7 7 Cx Ca is second to only breast cancer as the leading cause of cancer in women worldwide. 1 –Global prevalence: ~2.3 million –Global incidence: ~500,000 GLOBOCAN about cx ca deaths in developing countries –2002 = >80% of cx ca deaths –2008 = 88% –And by 2030 = >98% Nearly every minute of every day a woman is diagnosed with cx ca Cervical cancer claims younger lives than most cancers 1. Ferlay J, Bray F, Pisani P, Parkin DM. Lyon, France: IARC Press; 2004.

9 9 The number of life years lost to cx ca represents a hidden productivity loss in developing countries Women in developing countries contribute substantially more to the household economy than their male counterparts. Almost 75 percent of food production each year is a direct result of women's labor. Cervical cancer claims more years of women lives 1 –than any other cause in Latin America and the Caribbean Breast, lung or stomach cancers AIDS Tuberculosis Maternal Conditions –Than any other cancer in SubSaharan Africa and South-Central Asia Cause-specific total years of life lost among women aged 25–64 years for developing countries, in 2000. 1 1.

Available prevention technologies
24
Limits of primary prevention Primary prevention = protection before exposure = to limit acquisition of infection –Abstinence protects…while it lasts –Most human being will become sexualy active –Many with marriage –Condoms are good but far from perfect Most Canadian mother think their daughter will come forward before initiating sex life –Overestimate coitarche by 1 year = too late for maximizing benefits of HPV vaccine!

OTTAWA, Dec. 9, 2015 /CNW/ - After reviewing Canadian and international information regarding the safety of the HPV vaccine, Gardasil, Health Canada is informing Canadians that the benefits of using this vaccine continue to outweigh the risks. The overall evidence continues to demonstrate that this vaccine can be safely used and that there are no new safety risks associated with its use. Gardasil is authorized in 133 countries around the world and is used to protect against four types of Human Papilloma Virus (HPV types 6, 11, 16, and 18), which cause 70% of cervical cancers, 90% of genital warts, and 80-90% of anal cancers. Vaccines are authorized for sale by Health Canada only after undergoing rigorous reviews to ensure their safety, efficacy and quality. Once on the Canadian market, Health Canada and the Public Health Agency of Canada continue to monitor the safety of all vaccines. A review of the safety of Gardasil by Health Canada was triggered by media reports of autoimmune and cardiovascular diseases. The safety review by Health Canada concluded that there is no evidence of an increased risk of autoimmune or cardiovascular diseases. Recent international reports are in line with Health Canada's findings. Since its authorization in 2006, nearly 2 million Canadians, and more than 63 million people worldwide, have been vaccinated with Gardasil. Approximately 1800 people in Canada, which represents approximately 1 out of 1,000 Canadians, reported side effects following vaccination with Gardasil. These include light-headedness, dizziness, nausea, headache, fever, and pain, swelling or redness at the injection site. The side effects are known and described in the Canadian labelling information. The benefits of using the vaccine outweigh the risks and potential side effects http://www.hc-sc.gc.ca/dhp-mps/medeff/reviews-examens/gardasil- eng.phphttp://www.hc-sc.gc.ca/dhp-mps/medeff/reviews-examens/gardasil- eng.php

High NPV if done by HPV DNA More expensive / QALY Infrastructure does not exist in most LMIC And are more complex *QALY = quality adjusted life year
42
42 Synergistic not competitive HPV preventive strategies We have to remember that the bulk of disease will remain for a few years in the middle aged women that may require some protection. Adopting screening techniques that are more sensitive, specific and allow for extension of time between two screenings may permit resources to be allocated to vaccination programs

The political scene
45
45 WHO position statement on HPV vaccines HPV vaccination should be included in national immunization programs, provided that: prevention of HPV-related diseases constitutes a public health priority vaccine introduction is programmatically feasible sustainable financing can be secured cost effectiveness of vaccination strategies is considered The primary target population is likely to be girls within the age range of 9-10 through to 13 HPV WHO position paper, WER 10Apr, No. 15, 2009, 84, 117-132
46
46 United Nations high-level meeting on noncommunicable disease prevention and control To shape the international agenda –19-20 September 2011, NY, USA –NCDs – like cancers account for over 63% of deaths in the world today. –NCDs kill 9 million/yr people under 60. –Socio-economic impact is staggering. –This is only the second time in the history of the UN that the General Assembly meets on a health issue the first issue was AIDS
47
47 Possible linkages between non-communicable diseases and some communicable diseases, such as HIV/AIDS, call for the integration Loss of productivity that threatens the economies of Member States may have a direct impact on the achievement of the internationally agreed development goals, including the Millennium Development Goals Recognize the importance of strengthening local, provincial, national and regional capacities to address and effectively combat non-communicable diseases Promote increased access to cost-effective vaccinations to prevent infections associated with cancers, as part of national immunization schedules; Promote increased access to cost-effective cancer screening programmes, as determined by national situations; Promote the inclusion of non-communicable disease prevention and control within sexual and reproductive health and maternal and child health programmes, especially at the primary health-care level, as well as other programmes, as appropriate

59 General challenges to all new vaccines intro in LMICS Taking into consideration what has been learned and accomplished to date –Competing health challenges, including several new vaccines (PCV, rotavirus, HPV) –However, non-GAVI-eligible LMICs may lack dedicated funding sources and ability to implement (vaccine & delivery costs) and sustain the introduction of these new vaccines –Variable country capacity with respect to education, advocacy, & institutional capacity (including national immunization technical advisory groups, BOD studies, capacity to evaluate vaccine cost effectiveness, procurement & delivery capacity, etc). –Uneven political will in some countries
60
60 Challenges specific to the introduction of HPV vaccine Continued need for education and advocacy for HPV prevention Build political will for HPV disease prevention Need for countries to develop well-suited national comprehensive strategies for CxCa prevention that take into consideration individual country capacity and resources Further optimize HPV vaccine delivery approaches that take into consideration existing health infrastructure, resources –Identify the most cost-effective delivery strategy Respect any cultural sensitivities about a vaccine program that targets adolescent females only
61
61 Financing vaccines Various bilateral assistance programs exist The GAVI Alliance will begin offering HPV vaccine at a subsidized rate for the poorest countries in the world –as low as US $0.20 vaccine per dose co-pay for a fixed period The PAHO EPI Revolving Fund also has negotiated low prices for its member countries.

67 Integrating vaccination and screening strategies Strategies that integrate HPV or cervical cancer screening and HPV vaccination are complex and should be carefully deployed. It is essential that governments and resources are not pulled apart into two separate programs (vaccination and screening) but proper attribution of resources is of utmost importance. In young women, cervical cancer screening should not be done too early and vaccine should be prioritized early in adolescence.

73 Challenges to implement HPV prevention There may be challenges to implement screening or HPV immunization programming in LMIC But none of these challenges should be considered insurmountable. Many LMIC have decided with success to adopt HPV prevention agenda despite prevailing pessimism. Not acting on this issue perpetuated inequity in STI and cancer prevention.

76 Decreasing maternal mortality in developing countries. Our success reducing maternal mortality is cause for great hope That with similar investments These same mothers having been saved during pregnancy Will be protected 10 or 20 years later in life when they face the threat of cervical cancer.

77 Would HPV vaccine be the best of all preventive activity of public health yet? Cervical cancer prevention by vaccine and screening might be the most efficient way to fight the inequities about women’s health issues Our breast cancer and HIV colleagues are so jealous as they do not have such a powerful vaccine and versatile testing scheme. Moment of reflexion
