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 is inviting proposals that address one or more of the conceptual areas below. Funding up to USD 73,000 is available for up to 12 months. Please note that in all areas, we are looking for findings that inform high-level programmatic choices rather than bespoke country plans. As such, models should be representative of a range of different countries. This could be addressed by developing country archetypes, describing key metrics such as RI coverage, susceptibility gaps, and the age distribution of cases.

Proposals should address one or more of the following conceptual areas:​

  1. A standardised modelling framework for non‑national (i.e. sub-national) and responsive vaccination activities

  2. Optimising SIA design under real‑world constraints

  3. Assessing how data quality and heterogeneity inform targeted SIA design and decision-making

  4. Transition pathways and off‑ramps from RI+SIA to RI‑led strategies

Eligibility

  • Applicants must be members of the MAH

  • Applicants must be based at a university or another academic/research institution 

  • Prior modelling experience is essential

One of the MAH’s goals is to become a diverse community of measles modellers, inclusive of modellers from high measles burden countries. We are committed to embedding equality, diversity and inclusion in our practices. As such, we encourage applications from applicants who may be underrepresented amongst the mathematical modelling community.

Collaboration Requirements

Proposals that include meaningful, structured mentoring components—beyond tokenistic involvement—will be viewed more favourably. Proposals are expected to include details regarding the following:

  • Multi-Modeller Collaboration: Proposals must include collaboration between multiple modellers to ensure methodological diversity and robustness.

  • In-Country Involvement: Local partners or users of modelling outputs for decision making should be involved from project conceptualisation through to modelling, interpretation, and dissemination. Their role should be clearly defined and meaningful.


Please see the Guide for Applicants for more information. The Application Form can be accessed below – all applications are due by 29th May 2026 by 23:59 BST.
