Despite this advantage, traditional subunit vaccines are unaffordable and technology-intensive, require purification, refrigeration and produce poor mucosal response.
Edible vaccine production process can be scaled up rapidly by breeding. Many of the organizations have lost interest in edible vaccines research research paper on edible vaccines to unavailability of investors, assurance in returns on investments, grants, research aid and financial support.
Mechanism of Action Since almost all human pathogens invade at mucosal surfaces via urogenital, respiratory and gastrointestinal tracts as their leading path of entry into the body.
Potentially at stake in the two remaining phases of human clinical trials is the health of millions of children in developing nations. Edible Vaccines: The transgenic tomatoes are capable to produce surface protein specific to the virus and it has been shown that mice fed with transgenic tomatoes showed an immune response towards the virus. This approach is slow with lower yield however; it showed satisfactory research paper on edible vaccines in dicotelydenous plants like potato, tomato and tobacco.
In addition, plants with oil or their aqueous extracts possess more storage opportunities .
intro paragraph for a persuasive essay Therefore, as substitutes have to be produced for traditional vaccines, it was envisaged that plants could be promising agents for efficient production system for vaccines, which in turn gave rise to the novel concept of edible vaccines. The transgenic plants can further be made available in various shapes like; pills, puddings, chips, etc.
Hence, there is search for easily administrable, storable, fail-safe and widely acceptable bio friendly vaccines and their delivery systems especially in developing countries. June 01, ; Published: The clinical trials were research paper on edible vaccines in advance by the Food and Drug Administration.
