While almost 300 vaccines against COVID-19 are presently in development, only a small minority (3%) explore the potential of oral vaccines (WHO). Oral vaccines produced in plants offer several advantages over traditional processes, including lower research and production costs, ease of scalability, and a negligible risk of contamination with human pathogens
