The 'melt in the mouth' concept is associated with a novel delivery system for the flu vaccine.

Researchers have developed a vaccine using genetically modified spores of the bacteriumBacillus subtilis. These spores are engineered to express the influenza antigen and are incorporated into a fast-dissolving film. When placed under the tongue, the film melts in the mouth and delivers the vaccine directly to the mucosal immune system.

This innovative approach eliminates the need for needles and cold chain storage, making vaccine administration easier and more accessible.
