14 About WHO WHO is the directing and coordinating authority for health within the United Nations system. It is responsible for providing leadership on global health matters Shaping the health research agenda Setting norms and standards Articulating evidence-based policy options Providing technical support to countries Monitoring and assessing health trends.

17 WHO Vaccine Position Papers Position papers = Key reference documents Developmental and review process (follow recommendations of SAGE, extensive peer review, evidence-base, periodic updating) Format Weekly Epidemiological Record Current structure (Intro, background (Disease epidemiology, the pathogen, disease), info on vaccines (composition, safety, immune response, efficacy and effectiveness, cost effectiveness and any other relevant issue), WHO position on vaccine use) Additional posting of information on the web: Grading of Recommendations Assessment, Development and Evaluation (GRADE) tables, references, summaries (one pager and PowerPoint presentation)

18 Global coverage estimates, DTP3, Measles, HepB3, Hib3, PCV3 and Rota Source: WHO/UNICEF coverage estimates 2010 revision. July ,000 unvaccinated infants (DPT3) in EURO, % live in countries eligible for GAVI Alliance funding

19 Supported by a $37 million 4-year grant from GAVI/GVF Haemophilus influenzae type b (Hib) is a bacterium which can cause meningitis and severe pneumonia 3 million cases of serious illness and 400,000 deaths each year in children under 5 years of age from Hib In 2006, only 26% of children worldwide received Hib vaccine 1/3 of the countries eligible for funding from the GAVI Alliance (i.e., Gross national income/capita <$1000 per year) are using Hib vaccines The Hib Initiative focuses on coordination, communication and research.

21 Global Alliance for Vaccines and Immunization

22 The Global Fund For Children s Vaccines GAVI Board Establishes Principles recommendations on fund allocation Contributors Gates Foundation USA, UK, Norway, Netherlands,... $$$ The Fund Independent Board for fundraising & management Working Capital Account (at UNICEF) for vaccine procurement and resource disbursement Three Sub-accounts: Immunization services Vaccines & Safe injection materials R & D (not yet active) Financial Tools: Vaccine Shares, matching grants procurement Strengthened Immunization Services and New Vaccines Delivered in Countries

23 GAVI: Five Strategic Objectives Improve access to sustainable immunization services Expand use of all existing cost-effective vaccines Accelerate introduction of new vaccines Accelerate R&D on vaccines for developing countries, (HIV/AIDS, malaria and tuberculosis) Make immunization coverage a centrepiece in international development efforts

26 We still could reduce 1/5 of childhood deaths with current or upcoming vaccines

27 GAVI new vaccines support Vaccines currently supported Pentavalent Pneumococcal conjugate Rotavirus Measles second dose Meningococcal A conjugate (campaigns) Yellow Fever (routine & campaigns) Measles campaigns in selected countries and outbreak response Under review 2013 and later Japanese encephalitis Typhoid Dengue Malaria New in 2012: HPV (national introduction & demo project) Rubella (MR campaigns) Also: meningitis and yellow fever vaccine stockpiles

28 New Key GAVI policies Country eligibility policy: Threshold for 2012 is $1,520 GNI per capita (World Bank, Atlas method) updated annually New vaccine introduction grant and operational support for campaigns policy NEW! Co-financing policy

29 Vaccine introduction grant and operational support for campaigns policy Vaccine introduction grant levels Vaccines delivered to infants HPV vaccines GAVI support $0.80 per child in the birth cohort Or lump sum $100,000 $2.40 per girl Or lump sum $100,000 Applicable to Penta, Rota, Pneumo, M2D, Rubella routine, YF routine HPV Operational support for campaigns level GAVI support Applicable to All supported campaigns $0.65 per target person MenA campaign, YF campaign, MR campaign, measles campaigns

30 GAVI programmatic policies Co-financing Policy Objective: to enhance ownership and put countries on a trajectory towards financial sustainability to prepare for phasing out of GAVI support. All countries applying for NVS are required to co-finance a portion of the cost of requested vaccines* 3 country groupings according to GNI per capita: Country group GNI per capita threshold Co-financing requirement Low income currently <$1,005 $0.20 per dose Intermediary currently >$1,005 to <$1,520 Graduating Currently > $1,520 $0.20 per dose + 15% annual increase Gradual ramp up over five years to reach projected price after GAVI *The only exceptions from co-financing are vaccines for measles second dose, MenA and YF preventive campaigns and MR. Countries are however expected to pay a share of operational costs of campaigns.

31 UNICEF is the world s largest purchaser of vaccines for developing countries and a key partner in global immunisation efforts. Its supply division, based in Copenhagen, is responsible for global purchasing, including some $100 million per year spent on vaccines and safe injection equipment 31

32 Estimated Global Distribution of Rotavirusrelated Deaths (from Parashar, 2006) Europe 11,838 United States and Canada 125 Latin America 18,981 Africa 229,701 Asia 289,354 32

33 Forecasted Rotavirus Demand- Doses All Regions 33 Approximately 160 million doses in peak year 2021 for 64 GAVI-eligible countries

37 Social Problems for the 21 st Century Safety and Acceptance Cost and Availability Sufficient Production 37

38 Global Immunization Vision and Strategy (GIVS) for the period UNICEF/WHO initiative Reduce mortality due to vaccine-preventable diseases by 2/3 by 2015 Reach 90% coverage by 1015 Introduce new vaccines (which?) Can we afford GIVS? Wolfson et al. (2008) try to answer this!

39 Investment in vaccines by governments and the private sector Vaccines the number-one priority at the Gates Foundation Prevent the deaths of some 7.6 million children under 5 from million children could be saved with the rapid introduction of a malaria vaccine beginning in 2014 Bill & Melinda Gates Foundation

40 Final Remarks on Vaccine Policy One of the most effective and equitable health preventive technologies Global Policy requires sound epidemiology, science, commitment and partnership Use of vaccines is key to their preventive success Addressing the safety and societal concerns is a priority
