Vaccine
Vaccine is an antigenic substance prepared from the causative agent of a disease or a synthetic
substitute, used to provide immunity against one or several disease.
Smallpox vaccine, the first successful vaccine was introduced by Edward Jenner in 1796.
Edible Vaccine
A vaccine in which an antigenic substance is engineered into an edible part of a plant.
The concept of edible vaccine was developed by Arntzen in the 1990s.
 Should not be toxic
 Low levels of side effect
 Should not contaminate the environment
 Should not cause problem in individual
 Technique of vaccination should be simple
 Should be cheap
 Should provide long lasting immunity
Recombinant
Protein(vaccine)
Transgenic plant Protection against
Rabies glycoprotein Tomato Rabies virus
Foot & mouth virus Arabidopsis Foot & mouth virus
Herpes virus B surface antigen Tobacco Herpes simplex virus
Cholera toxin B subunit Potato Vibrio cholerae
Human cytomegalovirus
glycoprotein B
Tobacco Human cytomegalovirus
Traditional vaccine Edible vaccine
Too expensive to be used on large scale Comparatively less expensive
Lack of physical infrastructure makes it
impossible to disseminate the vaccine
May be easily available
Required trained personnel to administer
injections
Do not require any trained personnel to
administer
Required elaborate production facilities,
purification, sterilization, packaging
No purification strategies required
Cant directly stimulate the immune system Vaccine when taken orally, can directly
stimulate the immune system
Presentation on Edible vaccine
Presentation on Edible vaccine
Presentation on Edible vaccine
 Cost effective
 Easy to administer
 Easy to store
 Acceptable to poor developing countries
 Active both mucosal & systemic immunity
 Heat stable
 Do not require cold chain maintenance
 No fear of contamination
 Delivery of multiple antigens
 Transgenic contamination can occur.
 Antibiotic resistance marker gene can spread from GM food to
pathogenic bacteria.
 Selection of best plant is difficult.
 Difficulty in dose maintenance.
 Consistency of dosage from fruit to fruit, plant to plant &
generation to generation is not similar.
 Stability of vaccine in fruit is not known.
 The first trial on humans in 1997 (using the heat labile B- toxin from E. coli) is a milestone
on the road to creating inexpensive vaccines that might be particularly useful in
immunizing people in developing countries, where high cost and logistical issues, such as
transportation and the need for certain vaccines to be refrigerated, can thwart effective
vaccination programs.
 The hope is that edible vaccines could be grown in many of the developing countries
where they would actually be used.
 Whatever may be the current situation, a day is not far off when we will be able to pluck a
fruit from the garden, eat it and be protected from diseasesmaking needles needless
