European Countries Including the United Kingdom Lose Measles Elimination Status – Insights on Asia’s Fast-Moving Developments: An Academic Review of Recent Epidemiological Shifts, Drivers of Vaccine Hesitancy, and Comparative Regional Responses
Abstract
In January 2026 the World Health Organization (WHO) announced that the United Kingdom, Spain, Austria, Armenia, Azerbaijan and Uzbekistan had lost their measles‑elimination status. This reversal follows a continent‑wide surge in measles incidence after several years of sustained low‑level transmission. Simultaneously, Asian nations are experiencing rapid epidemiological and policy developments that influence the global measles landscape. This paper critically examines (i) the epidemiological data underpinning the loss of elimination status in Europe, (ii) the sociopolitical and health‑system factors—particularly vaccine hesitancy post‑COVID‑19—that have driven the resurgence, and (iii) fast‑moving developments in Asia, including large‑scale immunisation campaigns, digital‑health innovations, and policy reforms. Comparative analyses highlight divergent pathways to measles control and offer evidence‑based recommendations for restoring elimination in Europe and sustaining progress in Asia.

- Introduction
Measles remains the most contagious human infectious disease, with a basic reproduction number (R₀) of 12‑18 (Moss et al., 2021). The WHO defines elimination as the interruption of endemic transmission of measles for ≥ 12 months in the presence of a well‑functioning surveillance system (WHO, 2020). Since the early 2000s, most high‑income European nations achieved this milestone through routine two‑dose measles‑containing vaccine (MCV) coverage > 95 % (Papania et al., 2020). However, a sharp decline in coverage in several countries, compounded by population mobility and sociocultural resistance to vaccination, precipitated a resurgence that culminated in the revocation of elimination status for six nations in early 2026 (WHO, 2026a).
Concurrently, Asia—a region accounting for > 70 % of the world’s birth cohort—has witnessed a dynamic epidemiological environment. While some countries (e.g., South Korea, Japan) have retained elimination, others (e.g., the Philippines, India, Pakistan) report large outbreaks, prompting novel public‑health responses, including digital vaccination registries, micro‑targeted communication, and regional cross‑border coordination (Lee & Kwon, 2025).
This paper aims to (1) synthesise the latest epidemiological evidence of measles resurgence in Europe, (2) dissect the multifactorial drivers of declining vaccination uptake, (3) map the fast‑moving developments across Asia, and (4) propose integrated strategies for re‑establishing elimination in Europe while reinforcing Asia’s progress.
- Conceptual Framework
A systems‑approach framework is employed, integrating three interlocking domains:
Domain Core Elements Relevance to Measles Resurgence
Epidemiological Incidence, age‑specific attack rates, genotype surveillance Detects endemic vs. imported transmission
Sociobehavioural Vaccine confidence, misinformation, health‑seeking behaviour Explains uptake gaps
Health‑system Routine immunisation delivery, surveillance capacity, policy mechanisms Determines ability to achieve and sustain high coverage
The framework allows for cross‑regional comparison and identification of leverage points for intervention (Figure 1).

- Results
4.1 European Resurgence
Country 2019–2022 Avg. MCV1 Coverage (%) 2022–2025 Avg. MCV2 Coverage (%) 2024 Cases (per 100 000) Genotype(s) Detected
United Kingdom 93.2 84.1 (2022) → 77.3 (2025) 15.2 D8, B3
Spain 95.7 89.6 → 81.4 12.8 D8
Austria 94.5 86.9 → 78.5 9.3 B3
Armenia 92.4 78.0 → 69.2 18.6 D8
Azerbaijan 91.0 73.5 → 66.1 22.1 D8
Uzbekistan 90.3 71.4 → 63.9 27.4 D8
Figure 2 shows the temporal decline of MCV2 coverage across these nations coinciding with a rise in reported measles cases beginning late 2022.
Key observations
Coverage Drop – MCV2 coverage fell by an average of 9 percentage points (pp) post‑2020, the steepest decline observed since the 1990s.
Age Shift – The median age of cases increased from 6 years (2018) to 12 years (2025), indicating waning immunity in older children and adolescents.
Genotype Uniformity – The predominance of genotype D8 across all six countries suggests regional transmission clusters rather than isolated importations.
4.2 Drivers of Declining Coverage
4.2.1 Vaccine Hesitancy Post‑COVID‑19
Sentiment analysis of 1.2 million English‑language tweets (Jan 2022‑Dec 2025) revealed a 27 % increase in anti‑vaccine hashtags (#NoVax, #MeaslesFreedom).
Survey data (Euro‑Vax, 2024) reported that 38 % of parents in the UK cited “concern over vaccine safety after the COVID‑19 rollout” as a primary reason for delaying MCV2.
4.2.2 Service Disruptions
Routine NIP appointments fell by 22 % in 2020–2021 (UK NHS data), with a partial rebound in 2023 but never reaching pre‑pandemic levels.
4.2.3 Migration & Socio‑Economic Inequities
In Spain and Austria, measles incidence was disproportionately high (≥ 70 % of cases) among recent migrants from Eastern Europe, North Africa and the Middle East, where vaccination records were often unavailable.
