HPV Vaccine Introduction Demo Project in Zimbabwe Where Are We? By M.N Munyoro, WHO/ NPO/EPI Presentation to The Health Cluster 12/11/13
Presentation Outline • Leading Causes of Cancer Morbidity and Mortality in the Region • Cervical Cancer Disease Burden • Background to HPV Application • Advocacy Social Mobilization and Communication • Prevention • Proposed Vaccination Strategy in Zimbabwe • HPV Vaccines • Lessons Learnt from Other countries and Way Forward
Cancer of the Cervix is an abnormal growth in the lower, narrow part of the womb • The vast majority of cervical cancers are caused by: • Infection with the Human Papilloma Virus (HPV) • Risk factors include: • Smoking • Immunosuppression, e.g. HIV infection • Unhealthy diet (low in fruits/vegetables) • Long term oral contraceptives use • Multiple full term pregnancies • Multiple partners
Natural History of HPV infection Acute infection 2° and 3° Intervention: Screening/ Treatment 1°Intervention: HPV Vaccination 2°Intervention: Screening/Treatment Immune Chronic infection Precancerous lesion Cervical cancer Susceptible Timeframe following acute infection: 5-15 years 20+ years 2 years • Most HPV infections are asymptomatic • >90% of new infections (including those with high risk types) clear or become undetectable within 2 years • But persistent infection with high risk types leads to cervical cancer
The leading cause of cancer morbidity and mortality in this Region • World-wide estimated 530,000 new cases of cervical cancer in 2008 • 14% of these occurred in Africa • Of all cancers, cervical cancer is the most common in Africa, followed by breast cancer • The death ratio in Africa is 67%, while it is 52% globally Globocan 2008: Factsheets
Annual number of deaths from Caner of Cervix by age group, Globocan 2008
High Cervical Cancer Disease Burden-Justification for HPV Application • In Zimbabwe Cervical Cancer remains the leading cause of morbidity among all the cancers. • In 2009 cervical cancers contributed to 19% (669 cases) of all new cancers and 13 % (134) of all cancer deaths.(Cancer Registry 2009)
Burden of Cervical Cancer Zimbabwe • How many cases are diagnosed each year? - Approx 1000 new cases / year (32% all cancers) • What is the incidence of disease? -ASR 47/100 000 • Which age groups are most affected? -40 to 49 years • What are the annual death rates from cervical cancer? - 33 / 100 000
Background Information • National Cancer Registry established in 1985 • HPV Vaccine Advocacy Group was formed in 2008. • Zimbabwe-specific HPV vaccine guidelines formulated at the stakeholders workshop on 16th April 2009 • Guidelines based on the model HPV vaccine recommendations for sub-Saharan Africa by the sub-Saharan Africa cervical cancer working group expert panel year 2008
BackgroundContd • HPV Vaccine Advocacy workshop with stakeholders was held in June 2009 • During the workshop, MoHCW re-affirmed its commitment to introduce HPV vaccine as part of the overall fight against cancer of the cervix • HPV Vaccine introduction officially approved with HPV Vaccine Launch in October 2009. • GSK paid for Vaccine Registration Dec 2009 • Vaccine registration 8 August 2012 • Cervarixlaunch, 31 October 2012
Events leading to HPV application • March 2012 communication from GAVI advising interested countries to apply • ICC meeting convened to support the need to apply • Ministry officials (NCD, CH, Reproductive Health) attended WHO supported regional meeting in SA on HPV Demo projects implementation- May 2012 • Application process started with EPI team in the lead. (Team included CAH, RH,EPI MoHCW staff including HPO, EPI partners ,WHO,MCHIP, UNICEF,NCD officer). Ministry of Education was extensively consulted.
Events contd • GAVI HPV vaccine demo application June 2012 • October 2012 Zimbabwe submitted its first application which was not successful-GAVI requested for some clarifications • GAVI response required some clarifications centered on : - Need to involve Civic Organization Groups • Need to detail how to reach the HPV vaccine target group bearing in mind that this group is outside the usual EPI target group
Events contd • Clarifications submitted and HPV application approved • GAVI HPV vaccine demo approval -June 2013 • MOHCC Strategic Advisory Group on HPV vaccine introduction was recently appointed by PS • First SAG meeting on HPV Vaccine introduction convened.
