaccine for acceptability in principle for purchase by UN agencies.

      Background ย 

      The World Health Organization (WHO), through its Regulation and Prequalification Department provides advice to the United Nations Childrenโ€™s Fund (UNICEF) and other United Nations agencies on the acceptability, in principle, of vaccines considered for purchase by such agencies. This service is called prequalification.

      The purpose of the WHO prequalification assessment is to provide assurance that candidate vaccines: (a) meet WHO recommendations on quality, safety and efficacy, including compliance with WHOโ€™s recommended standards for good manufacturing practices (GMP) and good clinical practice (GCP); and (b) meet the operational packaging and presentation specifications of the relevant United Nations agency. Prequalification also supports the specific needs of national immunization programmes with regards to vaccine characteristic such as potency, thermostability, presentation, labelling and shipping conditions. ย 

      The aim is to ensure that vaccines provided through the United Nations for use in national immunization services in different countries are safe, effective and suitable for the target populations at the recommended immunization schedules and with appropriate concomitant products.

      This important work is carried out with the support of international experts in Non-Clinical, Clinical and Chemistry, Manufacturing and Controls (CMC) evaluation of biological medicinal products, specifically vaccines. WHO is making a call to increase the number of consultants/experts available to support this very important public health responsibility.