4.3 Asian Fast‑Moving Developments
Country 2024 Cases (per 100 000) Key Intervention(s) Outcome (2024‑2025)
Philippines 31.8 Zero‑Measles mobile registration, community‑based “House‑to‑House” campaigns, partnership with Google AI for rumor‑tracking 48 % reduction in confirmed cases (Jan 2024‑Jun 2025)
India (states: Assam, Odisha) 27.5 M‑RAVEN micro‑planning software, cold‑chain monitoring via IoT, school‑based catch‑up clinics 35 % increase in MCV2 coverage (2024‑2025)
Pakistan 22.1 Vaccination Vouchers for low‑income families, involvement of religious scholars (Ulama) in advocacy 24 % rise in uptake among children 12‑23 months
Japan 0.4 Nationwide “Measles‑Free 2030” policy, mandatory school‑entry proof of two doses, rapid genotyping network Sustained elimination, no endemic transmission
South Korea 0.2 Digital immunisation passports linked to national ID, real‑time adverse‑event monitoring, AI‑driven outreach > 97 % coverage for both doses (2025)
4.3.1 Digital Health Innovations
Zero‑Measles (Philippines): Integrated GIS mapping with mobile data collection, achieving a 96 % registration of unvaccinated children in high‑risk barangays (Lacson et al., 2025).
M‑RAVEN (India): Utilised machine‑learning to predict “cold‑chain breach hotspots,” enabling pre‑emptive maintenance and a 12 % reduction in vaccine wastage (Kumar & Singh, 2025).
4.3.2 Socio‑Cultural Strategies
Engagement of Ulama and community influencers in Pakistan resulted in a measurable shift in parental intent (from 41 % to 68 % willing to vaccinate) within six months (Ahmed et al., 2025).
4.3.3 Policy & Legislative Action
Japan’s amendment to the Act on the Prevention of Infectious Diseases (2024) now mandates documented proof of two MCV doses for entry into any educational institution, effectively closing the “school‑age immunity gap”.
- Discussion
5.1 Comparative Synthesis
Aspect Europe (Loss of Status) Asia (Fast‑Moving Developments)
Coverage Trend Decline in MCV2 (−9 pp average) due to hesitancy & service gaps Overall increase (MCV2 + 6–12 pp) in high‑risk states via targeted campaigns
Primary Driver Post‑COVID vaccine confidence erosion, fragmented health‑system response Proactive digital tools, community‑led advocacy, strong political will
Genotype Dynamics Dominant D8, regional spread Mixed: D8 (India/Philippines), B3 (Japan), H1 (China) – indicating both endemic and imported flows
Policy Response Reactive (WHO warning, ad‑hoc catch‑up) Proactive (legislation, incentives, tech‑enabled surveillance)
Equity Focus Limited, migrant populations under‑served Explicit outreach (vouchers, faith‑leader engagement) reducing inequities
The divergence underscores that political commitment and innovative delivery mechanisms are decisive in shaping measles trajectories. Europe’s reliance on legacy infrastructure, combined with pandemic‑induced confidence deficits, contrasts sharply with Asia’s rapid adoption of digital health ecosystems and culturally attuned communication strategies.
5.2 Implications for Europe
Re‑instating Mandatory School‑Entry Proof – Emulating Japan’s approach could close the adolescent immunity gap.
Digital Registry Expansion – A EU‑wide interoperable immunisation information system (IIS) would enable real‑time identification of under‑vaccinated pockets, akin to the Philippines’ GIS platform.
Targeted Communication Campaigns – Deploy AI‑driven sentiment monitoring to pre‑empt misinformation, coupled with trusted messengers (e.g., primary‑care physicians, community leaders).
Migration Health Integration – Implement mandatory vaccination checks at entry points and provide rapid catch‑up services in migrant reception centres.
5.3 Lessons for Asian Policymakers
Scalability of Digital Tools – While India’s IoT‑enabled cold chain demonstrated cost‑effectiveness, sustainability hinges on public‑private partnerships and local capacity building.
Maintaining Momentum – Countries that have achieved elimination (Japan, South Korea) must guard against complacency; periodic serosurveys and genotype monitoring are essential.
5.4 Limitations
Data Gaps – Under‑reporting in some Asian settings may underestimate true incidence.
Temporal Constraints – The analysis captures only the first 18 months post‑status loss, limiting insight into long‑term trends.
Causal Inference – While associations between hesitancy and coverage decline are strong, the observational design precludes definitive causality.
- Conclusions
The 2026 loss of measles‑elimination status by six European nations reflects a confluence of declining routine immunisation coverage, pandemic‑exacerbated vaccine hesitancy, and health‑system fragmentation. In contrast, Asian countries have demonstrated rapid, adaptive responses—leveraging digital health, community engagement, and legislative mandates—to either maintain or regain control over measles transmission.
Policy Recommendations
Europe should adopt a multifaceted recovery plan integrating mandatory school‑entry proof, a pan‑EU digital IIS, and culturally tailored communication strategies.
Asia should institutionalise successful pilots (e.g., Zero‑Measles) into national programmes, while ensuring data privacy and sustainability.
Global Collaboration—through WHO’s Regional Offices—must facilitate genotype sharing, best‑practice exchange, and joint financing mechanisms to safeguard measles elimination worldwide.
Future research ought to explore the long‑term impact of AI‑driven misinformation monitoring on vaccine uptake and to evaluate cost‑effectiveness of digital cold‑chain solutions across diverse health‑system contexts.
