Modelling Alternatives to Current Measles SIA Strategies and Pathways for Their Evolution

Supplementary Immunisation Activities (SIAs) have long served as a central tool for closing measles immunity gaps, yet many countries now face growing challenges that complicate the traditional model of large, nationwide campaigns. Clearer guidance is needed on how SIAs might evolve as countries strengthen routine immunisation (RI) and consider long-term transition plans away from broad, nation-wide SIAs. Models can help identify feasible, cost-effective alternatives to current SIA practices with comparable impact on immunity gaps, determine the minimum data required for both reliable targeting and implementing other alternative approaches, and explore credible off‑ramps from RI+SIA regimes.

The MAH has invited proposals that address one or more of the conceptual areas below. Findings from selected proposals will inform high-level programmatic choices through country archetypes rather than bespoke country micro-plannings.

Successful proposals will address one or more of the following conceptual areas:

A standardised modelling framework for non‑national (i.e. sub-national) and responsive vaccination activities
Optimising SIA design under real‑world constraints
Assessing how data quality and heterogeneity inform targeted SIA design and decision-making
Transition pathways and off‑ramps from RI+SIA to RI‑led strategies
