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

• 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

High Cervical Cancer Disease BurdenJustification 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)

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 subSaharan Africa cervical cancer working group expert
panel year 2008

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 2009.
 GSK paid for Vaccine Registration Dec 2009
 Vaccine registration 8 August 2012
 Cervarix launch, 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

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
