South Korean scientists have proposed to abandon the traditional injectable influenza vaccine, replacing them with its incorporation under the tongue. Past their experiments on animals have shown that this method of vaccination not only deprived of unpleasant side effects, but also superior to traditional injections for efficiency.

Scientists from Seoul National University injected mouse for language alive and killed influenza vaccine. After several weeks gave animals inhale the potentially deadly flu virus concentrations.

According to head of research Sesila Cherkinski, all mice were protected against the virus. Moreover, imposed under the tongue vaccine stimulated not only the general immunity (stirred education protective antibodies in the blood) as a vaccine injection, but also provided local protective effect (leads to the formation of antibodies in the respiratory tract). The latter is especially important for disease prevention at the earliest stages, because flu viruses enter the body through the respiratory tract that is, stressed Cherkinski.

The introduction of a vaccine under the tongue eliminates the need for painful injections, and protects against complications such as inflammation at the injection site. In addition, this method allows for more people immunized, especially in remote areas, and does not require mandatory attendance medical specialist, said the journal Proceedings of the National Academy of Sciences.
