Concordance of self-assessment and self-reporting of National Immunization Technical Advisory Group process indicators in the Eastern Mediterranean Region.

ABSTRACTWe describe the existence and functionality of National Immunisation Technical Advisory Groups (NITAGs) in Africa between 2010 and 2016, using data from the WHO-UNICEF Joint Reporting Form. The number of African countries with NITAGs increased from 15 (28%) in 2010 to 26 (48%) in 2016. Countries with a functioning NITAG increased from 5(9%) in 2010 to 16 (30%) in 2016. In 2016, 13 of the 27 (48%) low-income African countries reported having a NITAG; seven (54%) of them functional. Thirteen of the 26 (50%) middle-income countries reported having a NITAG; nine (69%) of them functional. In 2016, six of the seven African countries (86%) in the WHO Eastern Mediterranean Region had a NITAG, with three (50%) functional. In the WHO African Region, 20 of the 47 countries (43%) had NITAGs; 13 (65%) of them functional. Substantial investments should be made to ensure that every African country has a functional NITAG.

To document the first application of the WHO New Vaccine Introduction Prioritization and Sequencing Toolkit (NVI-PST) in the WHO Eastern Mediterranean Region and to describe how Iran's National Immunization Technical Advisory Group (NITAG) adapted and implemented the framework to develop a prioritised roadmap for vaccine introduction during 2025-2030. Policy implementation case study applying a structured multicriteria decision analysis-informed prioritisation framework through a three-phase process including framework adaptation, evidence synthesis, ordinal ranking of candidate vaccines, weighted aggregation and development of sequencing scenarios. National immunisation governance process in Iran, coordinated by the Ministry of Health and Medical Education and Iran's NITAG, with technical support from the WHO Country Office. Core and non-core members of Iran's NITAG and key immunisation stakeholders involved in the deliberative prioritisation process. Human papillomavirus (HPV) vaccine ranked highest in both importance and feasibility, followed by pneumococcal conjugate vaccine (PCV) for high-risk adults and seasonal influenza vaccine for high-risk groups. Two sequencing scenarios were proposed: both placed HPV first, with either PCV or influenza third after the already-approved hexavalent vaccine. Respiratory syncytial virus (RSV) and varicella vaccines were classified as low priority for the 5-year horizon. The toolkit enabled structured multistakeholder deliberation, improved the transparency and reproducibility of prioritisation, and supported systematic integration of epidemiological, economic and programme evidence. The main implementation challenges arose from national evidence constraints, particularly gaps in adult RSV and pneumococcal disease burden, limited locally generated cost-effectiveness analyses and uncertainty in long-term budget impact estimation under macroeconomic instability, rather than from limitations of the toolkit itself. The NVI-PST proved feasible under national leadership and generated credible, consensus-based recommendations aligned with Iran's public health priorities and programme constraints. Minor refinements (streamlined evidence compendium, simpler weighting, stronger secretariat support) would make the toolkit lighter and more sustainable, especially for resource-constrained settings. This Iranian experience provides a replicable model for structured multi-vaccine prioritisation in the Eastern Mediterranean Region and beyond.

National Immunization Technical Advisory Groups (NITAGs) are independent bodies that help improve national immunization programmes in decision making on immunization policy. The new NITAG Maturity Assessment Tool (NMAT) provided an opportunity to conduct a region-wide assessment to improve NITAG capacity and foster institutional growth. We share experience of the Eastern Mediterranean Region (EMR) of the World Health Organization (WHO) in using NMAT and the use of findings to develop improvement plans. NITAG chairs and secretariats from 22 EMR countries attended a virtual NMAT training in 2023. They self-assessed their NITAGs using the tool and developed improvement plans. An algorithm used the data to determine maturity levels for seven indicators. We consolidated results for the region by income groups. Of 22 countries (or NITAGs), 20 (91%) submitted NITAG assessment findings and 19 an improvement plan. The proportion of criteria met per indicator varied from 36% for independence and non-bias to 74% for establishment and composition. Maturity level varied by indicator. Of 20 NITAGs, less than half had an intermediate or higher-level maturity for the indicators of independence and non-bias 1 (5%), operations 3 (15%), making recommendations 4 (20%), stakeholder recognition 6 (30%), and resources and secretariat support 7 (35%). Meanwhile 11 (55%) NITAGs had an intermediate or higher maturity level for the indicators of establishment and composition and for integration into policy making process. Participants described NMAT as a concise, useful, user-friendly tool. NMAT is a practical tool that can be used by NITAGs to provide insights and strategic direction for individual countries and regionally. Prevention and management of conflict of interest is the domain that requires the most improvement in EMR. Planned activities should be implemented, monitored and a follow up assessment conducted in 2025.

