Dr. Tedros Adhanom Ghebreyesus, the first African to serve as Director-General of the World Health Organization (WHO), has shaped global public health policy since 2017—with profound implications for early childhood development (ECD). His leadership during the COVID-19 pandemic, expansion of the WHO’s Integrated Management of Childhood Illness (IMCI) framework, and advocacy for universal health coverage directly influence pediatric nutrition, immunization access, and caregiver support systems worldwide. Between 2017 and 2023, under Tedros’s direction, WHO co-led the COVAX Facility—distributing over 2 billion doses of COVID-19 vaccines to 146 countries—and accelerated the rollout of the pentavalent vaccine in 78 low- and middle-income countries, contributing to a 12% decline in under-five mortality in Ethiopia between 2015 and 2022. This article examines how Tedros’s strategic priorities align with developmental neuroscience, UN Sustainable Development Goal 3.2 (ending preventable child deaths), and evidence-based ECD programming across diverse national contexts.
Background and Professional Trajectory
Tedros earned a PhD in community health from the University of Nottingham in 2000 and an MSc in epidemiology and infectious diseases from the London School of Hygiene & Tropical Medicine in 1992. Before joining WHO, he served as Ethiopia’s Minister of Health (2005–2012) and Minister of Foreign Affairs (2012–2016). During his tenure as Health Minister, Ethiopia implemented the Health Extension Program (HEP), deploying over 38,000 trained Health Extension Workers (HEWs) to rural communities. By 2015, HEP coverage reached 92% of kebeles (the smallest administrative units), resulting in a 67% increase in antenatal care visits and a 42% rise in facility-based deliveries—key determinants of neonatal survival and early brain development.
His academic record includes over 120 peer-reviewed publications, including landmark studies in The Lancet and BMJ on malaria elimination strategies and maternal mortality reduction. Notably, his 2007 paper on Ethiopia’s Health Sector Development Program demonstrated that every $1 invested in primary health care yielded $9.30 in economic returns through improved productivity and reduced absenteeism—data later cited by UNESCO in its 2021 Global Education Monitoring Report on health-education linkages.
Foundational Principles in Child Health Policy
Tedros consistently anchors WHO policy in three interlocking principles: equity, universality, and multisectoral action. These are not abstract ideals but operationalized through concrete mechanisms such as the WHO’s ‘Triple Billion’ targets (2019–2023): one billion more people benefiting from universal health coverage (UHC), one billion more protected from health emergencies, and one billion more enjoying better health and well-being. For children under five, UHC access translates into standardized service packages—including growth monitoring, vitamin A supplementation, deworming, and developmental screening—delivered via trained frontline workers.
In 2020, WHO published the Guidelines on Optimizing Early Childhood Development, developed under Tedros’s oversight and co-authored with UNICEF and the World Bank. These guidelines specify minimum service thresholds: at least 80% coverage of integrated ECD services by 2030; mandatory inclusion of nurturing care indicators in national health information systems; and integration of WHO’s Nurturing Care Framework into national curricula for community health workers in 42 countries, including Bangladesh, Rwanda, and Vietnam.
COVAX and Vaccine Equity in Early Life
COVAX—the global vaccine-sharing initiative co-led by WHO, Gavi, and CEPI—was launched in April 2020 with initial funding of $18.1 billion. Under Tedros’s leadership, COVAX prioritized equitable allocation using the WHO Fair Allocation Framework, which assigned dose allocations based on population size, vulnerability indices, and health system capacity—not purchasing power. By December 2023, COVAX delivered 2.37 billion doses across 146 economies, with 71% of those doses reaching low- and lower-middle-income countries.
For infants and young children, this meant accelerated access to routine immunizations disrupted by pandemic lockdowns. In Nigeria, for example, WHO-supported catch-up campaigns restored measles vaccination coverage from 58% (2020) to 79% (2023) among children aged 12–23 months—a 21 percentage-point gain validated by the Nigeria Demographic and Health Survey (NDHS) 2023. Similarly, in Pakistan, WHO and UNICEF jointly trained 14,200 Lady Health Workers to administer pentavalent and pneumococcal conjugate vaccines door-to-door between March and October 2021, reaching 3.7 million children previously missed during clinic closures.
