Abstract
The integration of artificial intelligence (AI) into vaccine development has revolutionised the traditional paradigm of vaccinology,
significantly accelerating the timeline from pathogen identification to clinical deployment. This review examines the transformative
role of AI technologies, including machine learning, deep learning, and neural networks, in various stages of vaccine design and
optimisation for infectious diseases. We conducted a comprehensive literature search of PubMed, Scopus, Web of Science, and Google
Scholar databases for publications from 2020 to 2025 using keywords: artificial intelligence, machine learning, deep learning, vaccine
design, epitope prediction, infectious diseases, and immunoinformatics. Studies focusing on AI applications in vaccine development
pipeline stages were included. We explore AI applications in antigen selection, epitope prediction, immunogen design, adjuvant
identification, clinical trial optimisation, and manufacturing processes. Recent advances in graph neural networks, transformer-
based architectures, and generative models have enhanced prediction accuracy and enabled the discovery of previously overlooked
immunogenic epitopes. Despite these remarkable achievements, challenges persist in data quality, model interpretability, regulatory
frameworks, and equitable global implementation. This review synthesises current evidence from 2020-2025 and provides insights
into future directions for AI-driven vaccine development against emerging infectious threats.
