Research Journal of Pharmaceutical Dosage Forms and Technology

As the science and technology advances, a leap in medical field occurred and all the painful vaccination procedures replaced with modernized techniques like edible vaccines, a non-invasive technique. Vaccine contains weak pathogens of bacteria or virus or a killed bacterial suspension or toxins produced by bacterial strains, when taken inside human body, our immune system finds out the foreign particle and it produces a group of antibodies to eradicate it and making a memory of it. Edible vaccines are genetically modified crop, in which vaccines are produced in the plant parts when antigenic proteins are transgenically introduced into edible crop and work same as that of original vaccines. Present review is focused on several methods used in production of edible vaccines and the types of food used for production of edible vaccines. And the challenges we are still facing in development which needs to be focused more by the future generations.
