A Review on Edible Vaccines and Biopharmaceutical Products from Plants

Abstract

Abstract: Plants have substantial potential for the development of various biopharmaceuticals. Plants provide a cost-effective and direct source for the production of biopharmaceuticals such as vaccines, antibodies, proteins, enzymes, and hormones. In most cases, purification is an important and expensive step in the production of these substances. The problem can be resolved when it is produced in plants and the whole plant can be consumed. Direct ingestion of plant materials may help in overcoming the purification step. Being produced in seeds, fruits and tubers, it helps in providing more immunization in developing countries at a cheaper rate. Moreover, it can be administered more efficiently than any other dosage forms. This review focuses on various immunization and therapeutic products that are produced in plants along with currently available formulations in each category.
