Outline of the presentation • Key messages • Context • NRA strengthening • A 10-year review of progress • Constraints & challenges • Key recommendations
Key messages • The vaccine development pipeline is especially buoyant; some extremely complex products are under development; specialist regulatory oversight is needed • Paradigms are changing in the vaccine world • WHO is committed to support countries to ensure and sustain that 100% of vaccines used in all national immunization programmes are of assured quality – NRA strengthening is one strategy to attain this goal 3rd WHO Prequalification Stakeholders Meeting
Context 3rd WHO Prequalification Stakeholders Meeting
Norms and standards Development of new vaccines Regulatory processes and quality WHO vaccine portfolio: from research to disease prevention Vaccine production, supply and financing Monitoring and disease burden assessment Immunization safety Vaccine delivery and accelerated programmes 3rd WHO Prequalification Stakeholders Meeting
The Vaccine Pipeline & PQ vaccines 3rd WHO Prequalification Stakeholders Meeting
Vaccine Manufacture shift from Industrial to Developing Countries • 1992, 100% of vaccine purchased by UNICEF from Industrial Nations • 2000, 53% of vaccines purchased are from Developing Nations, which include: 25% of Polio, 90% of Measles , 85% of Yellow Fever , 79% of Hep. B. • 1997-2000, 50% of Industrial Nations left BCG, DTP and TT manufacture • 7-10 manufacturer left measles production, leaving one country supplying >90% of the UNICEF needs – risk to vaccine security. 3rd WHO Prequalification Stakeholders Meeting
Guided by Expert Committee on Standardization of Biologicals (ECBS) recommendations on safety, efficacy and quality issued in WHO Technical Report Series (TRS) World Health Organization's Goals Ensure that “100%” of vaccines used in all national immunization programmes are of assured quality • Definition of “Assured quality vaccines” • National Regulatory Authority (NRA) independent from vaccine manufacturer • NRA functional (system + 6 regulatory functions) • No unresolved problem with vaccines 3rd WHO Prequalification Stakeholders Meeting

Global production & NRA assessments100% of countries with high production volume/capacity assessed 49 countries produce vaccines 44 countries produce consistent and important volume 5 countries stopped or inconsistent/very low volume/capacity 3rd WHO Prequalification Stakeholders Meeting Source: WHO, NRA assessment, as of December 2007
Number of countries exercising all regulatory functions relevant to their source of vaccine, Dec.2007 84 Countries 65 Countries 44 Countries Number of countries
Assured quality vaccines procured through WHO prequalification scheme , 2006 14 industrialized countries 6 developing countries 24 manufacturers 65 pre-qualified vaccines used in 112 countries 53% total population 13% population
Constraints & Challenges Political commitment and support: • Some vaccine manufacturers do not believe or wish to have independent and stronger NRA oversight • Political commitment to support in country NRA activities is lacking in several countries Global supply of vaccine: • Risk of global shortage of critical vaccines in case of failure of NRA in producing countries to exercise all six functions 3rd WHO Prequalification Stakeholders Meeting
Constraints & Challenges National capacity to regulate products or contribute to WHO NRA assessments: • Lack of regulatory experts with vaccines expertise in developing countries • Opportunity costs of mentoring and training of experts for assessments because of the limited number of assessments each expert performs • Government not always keen to release national experts for WHO assessments, training and follow up visits • Difficulties to identify and train team leader for country assessment as it requires in depth and wide scope expertise • Institutional Development Plan (IDP) not always followed and often re-assessment needed to update the IDP because of obsolete recommendations or changes in structure/staff • NRAs staff lack of expertise/skills to assess new products 3rd WHO Prequalification Stakeholders Meeting
Key recommendations from 10 year review meeting NRA assessments have been key to assist countries to strengthen their regulatory system and develop plan (IDP) to meet prequalification requirements, the activities should continue by improving the following areas: • Experts: The standards of the experts, and their experience and understanding of the regulatory process, vary. Further consideration should be given to recruitment and training of experts for this work. • Improved synergies : between the WHO vaccines and medicines NRA assessment processes should be identified • Institutional Development Plan (IDP): needs to be ongoing, subject to regular (but not too frequent) review, and it needs to have built in to it sustained financial support and political will. • Decentralization: There needs to be increasing involvement of the WHO Regional Offices • Data management & analysis: data that have been generated have not been sufficiently analyzed to learn more about systems strengthening. 3rd WHO Prequalification Stakeholders Meeting
