2 Background Vaccine Investment Strategy June: Board agrees to use reduced overall disease burden as portfolio objective November: Board recognizes need for comprehensive vaccine investment strategy October: Board endorses the portfolio: HPV, Japanese encephalitis, rubella and typhoid November, GAVI Board opened funding window for HPV country proposals provided: Acceptable price for vaccine Countries have demonstrated ability to deliver vaccine Board also requested to develop HPV demonstration projects

3 Two Pathways for HPV vaccine intro Country applications Country applications Not approved Natnl Intro (Pathway 1) Demonstrated ability needed Demo Program (Pathway 2) Not approved Approved Approved National Intro Scale-up Go/No- Go? Go No Go Not Ready Applications from another pathway

7 Application Requirements for National Intro Demonstrate to have a DTP3 coverage of at least 70%. Identify a single year target vaccination cohort within the target population of 9-13 year old girls. Have demonstrated ability to deliver a complete multi-dose series of vaccines to at least 50% of the target vaccination cohort in an average size district (preferably comprising urban and rural areas) using a strategy similar to the one proposed for national HPV vaccine delivery. Provide a report on the costing analysis of the proposed delivery strategy. GAVI will not provide financial support for recurrent operational costs. HPV operational costs relatively high. Clarify plans for communication and social mobilisation reflecting unique needs of the programme. If possible, national roadmap or strategy for establishing or strengthening a national comprehensive approach to cervical cancer prevention and control.

8 Overview of HPV Strategic Demand Forecast v5.1 No supply or financial constraints assumed 40 GAVI supported introductions by 2020 Up to 21 countries are forecasted to run demonstration projects with GAVI support by 2015; up to 36 for 2020 GAVI supported demand to peak at 41m in 2026 Up to 32m girls immunized with HPV vaccines by 2020 with GAVI support

9 SDF version 5.1 base-case assumptions (1/2) Finance and support Target population No global financial or supply constraints included in the base-case strategic demand forecast. NVS applications evaluated on national metrics (no separate state / subnational applications). Co-financing policy revision (December 2010) fully incorporated. Eligibility for GAVI support based on GNI projections from 2010 World Bank actuals and GDP per capita growth rate ( , IMF). Girls aged 10 years, based on 2010 UN population prospect, medium variant. India population at state level based on 2011 Indian census (projected with UN growth rate). Introduction Introduction timing as per HPV sub-team inputs received in June 2012 Countries that have experience demonstration project assumed to be early adopters for HPV vaccination. From 2009 to 2011, both Gardasil and Cervarix have been used in pilot projects via donation in a number of countries.

10 SDF version 5.1 base-case assumptions (2/2) Products Coverage Uptake Logistics All products WHO pre-qualified and with suitable presentation. Mix of international and developing countries suppliers: Cervarix from GSK and Gardasil from Merck currently available; new vaccines from developing countries expected. Schedule = 3 doses at 10 years of age (female only) with no booster. Presentation = 1- and 2-dose liquid vials. Reference coverage: linear extrapolation of DTP2 from WHO/UNICEF estimate of DTP3/1 projected based on standard AVI WHO coverage forecasting rules. Girls enrolled in school to reach reference coverage. Girls not enrolled in school to reach 70% of reference coverage in BASE CASE SCENARIO Coverage: (Girls in school)*(ref. coverage) + (Girls out of school)*(ref. coverage)*0.7 Time to match reference coverage slower than HepB/penta analog (new vaccine with no overlap): 36 months for small countries / 48 for medium or large countries / 60 months for very large countries. Wastage = mixture of 5% and 10% based on product presentation, 1- and 2-dose vials. Buffer stocks = 25% of demand increase. Cold chain up-scaling and ongoing financing available at central and local levels in all countries. Scenario(s) Country request scenario assumes immediate uptake and uses DTP1 as analogue High scenario assumes acceleration of 1 year among early adopters (depending on experience with demonstration projects) and 2 years acceleration among medium and late adopters Low scenario applies 2 year delay across all countries that have not yet introduced HPV vaccines 10

17 General Framework At least one district (equivalent to an EPI administrative unit), with maximum of 15,000 eligible girls (tbc). A single year of age or a single school grade (with provisions for reaching out-of-school girls of similar age) cohort within the target population of 9-13 year old girls. Multi-disciplinary technical advisory group (leverage existing TAG, ICC, NiTAG, if applicable). Two year programme. Planning Vaccine Introduction Evaluation Testing of integrated adolescent health package Year 1: Demo project implementation Year 2: Bridging

18 Demonstration projects would take place two years before routine introduction in a small population Project details Target population Coverage Vaccine Start 2 years before routine introduction 2 years duration Average % of 10y old girls from previous successful demonstration projects (Merck, PATH) ~1-3%, which corresponds to one district 1,000 27,000 girls per country Reference coverage: linear extrapolation of DTP2 from WHO/UNICEF estimate of DTP3/1 projected based on standard AVI WHO coverage forecasting rules. Girls enrolled in school to reach reference coverage. Girls not enrolled in school to reach 70% of reference coverage. Coverage: (Girls in school)*(ref. coverage) + (Girls out of school)*(ref. coverage)*0.7 Schedule = 3 doses at 10 years of age (female only) with no booster. Presentation = 1- and 2-dose liquid vials Wastage = 5% and 10% based on product presentation. Buffer stocks = none
