AI-driven big data analysis and predictive modeling of infectious disease immunity: from correlates to causal, multiscale understanding
Clinical Snapshot
PICO Framework
| P — Population | Not applicable - this is a narrative review examining AI applications in immunity prediction across various populations |
| I — Intervention | AI-driven big data analysis and predictive modeling approaches |
| C — Comparator | Traditional immunity prediction methods (primarily antibody titers and simplified correlates) |
| O — Outcomes | Predictive accuracy, generalizability, biological interpretability, and clinical utility of immunity prediction models |
Bottom Line
This narrative review highlights that while AI shows promise for infectious disease immunity prediction, current approaches often lack the biological interpretability and robust validation needed for clinical implementation. The authors argue convincingly that meaningful progress requires embedding machine learning within immune biology and causal reasoning frameworks rather than pursuing predictive accuracy alone. Key recommendations include moving beyond simplified correlates like antibody titers toward multiscale, dynamic models that account for innate immune programming, trained immunity, and adaptive immune dynamics. For Australian clinicians, this work underscores the importance of rigorous validation frameworks and biological interpretability in evaluating AI tools for infectious disease management. While the review lacks systematic methodology, it provides valuable insights for understanding limitations of current AI approaches and requirements for clinically useful immunity prediction models.

Abstract
The ability to reliably predict protective immunity against infectious diseases remains a central challenge in immunology, vaccine development, and public health. Despite major advances in immunological measurement, immunity prediction has historically relied on simplified correlates most notably antibody titers that often fail to generalize across pathogens, populations, and time. The emergence of large-scale, high-dimensional immune datasets spanning multi-omics, longitudinal cohort studies, electronic health records, and pathogen genomics has created new opportunities for artificial intelligence (AI)-driven modeling. However, early applications reveal that predictive accuracy alone is insufficient and is frequently undermined by spurious correlations, limited generalizability, and a lack of biological interpretability. This review synthesizes current advances and limitations in AI-based immunity prediction, arguing that meaningful progress requires embedding machine learning within immune biology, causal reasoning, and rigorous validation frameworks. We examine the biological foundations of immunity relevant to modeling including innate immune programming, trained immunity, adaptive immune dynamics, and immune memory and map these processes to appropriate data modalities and model classes. We critically evaluate predictive tasks across individual and population scales, from early infection outcomes and vaccine responsiveness to immunity waning and herd-level protection. Emphasis is placed on validation beyond internal cross-validation, on interpretability grounded in immune mechanisms, and on robustness under demographic diversity and pathogen evolution. We conclude that immunity is best understood and predicted as a dynamic, probabilistic, and multiscale system rather than as a static trait. AI has substantial potential to improve infectious disease preparedness and clinical decision-making.
