Abstract

Globally, the pathogen-driven enteric diseases remain a leading cause of morbidity and mortality, disproportionately affecting populations in low-income regions. While significant strides have been made in vaccine research, challenges such as high production costs, complex manufacturing processes, and inefficient distribution continue to hinder global vaccine accessibility. To overcome these challenges, plant-based edible vaccines have emerged as a promising and innovative alternative, offering advantages such as affordability, ease of administration, and reduced reliance on cold-chain infrastructure. This study presents a comprehensive overview of recent advances in the development of edible plant-derived vaccines, highlighting the strategic evolution from conventional genetic engineering to more refined and scalable biotechnological methods. In the work, various applications targeting diseases such as measles, hepatitis B, rabies, dengue, and norovirus, are discussed as well as veterinary vaccines for livestock and aquaculture. The significant progress in creating vaccines targeting prevalent human pathogens is examined and the discussion is extended to include edible vaccines developed for livestock, underscoring their role in both public and veterinary health. Furthermore, the review emphasizes the transformative potential of 'omics' technologies, such as genomics, proteomics, and metabolomics, as well as artificial intelligence in streamlining vaccine design, improving antigen expression, and accelerating development timelines. This assessment review was conducted by performing a comprehensive literature survey of peer-reviewed articles. By integrating multidisciplinary insights, the work underscores the feasibility and future prospects of edible plant vaccines as a sustainable solution to global immunization challenges, with practical applications in improving vaccine accessibility, enhancing outbreak preparedness, and supporting immunization efforts in resource-limited settings. It aims to inform and inspire continued research and collaborative innovation in this emerging field with significant implications for global public health.
