For every child, the right to vaccine

The purpose of the assessment is to conduct a critical review of the current methodology used to calculate vaccination coverage in North Macedonia. This review will be informed by the latest scientific evidence, as well as examples and experience from other countries. The assessment will analyse the existing data sources for coverage calculation, identify gaps and limitations in the current approach and propose revised data sources, methodologies and templates to enhance the accuracy and reliability of vaccination coverage data. For this purpose, UNICEF North Macedonia seeks to engage a national expert with proven expertise in immunization processes and vaccination coverage calculation. The selected consultant shall work in close collaboration with the UNICEF Health and Nutrition Officer and National Immunization Expert Group nominated by the Minister of Health, as outlined in the scope of work section.

Background information:

Immunization coverage is a critical metric for monitoring and evaluating the performance of immunization programs. It helps determine whether coverage targets are being met and identify communities and/or subpopulations that may require additional support through supplemental immunization activities. High-quality coverage data is essential for informed decision-making at the local, regional and national levels. In all United Nations member states, reliable coverage data is also vital for strengthening surveillance systems and supporting the documentation and certification of disease elimination efforts, such as for measles, rubella and polio.

Accurate coverage calculations, typically rely on the number of vaccine doses administered divided by the target population. This calculation depends on robust data collection. Weak or incomplete data can result in misleading coverage figures, potentially undermining public health efforts and increasing the risk of disease resurgence. Coverage rates also serve as a key indicator of how effectively a population is protected against vaccine-preventable diseases. Immunization coverage calculations are crucial in North Macedonia for the same reasons it matters globally: to track progress, prevent outbreaks and monitor potential setbacks.

The country aligns with the WHO/UNICEF Estimates of National Immunization Coverage (WUENIC) methodology for reporting and estimating coverage.

The coverage formula used is: Coverage (%) = (Number of individuals vaccinated / Target population) × 100

- The numerator includes individuals in the target population (e.g., children under 5) who have received the recommended vaccine doses (e.g., MCV1 for measles, DTP3 for diphtheria-tetanus-pertussis)
- The denominator is the estimated target population, typically derived from census data, birth registries, or health system records.

Data sources include administrative data from health facilities and vaccination records reported to the Ministry of Health; household survey data (e.g., Multiple Indicator Cluster Surveys by UNICEF) and WHO/UNICEF national reports, which may incorporate adjustments based on expert input.

Several challenges continue to affect the accuracy and reliability of immunization coverage calculations in North Macedonia:

• Incomplete or inaccurate data. Administrative data from health facilities can be incomplete due to under-reporting or manual record-keeping errors, especially in rural or underserved areas such as Roma communities. These issues can distort both the numerator (number of vaccinated individuals) and the denominator (target population), leading to inaccurate coverage estimates. Although North Macedonia has introduced a national electronic immunization database to improve data quality, gaps persist in certain regions.

• Disparities across regions and communities. Vaccination coverage varies significantly across municipalities and ethnic groups. Roma communities and rural areas often have lower vaccination rates due to limited access to healthcare, cultural barriers or socioeconomic factors. Aggregated national data may mask these local disparities, making it difficult to identify and address specific gaps. Additionally, outdated census data and unregistered births complicate the estimation of accurate denominators for minority or mobile populations.

• Limited survey data. North Macedonia relies on administrative data supplemented by household surveys (e.g., UNICEF’s Multiple Indicator Cluster Surveys held every 4-5 years, the latest being in 2018). However, surveys are resource-intensive and not conducted annually, limiting timely validation of coverage estimates. Without frequent household surveys, coverage may be overestimated due to unrecorded dropouts or refusals. In addition, WHO/UNICEF adjustments (via WUENIC methodology) may not fully capture local nuances without recent survey data.

• Capacity and training gaps. Despite WHO-led training of over 400 health workers in 2023-2024 to improve immunization delivery and reporting, some areas still lack adequately trained personnel for accurate data collection. Inconsistent reporting practices across health facilities further undermine data reliability. Addressing these challenges requires sustained investment in workforce training and digital infrastructure, which is still in the process of scaling up.

How can you make a difference? 

Scope of Work:

To implement this task, UNICEF North Macedonia seeks to engage a national consultant who will work in close collaboration with Health and Nutrition Officer. The consultant will be responsible for the following tasks:

1. Comprehensive review of the current methodology. The consultant should conduct a thorough assessment of the existing methodology used to calculate vaccine coverage in North Macedonia. This includes: evaluation of data sources (e.g., administrative data, electronic immunization systems), data collection processes, and analytical methods. The review should identify strengths, weaknesses, and gaps, such as incomplete reporting, underestimation of coverage due to unregistered populations (e.g., Roma communities), and inconsistencies in data between urban and rural areas.

2. Propose a revised methodology. The consultant should develop a new or update the current methodology for calculating vaccine coverage, drawing on global best practices (e.g., WHO’s Guide for Standardization of Economic Evaluations of Immunization Programmes or Gavi’s monitoring approaches to immunization). The proposal should include detailed guidelines for data collection, standardized data sources, sampling methods, and robust statistical approaches to ensure representativeness and accuracy. The methodology should be adapted to local context (e.g., addressing vaccine hesitancy, accounting for disruptions like COVID-19 pandemic). In addition, the methodology should be cost-effective and feasible in low-resource settings and aligned with the new National Immunization Strategy 2030 (under development) to support its acceptance and data collection efforts.

3. Development of data collection and analysis tools. The consultant should design and adapt tools (e.g., templates or spreadsheets) for data collection and analysis, ensuring compatibility with North Macedonia’s health infrastructure. It should include protocols for data validation and quality assurance, such as cross-referencing administrative data with survey-based estimates or using mobility data to track coverage in transient populations.

4. Stakeholder engagement and training plan. The proposed methodology should undergo through broad consultations with key stakeholders (e.g., Ministry of Health, Institute of Public Health, UNICEF North Macedonia, WHO representatives) to validate the revised methodology and ensure alignment with national health priorities. Based on these consultations, the consultant should develop a training manual or workshopcurriculum for health workers and data managers on the implementation of the revised methodology, including guidance on using the new tools and addressing data gaps in underserved communities.

5. Policy brief for decision-makers. The consultant should prepare a concise policy brief summarizing the revised methodology and, its benefits, its alignment with global standards and recommendations for policymakers on resource allocation, addressing urban-rural disparities, ensuring financial sustainability and equitable access. The deliverables should ensure that the revised methodology is evidence-based, locally relevant, and aligned with the best global practices. Ultimately, the goal is to enhance vaccine coverage monitoring and improve public health outcomes in North Macedonia.
