HANSEN, Ekkehard. Production of recombinant antigens in plants for animal and human immunization - a review. Braz. J. Genet. [online]. 1997, vol.20, n.4 ISSN 0100-8455. http://dx.doi.org/10.1590/S0100-84551997000400024.
Plants present a cost effective production system for high value proteins. There is an increasing world demand for cheap vaccines that can be readily administered to the population, especially in economically less developed regions. A promising concept is the production of vaccines in plants that could be grown locally. Expression of antigenic peptides in the palatable parts of plants can lead to the production of edible active vaccines. Two major strategies are: i) to express antigens in transgenic plants, and ii) to produce antigenic peptides on the surface of plant viruses that could be used to infect host plants. This review considers the experimental data and early results for both strategies, and discusses the potential and problems of this new technology
