Research Hepatitis B vaccine

injectable hepatitis b vaccines require expensive production processes , refrigeration, can make them difficult access in developing countries. result, researchers have been working engineer plants capable of producing ingredients necessary make vaccines people can eat these plants receive vaccine. potatoes, bananas, lettuce, carrots, tobacco of plants being genetically engineered produce hepatitis b vaccine ingredients.

the process of genetically engineering plants produce vaccine includes extracting gene codes hepatitis b surface antigens hepatitis b genome, , placing in bacterial plasmid. bacteria infect plant, produce surface antigens. when human eats plant, body stimulated produce antibody response surface antigens. although concerns remain in improving efficacy of edible vaccines, controlling dosage of vaccine in each plant, , managing land allocation process, scientists consider promising avenue vaccinating underprivileged areas of world.