In the Eastern Mediterranean Region (EMR) of the World Health Organization (WHO), little is known on National Immunization Technical Advisory Groups’ (NITAGs) outputs, including recommendations and their outcomes. We abstracted information from the WHO/UNICEF joint reporting forms and extracted implemented immunization policy decisions from the WHO immunization portal. We describe trends in establishments and functionality of NITAGs and immunization policies implemented in EMR from 2010 to 2021. In 2013, all 22 EMR countries had a NITAG, although only 20 remained active in 2021. The number of countries meeting six NITAG process indicators increased from 7 in 2010, to 14 in 2019, then reduced to 12 in 2021. In 2021, the proportion of countries with a functional NITAG decreased with income level, from 83% in high-income countries, to 55% in middle-income countries and 20% in low-income countries. From 2010 to 2021, there were 103 new vaccine introductions, 31 vaccine switches, and 28 schedule changes implemented across all 22 countries, irrespective of income groups. While NITAGs are established and making recommendations in countries, their functionality decreases with income level. Governments should continue to invest in NITAGs, including on strengthening processes and ensuring that recommendations made are based on evidence to decision frameworks.

The role of National Immunization Technical Advisory Groups (NITAG) in strengthening health system governance: Lessons from three middle-income countries—Argentina, Jordan, and South Africa (2017–2018)

A National Immunization Technical Advisory Group (NITAG) provides independent guidance to Ministries of Health (MoH) and policymakers, enabling them to make informed decisions on national immunization policies and practices. As of 2022, 50 of the 53 countries in the World Health Organization (WHO) European Region (the Region) had established a NITAG, with 58% of all NITAGs and 66% of those in middle-income countries (MICs) in the Region meeting all six WHO process indicators of NITAG functionality. However, many newly established NITAGs in MICs in the Region experience challenges in terms of their functioning, structure, and outputs. To address these challenges and achieve the goal of evidence-informed decision making on immunizations, the WHO Regional Office for Europe and the Robert Koch Institute (RKI) implemented a project to strengthen the functioning of MIC NITAGs of the Region through comprehensive evaluations of nine NITAGs and development and implementation of improvement plans. All evaluated NITAGs are formally established and complete the most important aspects of NITAG functioning. The main challenge for all NITAGs is the lack of a well-staffed Secretariat to establish annual workplans and develop NITAG recommendations following a standardized process. The evaluation identified NITAGs' strengths and challenges. Some challenges have been addressed through improvement plan implementation. WHO and RKI will continue to evaluate NITAGs and support development and implementation of improvement plans. WHO and NITAG partners will continue to provide training on the standardized recommendation-making process and advocate increased MoH support to NITAGs, including dedicated Secretariat staff.

The Global Vaccine Action Plan proposes that every country establish or have access to a National Immunization Technical Advisory Group (NITAG) by 2020. The NITAG role is to produce evidence-informed recommendations that incorporate local context, to guide national immunization policies and practice. This study aimed to explore the value and effectiveness of NITAGs in low- and middle-income countries (LMICs), identifying areas in which NITAGs may require further support to improve their functionality and potential barriers to global investment. A multi-methods study design was used, comprising 134 semi-structured interviews and 82 literature review sources that included 38 countries. Interviews were conducted with 53 global/regional and 81 country-level participants able to provide insight into NITAG effectiveness, including NITAG members, national immunization programme staff, and global agency representatives (e.g. the World Health Organisation, the Bill and Melinda Gates Foundation, Gavi the Vaccine Alliance). The review, including published and unpublished sources on NITAGs in LMICs, was conducted to supplement and corroborate interview findings. Data were analysed thematically. NITAGs were described as valuable in promoting evidence-informed vaccination decision-making, with NITAG involvement enhancing national immunization programme strength and sustainability. Challenges to NITAG effectiveness included: (1) unreliable funding; (2) insufficient diversity of member expertise; (3) inadequate conflicts of interest management procedures; (4) insufficient capacity to access and use evidence; (5) lack of transparency; and (6) limited integration with national decision-making processes that reduced the recognition and incorporation of NITAG recommendations. LMIC NITAGs have developed significantly in the past decade. Well-functioning NITAGs were trusted national resources that enhanced country ownership of immunization provision. However, many LMIC NITAGs require additional technical and funding support to strengthen quality and effectiveness, while maintaining impartiality and ensuring sufficient integration with national decision-making processes. Barriers to sustainable global support need to be addressed for LMIC NITAGs to both continue and develop further.

