Presentation Outline 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
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 Cancer of the Cervix is an abnormal growth in the lower, narrow part of the womb
Natural History of HPV infection Susceptible Acute infection Chronic infection Precancerous lesion 1°Intervention: HPV Vaccination Immune Cervical cancer Timeframe following acute infection: 5-15 years 20+ years 2 years 2°Intervention: Screening/Treatment 2° and 3° Intervention: Screening/ Treatment 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 % 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)

Cervical Cancer in Zimbabwe Cervical Cancer in Zimbabwe
Background Information Background Information National Cancer Registry established in 1985 HPV Vaccine Advocacy Group was formed in 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
Background Contd Background Contd 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 GSK paid for Vaccine Registration Dec 2009 Vaccine registration 8 August 2012 Cervarix launch, 31 October 2012
Events leading to HPV application 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 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 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 Cape Verde Mauritius Seychelles Comoros Nationwide introduction Not yet in country EPI Not AFR Demonstration project in Countries wide introduction : Rwanda and Lesotho 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
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 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 year old girls, is targeted. GAVI will support the purchase of the HPV vaccine and injection materials at a total cost of $ 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 rd dose in October 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 Way Forward Preparations for HPV introduction have started and to be intensified as from 4 th 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 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