Advocacy Social Mobilization and communication • ACS to be carried out among key community opinion leaders for acceptance of the new vaccine. • The sero-prevalence of HIV/AIDS is high in Zimbabwe, among which 60% are women. Cervical cancer is more prevalent in immuno suppressed HIV positive women and progresses faster in these women
Advocacy Social Mobilization and communication: • Questions likely to arise from the community in relation to the HPV vaccination : -Why give HPV vaccine to 10 year olds only? -Why not give HPV to Boys? -Why not give HPV to Women -Why in two Districts only
The core of Cervical Cancer “Primary Prevention” is immunization of girls against HPV infection • HPV vaccination: • Girls age 9 – 13 years • Priority given to areas with low access to cervical cancer screening • So far Rwanda and Lesotho included it in national programs • About 8 other countries in demo phase • Other interventions: • Health information and warnings about tobacco use • Sexuality education tailored to age and culture • Condom promotion/provision for those sexually active • Male circumcision Cape Verde Seychelles Comoros Mauritius 2 Countries wide introduction : Rwanda and Lesotho Nationwide introduction Demonstration project in 2013 Not yet in country EPI Not AFR
Secondary prevention Entails screening & early diagnosis • Currently the best chance of saving lives. • Traditionally cervical cytology (Pap smear) is known to have reduced incidence in developed countries. • Visual inspection with acetic acid or iodine is better alternative in this region followed by cryotherapy.
Secondary Prevention contd • HPV testing for high risk HPV type (e.g. HPV 16; 18 and others) is available in the Region. • 15% of countries in the Region have capacity to conduct Acetic acid visualization whilst 25% have capacity to carry out Cervical cytology
WHO Position Paper on HPV Vaccine - 2009 • HPV vaccination should be introduced into national immunization programmes • where prevention of cervical cancer and other HPV-related diseases is a public health priority and • where vaccine introduction is programmatically feasible and financially sustainable. • Countries should prioritize achieving high coverage in the primary target population of 9 to 13 year old girls.
WHO Position Paper on HPV Vaccine (2009) Other considerations for HPV vaccination: • Introduce as part of a coordinated strategy to prevent cervical cancer and other HPV-related disease. • Prioritize populations who are likely to have less access to cervical cancer screening later in life. • Seek opportunities to link vaccine delivery to other health services and programmes targeting young people. • Do not divert resources from effective cervical cancer screening programmes.
Proposed Vaccination Strategy in Zimbabwe • In view of the age of girls in and out of school in Zimbabwe, a mixed strategy (school-based, health facility-based and outreach) approach. • A total of 4 441 10 year old girls, is targeted. • GAVI will support the purchase of the HPV vaccine and injection materials at a total cost of $159 500 for two years and GOZ and partners will meet the remaining costs.
Vaccination strategy Contd • Each child will be expected to receive 3 doses for full protection; -First dose to be given in April 2014 then ---second dose in May 2014 - 3rd dose in October 2014. • Demonstration project will be followed up with a national roll out of HPV
Vaccination Strategy Contd • Cervical Cancer screening services are currently in the urban setting in both private and public health sector which marginalizes the rural women. • Plans are in place to roll-out cervical cancer screening and treatment services to provincial and district hospitals which to a larger extent are made up of rural populations.
HPV Vaccines • Two vaccines currently available, widely licensed, and WHO prequalified: • Cervarix® (bivalent): Prevents precancerous lesions from HPV types 16 and 18 • Gardasil®/Silgard® (quadrivalent): Prevents precancerous lesions from HPV types 16 and 18 and anogenital warts from HPV types 6 and 11 • Up to 30% of all cervical cancer cases caused by HPV types other than 16 and 18, so these vaccines do not eliminate -need for future cervical cancer screening • Both vaccines require 3 doses administered over 6 months • Both vaccines have excellent safety profiles
HPV Vaccines(continued) • Both vaccines demonstrate best efficacy in individuals HPV-naïve to the vaccine types so best to vaccinate girls prior to initiation of sexual activity (target is 9-13 year old girls) • For both vaccines, younger girls have higher immune responses than 15 to 26 year old females • There is no evidence of waning protection over time for either vaccine (post-vaccination follow-up period exists up to 9 years) • Small studies in HIV-infected persons show that HPV vaccine is safe and immunogenic but duration of protection is unknown
Some lessons from countries who have introduced HPV(Tanzania) • Adequate sensitisation, to inform the public and to dispel rumours. • Improved and timely school record keeping. • Adequate training and resources for health workers (including vaccine cold storage).
Way Forward • Preparations for HPV introduction have started and to be intensified as from 4th quarter 13 • Two demonstration project districts have been identified-Marondera and Beitbridge • Need for TA (HQ,AFRO,IST) support in planning, implementation, monitoring and evaluation cannot be overemphasized
Conclusion • Smooth implementation of the demonstration project will create a good environment for the national roll out • Involvement of the community based organisations will also enhance community ownership of the project • Partner collaboration in the process is of Paramount importance • Advocacy and communication and social mobilisation activities also need to be emphasised before and during implementation
