edible vaccine


Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.
A vaccine in which an antigenic protein is engineered into an edible plant; after ingestion, the protein is uncloaked and recognized by the immune system

edible vaccine

A genetically manipulated food containing organisms or related antigens that may provide active immunity against infection. Edible vaccines against many microorganisms are being developed, with the goal of using them to vaccinate children in nonindustrialized countries where there are obstacles to the use of traditional injectable vaccines.
