Edible plant vaccines are immunogenic preparations containing antigenic proteins rather than pathogens, therefore,
they sanctify situation where there is a possibility of resurgence of disease when the antigenic preparation contains
the organism in any form whatsoever. Expression of antigens as vaccines and of antibodies against antigens of pathogens
in transgenic plants is a convenient and inexpensive source for various bacterial, viral, helminths, protozoan and autoimmune
diseases with lower capital costs. This review describes various diseases along with the production of edible transgenic
plant vaccines/proteins for the same. Thus, substituting and improvising conventional immunization methods.
