Methods

Data integration and quality control

Data for key indicators about cervical cancer and HPV in WHO member states was compiled and standardized by the Department of Immunization, Vaccines, and Biologicals, World Health Organization. Data were collected by WHO staff from public sources and from studies conducted by partner institutes. For example, the HPV vaccination impact model was developed by researchers at the London School of Tropical Medicine and Hygiene, literature reviews on prevalence of screening and HPV were conducted by the HPV Information Centre (Institut Català d'Oncologia, ICO and the International Agency for Research on Cancer, IARC), and global cancer burden estimates were obtained by the IARC. All data were integrated into one data workbook by WHO staff and shared with Project Tycho staff at the University of Pittsburgh. The data were checked for quality and consistency and loaded in to a relational database. An online graphical user interface was then designed and developed to display all available data for each country. The complete lists of data definitions and data sources are provided below.

Indicator Category Definition Notes Availability
1 Cervical Cancer Age-standardized Incidence (per 100,000) Summary Statistics Country value compared with average values for global, WHO region, and country income group. All countries for which data existed were included in group averages, as provided by a meta-analysis from the HPV Information Centre. For income group average, countries were divided into four income groups according to the World Bank, based on gross national income (GNI) per capita. Low-income groups are defined as those with a GNI per capita of $1,025 or less; lower middle-income groups have a GNI per capita between $1,026 and $3,995; upper-middle income groups have a GNI per capita between $3,996 and $12,375; high-income groups have a GNI per capita of $12,376 or more. The units for thresholds are in US Dollars. GNI calculations use the World Bank Atlas Method from 2018. Country income groups use classifications from the World Bank’s 2020 fiscal year

9 Prevalence of HPV (any serotype) Burden of Disease Estimated prevalence of HPV infection for any HPV serotypes. Based on two meta-analyses comprising 194 studies (n = 1,016,719 women) and 78 studies (n = 157, 879 women) between 1995 and 2016. Prevalence assessed by both Hybrid Capture 2 (HC2) techniques for HPV detection and polymerase chain reaction (PCR). Most studies sample women from the general population, including some with abnormal cytological findings. For each study, several details are shown: age range of the study population, number of women tested, number of women tested positive, source and citation of the study.

From two meta-analyses comprising 184 studies between 1995 and 2009. Type-specific HPV prevalence was expressed as the proportion of women positive for a given HPV type among all women tested for this type. Type-specific prevalence includes the presence of a given type either as a single type or combined with the presence of other concomitant types. Value is provided as a crude estimate and weighted by the number of women tested.

11 Net cost (US$) Predicted Impact of HPV Vaccination Model estimate. Estimated cost of vaccination per fully immunized girl, subtracting estimated treatment costs saved, and including any administration or delivery costs, in the scenario represented by the model. Values are computed by PRIME, a static model projecting vaccine impact, without requiring prior knowledge of screening outcomes. PRIME is simplified to ignore the magnitude of herd effects on unvaccinated females, suggesting an underestimation of vaccine impact. PRIME is not designed to evaluate options such as vaccinating males, vaccinating older females, catch-up campaigns or changes to cervical cancer screening. Estimations use a scenario in which 90% of females aged 9-14 years are vaccinated in 2030. Public access. Jit M, Brisson M.

26 HPV Vaccination Programme Coverage in Females HPV Vaccination Programme The percentage of the HPV Vaccination programme's target population that has received the first or last dose of HPV vaccine, per year. WHO recommends HPV vaccination for girls between 9 and 14 years of age. The exact ages targeted for HPV vaccines vary between countries with vaccination strategies differ from single age, school classes to multiple age-cohorts. As a result, defining meaningful and comparable coverage indicators for this vaccine is relatively complex. Therefore, the methodology uses two complementary indicators, one for programme performance in the last calendar year for all vaccination started in girls below 15 years of age and a complementary summary indicator on the resulting coverage in the cohort of 15-year old girls regardless of the year of vaccination. The latter indicator uses a cohort tracking approach: as numerator, it uses the cumulative number of doses ever received by a cohort of girls that are 15 years old in the reporting year, as per the data reported to WHO and UNICEF since 2011 (e.g., data for a cohort of girls turning 15 in 2018 would include in the numerator, doses administered to girls who were 10 years old in 2013, 11 in 2014, 12 in 2016, 13 in 2016, and 14 in 2017). Both indicators aim to measure coverage among all girls in target population regardless of strategy implemented. Public access.

27 HPV Vaccination Coverage in Females Aged 15 HPV Vaccination Programme The percentage of population turning 15 that received any time between age 9 to 14 at least one dose or the full recommended schedule of HPV vaccine, per year. These coverage figures are highly dependent on the consistency and quality of reporting from the previous 5 years, since it accumulates the number of doses administered to a specific birth cohort over time. WHO recommends HPV vaccination for girls between 9 and 14 years of age. The exact ages targeted for HPV vaccines vary between countries with vaccination strategies differ from single age, school classes to multiple age-cohorts. As a result, defining meaningful and comparable coverage indicators for this vaccine is relatively complex.
