  3. Disease Overview DISEASE PATHOGEN, TRANSMISSION & TARGET POPULATION* DISEASE PATHOGEN, TRANSMISSION & TARGET POPULATION1 • Disease Pathogen • Rabies Virus (lyssavirus) • Transmission • Usually dog bites in developing countries; animal to person via saliva from a bite • Incubation periods have been as short as 5-6 days, in the majority of cases is 20-60 days • Geographic Distribution • Most human cases are in rural areas of Africa and Asia • Disease Target Population • All ages are susceptible, however, rabies is most common in ages 5-15 years old, the majority of whom are male

  4. Rabies Disease Overview DISEASE IMPACT2,3 • Total Morbidity • >10 million suspected cases per year in developing countries • Rural poor and children are most at risk • Total Mortality • ~55,000 cases reported annually and thought to be grossly underreported with the majority of deaths occurring in Asia and Africa • Case fatality rate is 100% once clinical symptoms present (with exception of one known survivor to date) • Epidemic Potential • Human outbreaks can occur as a result of epidemics in the animal population and/or when a rabid animal bites multiple people • Disease Sequelae • Permanent neurological sequelae in the one survivor to date

  5. Rabies Disease Overview DISEASE BURDEN – GEOGRAPHIC DISTRIBUTION4 Note: “This figure is an unrealistic representation of the true epidemiological situation as a result of problems with reporting biases, e.g. dog rabies is endemic throughout Africa” - Partners for Rabies Prevention Informal Group (PRP)

  8. Rabies Disease Overview NON-VACCINE PREVENTION & TREATMENT INTERVENTIONS8 • Non-Vaccine Preventions • Control and vaccination of domestic dogs and wild carnivores • Treatment Interventions • Post-exposure prophylaxis rabies vaccination and passive immunoglobulin administration around the wound (to neutralize the virus before it enters the CNS) • After symptoms ensue there is no recognized effective treatment

  9. Rabies Disease Overview INEQUITIES8 • Inequity of Poor • Poor access to post-exposure prophylaxis and increased inability to control and vaccinate dogs exists in low socioeconomic areas • Gender Inequities

  14. RABIES Vaccine Landscape Analysis COST EFFECTIVENESS LITERATURE SUMMARY • Post-exposure rabies prophylaxis is estimated to prevent 330,304 (90% CI: 141,844 - 563,515) deaths in Asia and Africa. Rabies is responsible for an estimated 1.74 million (90% CI: 0.25M – 4.57M)DALYs. Global expenditure for rabies prevention is over $1 billion.16 • A 1996 study demonstrated that pre-exposure rabies prophylaxis for the international travelerwas worth$275,000 per case averted.17 • Cost comparison of rabies pre-exposure vaccination to post-exposure vaccination in Thai childrenshowed that pre-exposure vaccination was cost-effective when the dog bite incidence is 2% to 30% of the population.18

  19. Vaccine Need & Adoption Forecast GAVI-ELIGIBLE COUNTRY VACCINE NEED Vaccine Need: 49 VISP Scope: 49 • The vast majority of deaths due to rabies occur in Asia and Africa (WHO position paper, Dec07); the current countries in scope represent countries with high rabies incidence or countries in need of rabies education and vaccination with safe rabies vaccines (F. Meslin, WHO & D. Briggs, Alliance for Rabies Control)

  22. Vaccine Need & Adoption Forecast CURRENT COUNTRY SUPPORT AS PERCENT OF TOTAL NEED • Rabies experts provided estimate of current country-by-county vaccine usage as percent of total need* • Approximately 35% of total GAVI-eligible country vaccine requirements are currently being supported by countries themselves * F. Meslin, WHO & D. Briggs, Alliance for Rabies Control

  23. Vaccine Need & Adoption Forecast GAVI VACCINE FINANCING POLICY • As a matter of policy, GAVI does not replace country funds already allocated to rabies vaccines • However, most countries are under resourcing rabies vaccination due to: • High cost of vaccine and rabies immunoglobulin • Vaccine and immunoglobulin supply shortages • Therefore, GAVI would only plan to financially support the difference between actual vaccine need and percent of need currently covered by country • This incremental need assessment will be complicated given a country’s level of funding in any given year is influenced by many factors and may differ year on year • This analysis is focused on GAVI-eligible countries’ total need

  32. Additional Investment Opportunities BACKGROUND OF UNDERSTANDING • Although rabies has the highest case fatality rate of any disease known to mankind, preventing human rabies in reality is not a complicated issue as it is one of the easiest diseases to prevent • There are three basic steps to preventing human rabies: • Increase educational awareness activities to reduce exposures, increase professional expertise and improve diagnoses and surveillance • Administer prompt and appropriate post-exposure prophylaxis (PEP) when exposures do occur • Conduct preventative immunization (PreP) to protect the relatively few numbers of the populace that are living in high-risk, remote geographic locations with no access to PEP • It has been proven in many countries that if and when these three steps are instituted the number of human rabies deaths quickly and dramatically decreases

  33. Additional Investment Opportunities OPTION A* Pilot PEP in Select Countries To Demonstrate GAVI Impact • Experience over two decades has proven that reduced dose regimens for PEP are both efficacious and cost-effective • Updated Thai Red Cross (TRC) intradermal (ID) regimen or “2-2-2-0-2” is most cost effective PEP regimen recommended by WHO • TRC has increased access to vaccines in poor countries and has reduced the PEP cost per patient from 40 to 80% • Awareness as to the utilization and benefit of reduced dose regimens is lacking in most poor countries where it could be of great value • By piloting ID PEP in 4 select countries (2 in Asia & 2 in Africa), GAVI can demonstrate the health impact and cost reduction potential of this approach • With pilot PEP data, GAVI can then decide whether to extend support to all relevant GAVI-eligible countries • Estimated Total 5-Year Budget: $6M ($300K/year/country) • Vaccine + RIG: $2 million • Service Delivery: $400,000 annually • Social Mobilization/Education: $400,000 annually * Potentially eligible for GAVI Operations Research funding, if available

  34. Additional Investment Opportunities OPTION B Support Rabies Education Programs to Reduce Disease Burden • Rabies is one of few diseases that can be dramatically reduced through increased education • Activities to improve educational awareness is inadequate in most poor developing countries • Educational initiatives specifically targeted for national governments, professional public health staff and the general public are clearly the least expensive of investments that would result in the highest return in lives saved within the shortest amount of time. • Education for professionals in poor developing countries would include: • Use of intradermal (ID) administration for PEP • Dissemination of latest WHO recommendations • Increased awareness of source of rabies • Training on modern diagnostic tools currently available for rabies confirmation • Estimated 5-Year Budget per Country: $1.2M • Education materials development: $200,000 • Education and training: $200,000 annually

  35. Additional Investment Opportunities OPTION C Fund RIG Capacity Building To Eliminate Shortages and Reduce costs • Rabies immunoglobulin (RIG) is the most expensive component of rabies treatment needed for approximately 66% of all suspect bites • Strengthening the production of equine RIG and supporting the development of alternative technologies to replace equine RIG is critical for ensuring adequate supplies and lowering the current price • Estimated 5-Year Budget: $4M • Equine RIG: $3M • Monoclonal antibody preclinical and clinical testing: $1M
