How the Netherlands Used Real-Time COVID-19 Vaccine Delivery Planning

A look at how the Netherlands used real-time vaccine delivery planning to coordinate 25 regions, 140+ sites and strengthen equitable COVID-19 rollout at scale.

Background: COVID-19 Vaccine Rollout Complexity in the Netherlands

In early 2021, the Netherlands faced the urgent task of vaccinating its adult population against COVID-19. National strategy prioritized high-risk groups first, followed by age-based rollout. But translating policy into operational delivery across 25 regions and more than 140 vaccination sites proved highly complex. Vaccine supply fluctuated frequently, delivery schedules shifted, and different vaccines required different cold-chain and handling protocols. At the same time, public scrutiny and political pressure were high, and local health authorities were under intense pressure to move quickly while ensuring fairness and transparency.

Objectives: Equitable, Flexible Vaccine Delivery

The primary objectives of the vaccine rollout were to:

• Rapidly vaccinate priority populations

• Ensure equitable access across regions

• Maintain flexibility under uncertain supply conditions

• Optimize use of limited staff and infrastructure

• Strengthen public trust through transparent decision-making

To achieve this, local and national authorities recognized the need for more dynamic, data-driven delivery planning.

Implementation Strategy: Real-Time Delivery Intelligence with ZENO

Public health authorities deployed ZENO, a delivery intelligence platform designed to support real-time coordination between national and regional actors.

ZENO enabled teams to:

• Forecast demand by region, age group, and risk profile

• Forecast impact on demand due to external events such as closure of schools, celebration of carnival, and introduction of face masks, etc.

• Optimize site locations, staffing, and logistics

• Run “what-if” scenarios to test rollout strategies

• Anticipate bottlenecks and reallocate resources

• Share transparent operational data across stakeholders

This approach shifted vaccine delivery from static planning to adaptive, scenario-based coordination.

Challenges and Adaptations: Managing Supply, Demand & Policy Shifts

Despite improved planning tools, significant challenges remained: 

• Supply volatility: Vaccine deliveries changed week to week

• Demand uncertainty: Uptake varied by age group and geography

• Operational pressure: Sites needed to scale up and down rapidly

• Timing of policy decisions: Booster campaigns had to be prepared before final political decisions were made

ZENO enabled teams to model multiple rollout scenarios in advance, allowing planners to adjust staffing, site leases, and logistics capacity before demand peaks materialized. This reduced the risk of delays and underutilized resources.

Outcomes and Impact: Faster, More Transparent Vaccine Delivery

The use of delivery intelligence led to measurable operational improvements:

• COVID-19 rollout coordinated across 25 regions and 140+ sites

• Faster response to changes in supply and eligibility criteria

• Improved workforce planning through demand peak forecasting

• Increased public and political trust through transparent data sharing

• More efficient use of vaccination sites and staff

Overall, the approach demonstrated that large-scale prevention campaigns can be both fast and equitable when delivery systems are treated as strategic infrastructure.

Lessons Learned: Building Adaptive Immunization Systems

Several key lessons emerged from this experience:

•  Delivery planning must be integrated into policy design from the outset

• Static tools are insufficient in high-uncertainty environments

• Scenario modeling improves preparedness for political and epidemiological shifts

• Transparent data strengthens trust across institutions and with the public

The 25 national health service centra all converted their local strategies around vaccination supply into a standardized national best practice approach with improved interaction and alignment between regions and sites

Recommendations for Governments and Immunization Partners

For governments and global immunization partners planning large-scale vaccine delivery:

•  Invest early in adaptive delivery intelligence, not only monitoring systems

• Enable real-time coordination across national and sub-national levels

• Build scenario planning into routine preparedness, not just crisis response

• Treat delivery capacity as part of health system resilience, not emergency logistics

Conclusion: Delivery Intelligence as Public Health Infrastructure

This bright spot from the Netherlands illustrates how strengthening delivery intelligence can transform vaccine policy into effective, equitable action on the ground. As countries prepare for future immunization campaigns — routine, catch-up, and outbreak response — embedding adaptive delivery systems into public health infrastructure will be essential for building resilient immunization systems.