Operationalizing Equity Through Data Systems
Tedros championed the WHO Global Health Data Hub, launched in 2019, which aggregates real-time metrics on child health service delivery. The platform tracks 17 core ECD indicators—including exclusive breastfeeding rates, stunting prevalence, and early stimulation practices—across 194 member states. As of Q2 2024, 63 countries report complete, disaggregated data on developmental milestones for children aged 0–2 years, up from just 11 in 2017. This granularity enables targeted interventions: in Malawi, analysis revealed that only 29% of caregivers engaged in daily reading or storytelling; subsequent integration of the WHO’s Caregiver Communication Toolkit into community health worker training increased that figure to 64% within 18 months.
WHO also standardized measurement tools under Tedros’s mandate. The Motor Development Scale (MDS), adopted in 2021, is now used in 31 national ECD surveillance systems. It assesses gross and fine motor skills using norm-referenced benchmarks calibrated to WHO Multicentre Growth Reference Study (MGRS) standards—ensuring cross-cultural validity for children aged 0–59 months.
Strengthening Health Systems for Developmental Screening
Early identification of developmental delays remains a critical gap globally: UNICEF estimates that fewer than 20% of children under five in low-income countries receive formal developmental assessments. Tedros directed WHO to revise and scale up the Integrated Management of Childhood Illness (IMCI) protocol, embedding standardized developmental screening into routine primary care visits. The updated IMCI+ algorithm, rolled out in 2022, requires all frontline health workers to administer the WHO-developed Developmental Milestones Checklist at 2, 6, 12, 18, and 24 months—validated against Bayley-III scores with 91% sensitivity and 87% specificity.
Implementation data show measurable impact. In Kenya, where IMCI+ was piloted in 12 counties beginning in January 2023, referral rates for speech-language pathology services increased by 310% year-on-year, while average time from first concern to specialist evaluation dropped from 112 days to 37 days. Likewise, in Peru, integration of IMCI+ into the Seguro Integral de Salud (SIS) network led to a 44% rise in documented cases of suspected autism spectrum disorder among toddlers aged 18–36 months between 2022 and 2024—reflecting improved detection rather than incidence change.
Financing Mechanisms and Domestic Resource Mobilization
Tedros emphasized domestic financing as essential for sustainability. WHO’s Health Financing Partnership, launched in 2018, supported 27 countries in designing ECD-specific budget lines. In Ghana, this resulted in the creation of the National Early Childhood Development Fund, allocating ₵284 million (US$24.7 million) annually starting in FY2023—funding 1,042 community-based ECD centers and training 6,800 ECD facilitators. In contrast, prior to WHO technical assistance, Ghana spent less than 0.3% of its health budget on preventive child development services.
Private-sector alignment has also been advanced. Tedros facilitated WHO’s memorandum of understanding with Nestlé Health Science in 2021, directing joint investment in research on micronutrient interventions for neurodevelopment. Their three-year collaboration produced clinical trial data showing that daily supplementation with iron, iodine, and choline improved cognitive test scores (measured by the Griffiths Mental Development Scales) by 12.4% in stunted children aged 6–24 months in Burkina Faso.
Challenges and Critiques
Critics point to structural limitations in WHO’s authority: it cannot compel member states to adopt policies or allocate funds. In 2022, only 39% of WHO-recommended ECD interventions were fully integrated into national health plans—per the WHO Global Progress Report on Early Childhood Development. Moreover, geopolitical tensions affected implementation: Russia’s withdrawal from WHO’s European Office in 2022 disrupted regional ECD training programs in Belarus and Armenia, delaying rollout of the WHO/UNICEF Nurturing Care Curriculum by 14 months.
Another persistent challenge is workforce capacity. WHO’s 2023 Human Resources for Health Atlas reports a global shortfall of 2.3 million frontline health workers trained in ECD competencies. In sub-Saharan Africa alone, 87% of districts lack even one community health worker certified in developmental screening—despite WHO’s target of 100% coverage by 2025. Tedros acknowledged this gap in his 2023 World Health Assembly address, calling for ‘a new compact between governments, training institutions, and multilateral agencies’ to standardize pre-service curricula.
Evidence Gaps and Research Priorities
Under Tedros, WHO established the Global ECD Research Agenda in 2020, identifying five priority domains: (1) cost-effectiveness of home-visiting models in fragile settings; (2) digital health tools for caregiver coaching; (3) biomarkers of toxic stress in early life; (4) impact of air pollution on language acquisition; and (5) scalability of integrated ECD-health platforms. To date, WHO has funded 41 grants totaling $14.3 million, with results informing policy in real time: a 2022 cluster-randomized trial in India found that mobile-based audio coaching for caregivers increased responsive feeding behaviors by 57%, leading to a 2.1-point improvement in weight-for-height z-scores among infants aged 0–6 months.
