Abstract:
Edible vaccines are alternative and new approach of vaccination as compared to traditional vaccines, they are cheap, heat stable, require no cold chain maintenance. There are many clinical trials which are undergoing for development of edible vaccines to provide protection against many diseases. This may lead to a future of safer and effective immunization. Vaccine is being developed for Measles, cholera and hepatitis B and for many other diseases are in the process of development. For preparation of edible vaccine, molecular farming technique is used in which selected genes are introduced into the plants. The transgenic plant is then induced to manufacture the encoded protein. Also the edible vaccines can be used against emerging COVID 19. Thus by use of suitable plant vector and Spike protein of the corona virus an edible vaccine can be developed against the COVID-19. This aim of this review to provide comprehensive coverage on the importance of edible vaccines to provide protection against various diseases.
