1 Building blocks to success in malaria elimination

2 Proven Successes in Global Health – case studies
Eradicating smallpox Preventing HIV/STDs in Thailand Trachoma in Morocco Health in Mexico Infant diarrhea deaths in Egypt Onchocerciasis in Africa Polio in the Americas TB in China Safe motherhood in Sri Lanka Guinea worm control in Africa and Asia Tobacco use in Poland Measles in Southern Africa Hib in Chile and Gambia Iodine deficiency in China Flouridation in Jamaica Chagas in Southern Cone through vector control Fertility in Bangladesh Source: Levine, R., Millions Saved: Proven Successes in Global Health, Center for Global Health, What Works Working Group, 2005

3 Proven Successes in Global Health – common elements
Technical consensus about the appropriate biomedical or public health approach Technological innovation with an effective delivery system, at a sustainable price Predictable, adequate funding from both international and local sources Political leadership and champions Good management on the ground Effective use of information This slide shows common themes that were identified in the analysis, Millions Saved by Ruth Levine of the Center for Global Development, which analyzed 17 successes in global health. From this analysis, six “Elements of Success” emerged – common features of most or all of the 17 case studies. The MV TRM process was originated to develop the technical consensus described in the first bullet and stimulate technological innovations described in the second bullet. However, if we are successful as a community in developing an effective roadmap, the other four elements of success will also come. The Malaria Vaccine TRM has the potential to cultivate these elements of success for malaria vaccines.

4 Transformations: Control vs. Elimination/Eradication
Goal - Control Goal – E/E Prevent death – RTS,S Case management Risk groups such as malaria in pregnancy, severe malaria Scale up existing interventions – LLINs, ACTs, IRS Prevent transmission – TBVs, SERPAC, etc. Simplify toolbox – single dose treatment, avoid and prevent resistance Make tough decisions Refocus R&D targets MalERA

11 Real time mHealth monitoring of ACT supply chains..
We have good drugs for malaria! But a continuing challenge of global, national and local responses to antimalarial drug procurement and supply chain system realities.

13 Research Priorities: Surveillance - Response Systems (SRS)
Dynamic mapping of „pockets“ of transmission and/or reintroduction Capturing population dynamics Analyses of M&E data and modeling to optimize SRS Parasite – Man – Vectors Sampling in space and time Design and validate with use of (i) evidence from programs and (ii) modeling (intervention mixes) effective response packages tailored to different transmission settings and levels Use of new technologies (m/e-health, diagnostics) Validation, validation, validation…alongside with programs

Field implementation Guide published (English and French) 3 workshops (2012, 2013) have been organized by WHO in collaboration with the UCAD / LSHTM, and RBM/WARN that provided countries with support and to guide SMC planning and implementation. 9 countries have adopted and added it in their strategy Large scale implementation yet to start due to funding constraints, small scale implementation ongoing in a few countries (Mali, Senegal, Niger, Nigeria) Challenges in sourcing pre-qualified medicines Based on implementation plans developed by the WARN eligible countries (9 countries), 19 million children can potentially benefit from SMC during the next three malaria seasons (up to 2016).

This is MVI’s portfolio of vaccine projects today. As the products move from the left to the right, they become closer to reality. [For the world as whole, there are about 40 malaria vaccine projects in either the preclinical or clinical phase.] Since 2003, MVI has moved more than three dozen projects through the pipeline, including 12 into human testing. One of them has made it to the last stages of development before licensure: RTS,S. Phase 3 trial is designed to confirm and safety and efficacy of a vaccine, to confirm the results of previous, but much smaller studies. This is a major achievement and a testament to the power of the product development partnership model. RTS,S, which is under development through a partnership between the MVI program and GSK Vaccines, is the only vaccine candidate to advance so far in the development pipeline.
