29 Where do we want to go??

30 lobal lliance for accines & mmunization G A V I

31 Is a global alliance between PRIVATE and PUBLIC sectors committed to saving CHILDREN’S lives & protecting peoples health by increasing access to immunization in peer countries. Bakry, 2011

35 FACTSFACTS 9 million children die before their 5 th birthday every year 2.4 million children die from diseases that are vaccine preventable (That is one child every 20 seconds!) 24 million children in the world remain unvaccinated!! Bakry, 2011

36 Causes of under five child deaths in low income countries Bakry, 2011

37 GAVI supports 72 countries AfghanistanAngolaArmeniaAzerbaijan BangladeshBeninBhutanBolivia Burkina FasoBurundiCambodiaCameroon Central African RepublicChadComoros CongoDem Republic of Côte d'IvoireCuba DjiboutiEritreaEthiopiaGambia GeorgiaGhanaGuineaGuinea Bissau GuyanaHaitiHondurasIndia IndonesiaKenyaKiribatiKorea DPR Kyrgyz RepublicLao PDRLesothoLiberia MadagascarMalawiMaliMauritania MoldovaMongoliaMozambiqueMyanmar NepalNicaraguaNigerNigeria PakistanPapua New Guinea RwandaSão Tomé SenegalSierra LeoneSolomon IslandsSomalia Sri LankaSudanTajikistanTanzania Timor LesteTogoUgandaUkraine UzbekistanViet NamYemenZambia Zimbabwe ½ the worlds population Bakry, 2011

39 Pentavalent (DPT, HBV, Hib) Rotavirus vaccine Pneumococc al ?? GAVI supporting new vaccines Bakry, 2011

40 Vaccine preventable deaths and the global immunization vision and strategy, Priorities in Public Health interventionsVPD deaths can be averted if existing vaccines used at full potentialIn 2002 deaths from diseases for which vaccines are WHO recommended<1,000 children < 5 died from polio4,000 children died from diphtheria15,000 children died from yellow fever198,000 children died from tetanus294,000 children died from pertussis386,000 children died from (Hib) Hemophilus influenza type B540,000 children died from measles Bakry, 2011

42 Vaccination and decline of Hib disease in Finland Bakry, 2011

43 GAVI’s Strategy GAVI’s ability to secure predictable long-term funding and prompt demand for vaccines Manufacturers (including in developing countries) have increased commitment to providing suitable vaccines for developing countries Increased competition for vaccine productionDecreased prices of GAVI supported vaccines Bakry, 2011

44 The GAVI alliance strategy Bakry, 2011

45 HSS: Health System Strengthening six key components

46 Health service delivery: a network of health facilities to provide access to primary & secondary care. Bakry, 2011

47 Health workers: in the right place at the right time with training, experience & incentives Bakry, 2011

48 Health information systems: to generate quality data and to measure what is being done & achieved Bakry, 2011

49 Logistics & supply systems: so that drugs, equipment and fuel are available Bakry, 2011

50 Health financing: to raise sufficient funds for health & improve financial risk protection Bakry, 2011

51 Leadership & governance: to ensure that strategic policy frameworks exist and there is proper accountability and oversight Bakry, 2011

52 Egypt is strong in this area because of good infrastructure of existing high vaccination coverage Bakry, 2011

53 Vaccine Research & the future

54 Vaccines by Period of Development 18th Century Smallp ox (1798) 19th Century RabiesHog choleraDiphtheria Antitoxin Cholera Plague Typhoid (1896) Early 20th Century BCG tuberculosis Pertussis (1926) Diphtheria (1923) Influenza (1936) Tetanus toxoid (1927) Yellow fever (1935) Rickettsia (1936) Influenza A (1936) Post WW II Yellow Fever (1935) Influenza (1945) Diphtheria Typhoid (1952) Polio salk (1955) Meningococcus (1962) PolioSabin (1963)Measles (1963)Mumps (1967) Tick-borne encephalitis rubella (1970) Anthrax (1970)MMR (1971) Adenovirus Rabies (1980, human) Hemophilus influenza Hepatitis B (1987)Typhoid (1992)Salmonella Japanese encephalitis Hepatitis B (1981)Varicella (1995) Pertussis acellular (1993) Lyme disease (1998) Hepatitis A (1995)Rotavirus (1998) Pneumococca l Meningococc al disease InfluenzaParainfluenza Human papillpmavirus (HPV) Future H. Pylori Streptococ uss HIVHepatitis C adenoviruse s Bakry, 2011

55 Introduction of first generation of vaccines used on humans Originals 1798 Smallpox 1885 Rabies 1897 Plague 1923 Diphtheria 1926 Pertussis 1927 Tuberculosis (BCG) 1927 Tetanus 1935 Yellow Fever After WW II 1955 Injectable Polio Vaccine (IPV) 1962 Oral Polio Vaccine (OPV) 1964 Measles 1967 Mumps 1970 Rubella 1981 Hepatitis B Bakry, 2011

56 Vaccines used by the expanded Programme on Immunization (EPI) From 1974 onwards BCG Polio DTP Measles* Added Later Yellow fever (in endemic countries Hepatitis B MMR used in industrialized countries and now in many developing countries Bakry, 2011

57 Stages of vaccine development Vaccine development proceeds through discovery process engineering toxicology and animal studies to human phase I, II and III trials. The process can take more than 10 years, depending on the disease Bakry, 2011

58 An ideal Vaccine should be Good immune response Both cell mediated immunity and antibody responses Immunity is long lived Single dose Safety Danger of reversion to virulence, or severe disease in immunocomprised Stability Organisms in the vaccine must remain viable in order to infect and replicate in the host Vaccine preparations are therefore very sensitive to adverse storage conditions Maintenance of the cold chain is very important Expense Cheap to prepare Bakry, 2011

59 Calculated Cost effectiveness for any Vaccine No of doses of vaccine given Cost of Vaccination (doses + admin.) No of Episodes of disease prevented e.g Otitis Media -Saving Pneumonia -Saving Invasive Diseases -Saving No life Years Saved = Net Cost of Vaccine Program Net Cost of Vaccine Program = Cost per Life –Year Saved No life Years Saved

60 Pneumococcal Vaccine (1000 children)

62 Conclusions Lobbying for improving states of vaccinations in Egypt. Start by introduction of Hib as part of the national program Then gradually introduce other vaccines according to priorities Bakry, 2011

63 Possible candidates Varicella Hepatitis A Rota Pneumococcal Bakry, 2011

64 Funding Approach MoH for co-ordination of plans Approach GAVI to renew status of Egypt Negotiate prices of vaccines with producers Approach civil society associations for funding start ups and maintenance Cost sharing with the public Bakry, 2011

71 WHO/UNICEF’s current vaccines Bakry, 2011

72 Cold chain monitor card: upon arrival to a health clinic, vaccines are stored in refrigerators and temperatures recorded on a chart. The temperatures are monitored and recorded twice a day to ensure that a safe temperature is maintained Vaccine vial monitor (VVM): the vaccine vial monitor consists of a temperature sensitive label placed on each vial that registers cumulative heat exposure for that vial. GAVI resolved that all vaccines be purchased by the Vaccine Fund after 2003 will include VVM (immunization focus, July 2003, GAVI newsletter) Freeze watch: in the freeze watch, a vial with a red liquid that bursts and stains a white placard if exposed to temp. below zero for > 1 hour is packed with DTP, TT (freezing pt C) (WHO, vaccines-cold chain, 2005)