IntroductionImproving evidence informed decision-making in immunisation is a global health priority and many low and middle-income countries have established National Immunisation Technical Advisory Groups (NITAGs) as independent technical advisory bodies for this purpose. NITAG development and strengthening has received financial and technical support over the past decade, but relatively little evaluation. This study examined NITAGs in six low and middle-income countries (i.e. Armenia, Ghana, Indonesia, Nigeria, Senegal, Uganda), to examine functionality, quality of recommendation development, and integration with national decision-making bodies and processes. MethodsA mixed-method case-series design, used semi-structured interviews, NITAG meeting observations, and document review. Data were analysed thematically. ResultsFive NITAGs had been legally established with terms of reference and appeared well functioning, with Ghana’s in development. All NITAGs had standard operating procedures and nomination procedures to ensure a range of expertise, generally comprising 10–15 core, 1–5 secretariat, and several ex-officio members. Aside from economics, NITAGs reported a wide range of member expertise. Newer NITAGs had particular concerns about funding. Four used formal conflict of interest procedures, although some commented that implications were not always understood. NITAGs valued local data, and limited evidence suggested NITAG presence might reinforce data production through surveillance and local research studies. All observed meetings demonstrated due process and evidence-based decision-making processes were generally followed, with a critical role played by working-group data syntheses and assessments. NITAGs were seen as well integrated with ministry of health (MoH) decision-making and MoH interviewees were positive about NITAG contributions, indicating NITAGs had an important role. Collaboration with other bodies was more limited, but mitigated by NITAG members’ cross-membership in other bodies. ConclusionsNITAGs have an important and valued role within national immunisation decision-making. However, their position remains insecure, with the need for sustainable technical and financial support.

The protozoan parasite Toxoplasma gondii may cause serious illness in the immunocompromised. The Toxoplasma gondii seropositive prevalence in pregnant women in WHO Eastern Mediterranean Region countries is inconsistent in the literature and it is associated with outcomes that have not be fully elucidated, hence the need for a better understanding of the pooled seroprevalence and associated maternal and fetal outcomes. The objective was to conduct a systematic literature review and determine the pooled prevalence of WHO Eastern Mediterranean Regional countries' pregnant women's seroprevalence of Toxoplasma gondii and the maternal-fetal outcomes. This quantitative study examined WHO Eastern Mediterranean countries' maternal-fetal outcomes and Toxoplasma gondii prevalence in pregnant women. The targeted population was pregnant women, while the primary outcome was seropositivity of Toxoplasma gondii, while other outcomes such as maternal and fetal associations and risk factors were determined PubMed, SCOPUS, MEDLINE, and Index Medicus for the Eastern Mediterranean Region (IMEMR) databases were searched up until 30 January 2023. The search terms used were "Toxoplasma gondii" OR "Toxoplasma infection" AND "Pregnant woman" or pregnan* OR Antenatal OR Prenatal OR Gravidity OR Parturition OR Maternal AND WHO Eastern Mediterranean Region). OpenMeta-Analyst and Jamovi were used to analyze the generated data. In total, 95 of 2947 articles meeting the inclusion criteria examined Toxoplasma gondii prevalence in pregnant women from WHO Eastern Mediterranean countries. The pooled prevalence of Toxoplasma gondii in pregnant women was 36.5% (95%CI: 32.6-40.4) with a median value of 35.64%, range values of 1.38-75.30%, with 99.61% heterogeneity. The pooled seroprevalence of IgG of Toxoplasma gondii was 33.5% (95%CI: 29.8-37.2) with a median value of 33.51%, and a range values of 1.38-69.92%; the pooled seroprevalence of IgM was 3.6% (95%CI: 3.1-4.1)) with a median value of 3.62 and range values of 0.20-17.47%, while cases of pooled seroprevalence of both IgG and IgM positivity was 3.0% (95%CI: 1.9-4.4) with a median value of 2.05 and a range values of 0.05-16.62%. Of the Toxoplasma gondii seropositive women, 1281/3389 (34.8%) 174/1765 (32.9%), 1311/3101 (43.7%), and 715/1683 (40.8%) of them had contact with cats, drank unprocessed milk, ate raw or undercooked meat and ate unwashed raw vegetables, respectively. The maternal-fetal outcomes associated with Toxoplasma gondii seropositivity were a history of abortions, miscarriage, stillbirth, intrauterine fetal death, and premature birth, which were found in 868/2990 (32.5%), 112/300 (36.1%), 111/375 (25.7%), 3/157 (1.9%) and 96/362 (20.1%) of women who tested positive for Toxoplasma gondii antibodies. The study found a high proportion of Toxoplasma gondii seroprevalence in pregnant women in the WHO Eastern Mediterranean Region, which may be linked to poor outcomes for mothers and their babies. Thus, pregnant women require monitoring and comprehensive prevention strategies for Toxoplasma gondii infection.

