WHO/UNICEF estimates for HPV vaccination coverage from 2010 to 2019 are analyzed against the backdrop of the 90% coverage target for HPV vaccination by 2030 set in the recently approved global strategy for cervical cancer elimination as a public health problem. As of June 2020, 107 (55%) of the 194 WHO Member States have introduced HPV vaccination. The Americas and Europe are by far the WHO regions with the most introductions, 85% and 77% of their countries having already introduced respectively. A record number of introductions was observed in 2019, most of which in low- and middle- income countries (LMIC) where access has been limited. Programs had an average performance coverage of around 67% for the first dose and 53% for the final dose of HPV. LMICs performed on average better than high- income countries for the first dose, but worse for the last dose due to higher dropout. Only 5 (6%) countries achieved coverages with the final dose of more than 90%, 22 countries (21%) achieved coverages of 75% or higher while 35 (40%) had a final dose coverage of 50% or less. When expressed as world population coverage (i.e., weighted by population size), global coverage of the final HPV dose for 2019 is estimated at 15%. There is a long way to go to meet the 2030 elimination target of 90%. In the post-COVID era attention should be paid to maintain the pace of introductions, specially ensuring the most populous countries introduce, and further improving program performance globally.

More than 90% of cervical cancer deaths occur in low- and middle-income countries (LMICs), which have limited capacity to mount the comprehensive national screening and precancer treatment programs that could prevent most of these deaths. The development of vaccines against the human papillomavirus (HPV) has dramatically altered the landscape of cervical cancer prevention. As of mid-2020, 56 LMICs (41% of all LMICs) have initiated national HPV vaccination programs. This paper reviews the experience of LMICs that have introduced HPV vaccine into their national programs, key lessons learned, HPV vaccination sustainability and scale-up challenges, and future mitigation measures. As international guidance evolved and countries accumulated experience, strategies for national introduction shifted with regard to target groups, delivery site and timing, preparation and planning, communications and social mobilization, and ultimately monitoring, supervision and evaluation. Despite the successes that LMICs have been able to achieve in reaching large proportions of eligible girls, there are still considerable challenges countries encounter in overcoming rumors, reaching out-of-school girls, completing the vaccine series, estimating target populations, monitoring program performance, and assuring vaccination sustainability. New opportunities, such as the entry of additional vaccine manufacturers and ongoing studies to evaluate one-dose delivery, could help overcome the outstanding barriers to higher coverage and financial sustainability. Effective use of the experience to date and advances on the horizon could enable all LMICs to move towards the coverage levels that are needed to achieve eventual elimination.

A WHO global strategy launched in November 2020 sets out an ambitious pathway towards the worldwide elimination of cervical cancer as a public health problem within the next 100 years. Achieving this goal will require investment in innovative approaches. This review aims to describe integrated approaches that combine human papillomavirus (HPV) vaccination and cervical cancer screening in low- and middle-income countries (LMIC), and their efficacy in increasing uptake of services. A systematic review was conducted analyzing relevant papers from Embase, Medline, CINAHL and CAB Global Health databases, as well as grey literature. Narrative synthesis was performed on the included studies. Meta-analysis was not appropriate due to the heterogeneity and nature of included studies. From 5,278 titles screened, 11 uncontrolled intervention studies from four countries (from Africa and east Asia) were included, all from the past 12 years. Four distinct typologies of integration emerged that either increased awareness of HPV and/or cervical cancer screening, and/or coupled the delivery of HPV vaccination and cervical cancer screening programs. The synthesis of findings suggests that existing HPV vaccination programs can be a useful pathway for educating mothers and other female caregivers about cervical cancer screening; through in person conversations with care providers (preferred) or take-home communications products. Integrated service delivery through outreach and mobile clinics may overcome geographic and economic barriers to access for both HPV vaccination and cervical cancer screening, however these require significant program and system resources. One study promoted HPV vaccination as part of integrated service delivery, but there were no other examples found that examined use of cervical cancer screening platforms to promote or educate on HPV vaccination. This review has demonstrated gaps in published literature on attempts to integrate HPV vaccination and cervical cancer screening. The most promising practices to date seem to relate to integrated health communications for cervical cancer prevention. Future research should further explore the opportunities for integrated health communications to support the efforts towards the new global cervical cancer elimination agenda, and costs and feasibility of integrated service delivery for underserved populations.

Developing countries disproportionately suffer from the burden of cervical cancer yet lack the resources to establish systematic screening programs that have resulted in significant reductions in morbidity and mortality in developed countries. Human Papillomavirus (HPV) vaccination provides an opportunity for primary prevention of cervical cancer in low-resource settings through vaccine provision by Gavi The Vaccine Alliance. In addition to the traditional national introduction, countries can apply for a demonstration program to help them make informed decisions for subsequent national introduction. This article summarizes information from approved Gavi HPV demonstration program proposals and preliminary implementation findings. After two rounds of applications, 23 countries have been approved targeting approximately 400,000 girls for vaccination. All countries are proposing primarily school-based strategies with mixed strategies to locate and vaccinate girls not enrolled in school. Experiences to date include: Reaching marginalized girls has been challenging; Strong coordination with the education sector is key and overall acceptance has been high. Initial coverage reports are encouraging but will have to be confirmed in population based coverage surveys that will take place later this year. Experiences from these countries are consistent with existing literature describing other HPV vaccine pilots in low-income settings.
