the challenge
Traditional tools can't keep up
  • Fluctuating supply makes it impossible to plan ahead with static spreadsheets or legacy tools.

  • Shifting priority groups and eligibility criteria require constant replanning across teams and regions.

  • Staffing and site logistics need to be optimised in real time — not days later when the window has passed.

  • Public and parliamentary scrutiny demands transparency and evidence-backed decisions at every step.

what zeno does
Six capabilities. One integrated system.

Zeno gives health systems the tools to plan, adapt, and act — across every stage of a vaccine rollout.

real-time scenario modelling

Instantly simulate multiple what-if scenarios for supply changes, new vaccine introductions, or shifts in priority groups — without waiting for data to be processed.

bottleneck dectection

Identify upcoming capacity constraints and data issues before they impact rollout success — giving teams time to respond rather than react.

optimised site planning

Use advanced spatial analysis to determine the ideal number, location, and capacity of vaccination centres — accounting for population density, access, and cold chain logistics.

adaptable architecture

Easily update models for booster campaigns, new variant waves, or revised eligibility criteria — without rebuilding from scratch each time.

demand forecasting

Accurately predict vaccine demand by age group and region — helping allocate resources and schedule staff effectively across your entire distribution network.

collaboration-ready

Intuitive interface designed for cross-team use — minimal training required, with multi-user access built in for policy, logistics, and international coordination teams.
