Global Health’s Defining Test

A Year That Redefined Global Health Priorities

Global Health’s Defining Test out as a defining moment for global health. It was a year marked by scientific breakthroughs, humanitarian emergencies, and renewed debates over international cooperation. As governments, scientists, and health workers navigated complex challenges, one lesson became unmistakably clear: global health cannot be protected in isolation.

Multilateral cooperation, evidence-based science, and shared responsibility were repeatedly tested. From pandemic preparedness to disease elimination and digital health innovation, progress depended on countries choosing collaboration over fragmentation. As the world enters 2026, these lessons are more relevant than ever.

Pandemic Preparedness: A Historic Turning Point

One of the most significant global health achievements of 2025 was the adoption of the WHO Pandemic Agreement by Member States. This landmark decision aims to ensure the world is better prepared for future pandemics through stronger coordination, transparency, and equity.

At the same time, amendments to the International Health Regulations (IHR) came into force. These included the introduction of a new “pandemic emergency” alert level, designed to trigger faster international responses and data sharing during global health threats.

Equally important was the decision by governments to increase funding for the WHO’s core budget, reinforcing trust in multilateral institutions at a time of growing geopolitical strain.

Initiative	Purpose	Global Impact
WHO Pandemic Agreement	Prevent and manage future pandemics	Stronger global coordination
IHR Amendments	Faster emergency alerts	Improved early response
Increased WHO Funding	Sustainable health financing	Greater institutional stability

Pathogen Sharing and Equitable Access

Negotiations continued throughout 2025 on the Pathogen Access and Benefit Sharing (PABS) system, a core pillar of the Pandemic Agreement. The framework seeks to guarantee rapid sharing of pathogen samples and genetic data, while ensuring fair access to vaccines, diagnostics, and treatments.

If finalized by mid-2026, the agreement is expected to enter into force as international law—marking a shift toward more equitable global health security.

Science, Vaccines, and Public Trust

Science remained at the heart of global health progress. In 2025, the WHO reaffirmed the safety and effectiveness of vaccines, while issuing guidance on new medical innovations, including:

Injectable lenacapavir for HIV prevention
GLP-1 therapies for obesity management

Immunisation continued to prove its unmatched value as a public health intervention, saving millions of lives each year.

Vaccine Impact Highlights

Indicator	Progress Achieved
Global measles deaths	Down 88% since 2000
Malaria vaccine rollout	Active in 24 African countries
HPV vaccinations	86 million girls protected
Under-five mortality	Reduced by over 50% in 25 years

Vaccines are not optional add-ons—they are essential health services and a cornerstone of universal health coverage.

Major Victories in Disease Elimination

Several countries reached historic milestones in disease elimination during 2025:

Maldives achieved triple elimination of mother-to-child transmission of HIV, syphilis, and hepatitis B
Brazil eliminated mother-to-child transmission of HIV
Niger became Africa’s first country to eliminate river blindness
Georgia, Suriname, and Timor-Leste were certified malaria-free

These achievements reflect years of sustained public health investment and community engagement.

Addressing Obesity as a Global Health Crisis

Obesity emerged as one of the fastest-growing health challenges worldwide, affecting more than one billion people. Recognising its complexity, the WHO released its first guideline on GLP-1 therapies for obesity, emphasising that medication must be part of a comprehensive, lifelong care approach.

While pharmaceutical advances offer new hope, experts stress that prevention, nutrition, physical activity, and social support remain equally vital.

Digital Health and Innovation

Rapid advances in artificial intelligence, genomics, robotics, and data science are transforming healthcare delivery. In 2025, digital tools such as self-monitoring blood pressure programs for pregnant women demonstrated how innovation can strengthen primary healthcare, particularly in rural and underserved areas.

The WHO plans to expand support for countries adopting scalable digital health solutions in 2026.

Universal Health Coverage: Progress and Gaps

Despite improvements since 2000, progress toward universal health coverage (UHC) has slowed. Today:

4.6 billion people lack access to essential health services
Over 25% of the global population faces financial hardship due to healthcare costs

These gaps are not inevitable. With sustained political commitment and fair financing, progress remains achievable.

Health in Humanitarian Crises

In 2025, the WHO supported 48 health emergencies across 79 countries, reaching more than 30 million people. Responses ranged from cholera vaccination campaigns in Sudan to medical evacuations from Gaza.

However, escalating conflicts and attacks on healthcare facilities continue to violate international law. Healthcare workers and patients must never be targets.

Looking Ahead: Health as a Shared Responsibility

The events of 2025 highlighted both the resilience of the global health community and the risks posed by inequality, conflict, and funding cuts. The adoption of the Pandemic Agreement and advances in disease elimination prove that progress is possible when nations work together.

As the world moves into 2026, prioritising collective health is not just a moral obligation—it is a strategic necessity. By strengthening cooperation, investing in science, and protecting the most vulnerable, the global community can move closer to the WHO’s founding vision: health as a fundamental right for all, not a privilege for a few.