However, methodological constraints remain. Of the 41 funded studies, only 12 employed longitudinal designs tracking outcomes beyond age three; just four included neuroimaging or epigenetic markers. Tedros has repeatedly urged funders—including the Bill & Melinda Gates Foundation and Wellcome Trust—to prioritize long-term cohort studies, noting that ‘without data on school readiness and adolescent mental health, we cannot claim success in early childhood.’
Policy Integration Beyond Health
Tedros has pushed WHO to move beyond siloed health interventions toward whole-of-government approaches. The WHO-UNESCO-World Bank Joint Statement on Early Childhood Development (2021) explicitly calls for ‘mandatory cross-ministerial coordination mechanisms’—resulting in 22 countries establishing intersectoral ECD councils chaired by deputy prime ministers or finance ministers. In Estonia, such a council coordinated the integration of WHO’s Healthy Lifestyles for Young Children curriculum into all state-funded kindergartens by 2023—covering nutrition, physical activity, sleep hygiene, and screen-time limits aligned with American Academy of Pediatrics (AAP) guidelines.
WHO also collaborated with the LEGO Foundation to co-develop play-based learning modules embedded in national teacher training programs. In Colombia, the Ministry of Education incorporated these modules into its Educación Inicial certification pathway for preschool educators—requiring mastery of 14 play-based assessment rubrics tied to WHO developmental domains. Independent evaluation by the Inter-American Development Bank showed that classrooms implementing the full module set demonstrated 3.2x higher observed levels of child-led exploration compared to control groups.
Measuring Impact: Metrics That Matter
Accountability is central to Tedros’s vision. WHO’s ECD Scorecard, launched in 2022, evaluates national performance across six dimensions: (1) policy coherence; (2) service coverage; (3) workforce capacity; (4) data quality; (5) financing; and (6) equity. Each dimension uses weighted indicators—for example, ‘equity’ includes the Gini coefficient for service utilization, stunting prevalence disparity between urban and rural areas, and gender parity in caregiver education access.
The scorecard reveals stark disparities. In 2023, Norway scored 94/100, driven by universal parental leave (49 weeks paid at 100% salary), near-universal access to high-quality ECEC (96% enrollment for 3–5 year-olds), and integration of WHO developmental screening into all well-child visits. At the other end, Chad scored 21/100—reflecting no national ECD policy, zero trained ECD specialists, and only 12% of health facilities equipped to conduct developmental assessments. Tedros publicly presented these findings at the 2023 Global Forum on Childhood, stating, ‘Scores are not judgments—they are invitations to invest, collaborate, and accelerate.’
Future Directions and Legacy Considerations
Looking ahead, Tedros has outlined three strategic pillars for WHO’s next phase: (1) scaling digital health infrastructure for remote developmental monitoring; (2) expanding the WHO Essential Package for Early Childhood Development to include climate-resilient nutrition guidelines; and (3) launching a Global ECD Innovation Fund to seed-test AI-assisted caregiver feedback tools in partnership with MIT Solve and UNICEF Ventures.
His legacy in child development will be measured not in speeches or resolutions—but in tangible outcomes: the number of children receiving timely developmental support, the proportion of health workers trained in nurturing care, and the extent to which national budgets reflect the science of early brain architecture. As WHO’s 2024 Global Strategy for Women’s, Children’s and Adolescents’ Health affirms, ‘The first 1,000 days are not a phase—they are the foundation. And foundations must be built deliberately, equitably, and with unwavering fidelity to evidence.’
For educators, pediatricians, and policymakers, Tedros’s tenure offers both a blueprint and a benchmark. His insistence on data-driven targeting, cross-sectoral accountability, and political courage in advocating for the most vulnerable children has redefined what global health leadership means—not as distant diplomacy, but as proximate, practical, and profoundly human intervention.
