Edible vaccines are mucosal-targeted vaccines that have been created by injecting antigenic proteins into edible plants. When consumed, the proteins are uncloaked and recognized by the body's immune system when they enters the bloodstream. The proteins are then responsible for stimulating both systemic and mucosal immune responses.
As of 2014, there is much research underway to develop edible vaccines for diseases like hepatitis B, measles and cholera. The main benefits associated with edible vaccines are cost efficiency, easy accessibility, easy storage, quick distribution and simple administration, especially in young children. Current research focuses on determining how to effectively ensure that sufficient proteins are ingested for a good immune response to kick in.
