what are edible vaccines ?

Dear Student,

Edible vaccines are the vaccines which can be consumed orally. They are developed in transgenic plants. Vaccines in plants are expressed and then these trannsgenic plants are consumed as edible vaccines. Thus, plants such as banana act as a vehicle to deliver vaccines.

The purpose of their production is to overcome some of the limitations of vaccine usage  in developing countries.

 Edible vaccines can lower the cost of vaccine production ,as they do not need refrigeration.

 Research on edible vaccine is under development phase.

 Edible vaccine for Hepatitis B virus (HBV) has been developed.