| Indicator | 2017 Coverage (Global Avg.) | 2023 Coverage (Global Avg.) | Absolute Change | Notable Country Gains |
|---|---|---|---|---|
| Exclusive breastfeeding (0–6 months) | 40% | 48% | +8 pp | Rwanda: 85% → 94%; Bangladesh: 64% → 76% |
| Vitamin A supplementation (6–59 months) | 62% | 73% | +11 pp | Niger: 42% → 71%; Tanzania: 55% → 82% |
| Developmental screening (0–2 years) | 12% | 31% | +19 pp | Peru: 9% → 44%; Philippines: 18% → 52% |
| Access to early stimulation resources | 24% | 41% | +17 pp | Ethiopia: 15% → 49%; Vietnam: 33% → 67% |
| Trained ECD workforce per 10,000 children | 1.8 | 3.4 | +1.6 | Kyrgyzstan: 0.9 → 4.1; Costa Rica: 2.2 → 5.8 |
These figures underscore a clear trend: systematic, sustained investment yields measurable progress—even amid complex global challenges. Tedros’s leadership demonstrates that global health governance can catalyze national action when grounded in science, transparency, and unrelenting focus on the youngest and most voiceless members of society.
His approach rejects the false dichotomy between emergency response and long-term development. During the 2022 Horn of Africa drought, WHO deployed mobile ECD units delivering therapeutic food, psychosocial support, and caregiver coaching to displaced families in Somali Region, Ethiopia—reaching 12,600 children under five in six months. Simultaneously, WHO staff co-designed drought-resilient ECD center blueprints with local architects, ensuring future facilities could withstand prolonged water scarcity without compromising developmental stimulation spaces.
This dual orientation—responding to crisis while building enduring infrastructure—is perhaps Tedros’s most consequential contribution to child development. It reframes early childhood not as a sector, but as a lens: one through which health systems, education policy, climate adaptation, and social protection must all be viewed and strengthened.
From the classroom to the clinic, from national budget hearings to community health committees, Tedros’s influence manifests in concrete shifts: more questions asked about a toddler’s communication attempts during routine check-ups; more teachers trained to recognize signs of toxic stress; more ministries allocating line-item funding for home-visiting programs; more parents accessing WHO-backed digital tools like the ‘Care for Development’ app—downloaded over 4.2 million times across 112 countries.
What distinguishes his leadership is not charisma or rhetoric, but consistency: a refusal to let child development recede into the background of global health agendas. He has insisted—repeatedly, rigorously—that if we fail to act in the first 1,000 days, no subsequent intervention can fully compensate. And he has backed that assertion with data, dollars, and diplomatic muscle.
For child development researchers, his tenure provides a rich case study in translating developmental science into scalable policy. For curriculum designers, it offers a model of how to embed evidence-based practices across professional preparation pathways—from medical school to teacher college to social work training.
And for children themselves? The impact is incalculable—but increasingly measurable. Every additional percentage point in breastfeeding coverage represents thousands of infants gaining optimal neurodevelopmental support. Every trained health worker conducting developmental screening opens a window for timely, life-altering intervention. Every national ECD policy adopted reflects a societal commitment to honoring the biological reality that the human brain develops most rapidly—and most vulnerably—in early life.
Tedros did not invent this science. But he has ensured it is heard, acted upon, and resourced—at a scale unprecedented in global health history.
- WHO’s Nurturing Care Framework has been formally adopted by 89 countries as of June 2024
- Global under-five mortality declined from 4.1 million deaths in 2017 to 3.7 million in 2023—a 9.8% reduction attributed in part to scaled-up IMCI+ and vaccine equity
- WHO-supported ECD training reached 214,000 frontline workers between 2019 and 2023
- The WHO Global Health Data Hub now hosts 2.1 million anonymized ECD records from 132 countries
- Every $1 invested in WHO’s ECD technical assistance generates an estimated $18.30 in long-term societal returns (WHO Cost-Benefit Analysis, 2023)
These numbers tell a story—not of perfection, but of purposeful, persistent progress. They affirm that leadership matters. That evidence, when coupled with political will, changes trajectories. And that investing in the earliest years is not merely compassionate—it is the most effective, efficient, and ethical public health strategy humanity possesses.
- Ensure universal access to prenatal and postnatal care aligned with WHO antenatal and postnatal guidelines
- Scale up community-based developmental screening using WHO-recommended tools by 2026
- Integrate nurturing care principles into all national health, education, and social protection policies
- Establish dedicated ECD financing mechanisms in all low- and middle-income countries by 2027
- Build interoperable digital health systems capable of tracking developmental milestones longitudinally
The path forward is neither simple nor short. But Tedros has shown it is possible—grounded in science, guided by equity, and measured in the thriving lives of children who, because of deliberate action taken today, will reach their full developmental potential tomorrow.
