Abstract

Despite worldwide vaccination against devastating diseases for decades, millions of children in remote and impoverished regions of the globe die every year from vaccine-preventable infectious diseases. The reasons for incomplete coverage of vaccination programs are based in part on the relatively high costs of conventional vaccinations, including mass production, refrigeration, transportation, and training as well as funding personnel for their administration. Plant-based edible vaccines (PEVs) have been introduced as a revolutionary cost-effective vaccination modality. However, they suffer from major deficiencies that have restricted their application to bench-scale. This article discusses the deficiencies of PEVs and also provides concise overview on the health-promoting, biological and biotechnological features of spirulina (Arthrospira). In short, we envision that spirulina could be considered as a potential alternative biofactory system to the plants toward the production of edible vaccines in high-yield with low-costs that other hosts cannot yet offer.