Progress in the establishment and strengthening of national immunization technical advisory groups: Analysis from the 2013 WHO/UNICEF joint reporting form, data for 2012

Background.National Immunization Technical Advisory Groups (NITAGs) are established by national authorities to provide them with independent, bias-free, objective, and evidence-based advice on vaccines and immunization challenges. As of December 2015, 125 countries have reported having set up an NITAG. The Health Policy and Institutional Development Center at the Agence de Médecine Préventive, a World Health Organization (WHO) Collaborative Center for evidence-informed immunization, through its Supporting Independent Immunization and Vaccine Advisory Committees (SIVAC) Initiative project, provides assistance to low- and middle-income countries in the establishment and strengthening of their NITAGs. The Indonesian NITAG (ITAGI) was formed in December 2006 and Uganda’s (UNITAG) was formed in November 2014. Both Uganda and Indonesia have introduced inactivated polio vaccine (IPV) as part of the Global Polio Eradication and Endgame Strategic Plan (the Endgame plan). The authors reflect on the process and the role played by NITAGs in the introduction of IPV in the routine immunization program and the lessons learned.Methods.This commentary is a reflection of the authors’ experience on NITAG’s role as observed in 2 particular local settings and applied to a global public health issue, the polio eradication Endgame plan. The reflection is backed up by the relevant (policy and technical) documents on polio eradication, along with minutes and reports from countries’ ministries of health, immunization programs, WHO, and NITAGs.Results.NITAGs are valuable tools for ministries of health to ensure sustainable, evidence-informed immunization policies that are trusted and accepted by their communities. Early engagement with NITAGs also ensures that the adoption of strategies addressing global public health threats at the country level reinforces the national immunization programs. On the other end, when NITAGs are proactive and forward-thinking, they can contribute to a smooth and effective introduction of the above-mentioned strategies. Time and resources are key factors to ensure optimal performance of NITAGs.

Background National Immunisation Technical Advisory Groups (NITAGs) play a critical role in evidence-informed decision-making (EIDM) for immunisation programs. However, African NITAGs face challenges, including limited technical capacity, inadequate resources, and insufficient vaccinology training tailored to their needs. To address these gaps, the NITAG Support Hub (NISH) launched the Annual Vaccinology Course for NITAGs (AVCN) in 2022. Methods The AVCN is a five-day residential course designed to enhance the technical and operational capacity of NITAGs. It combines didactic lectures, interactive sessions, and case studies to provide practical knowledge in vaccinology, health economics, and EIDM. Participants are selected in collaboration with the World Health Organisation (WHO), ensuring representation from diverse linguistic and geographic regions. Results Over three years, the AVCN trained 123 NITAG members from 19 African countries, with representation from WHO African and Eastern Mediterranean regions. Feedback collected through daily evaluations and After-Action Reviews highlights the course's relevance, comprehensive content, and practical utility. Participants emphasised the value of group training, interactive methodologies, and opportunities for experience sharing. Key improvements included increased time for discussions and expanded focus on design thinking and health systems. Conclusion The AVCN is a pioneering initiative that addresses critical gaps in NITAG capacity building in Africa. Its tailored design and iterative improvements have established it as a model for NITAG vaccinology training globally. By fostering collaboration and building technical capacity, the AVCN contributes significantly to strengthening immunisation systems in Africa and beyond.
