South Korean scientists have suggested abandoning the traditional injectable flu vaccine, replacing them with their reception on the tongue. Have conducted their experiments on animals showed that. This method of administration of the vaccine is not only free of unpleasant side effects, but also the efficiency in conventional injections Scientists from Seoul National University injected mice living under the tongue and killed influenza vaccine. A few weeks later, the animals were inhaling deadly concentrations of influenza virus. According to study leader Cecil Cherkinskaya all mice were protected against the virus. Furthermore, under the tongue vaccine stimulates not only the general immunity (due to the formation of protective antibodies in the blood) was introduced as an injectable vaccine, but also has a local protective effect (leading to the formation of antibodies in the respiratory tract). The latter is particularly important for the prevention of the disease in its earliest stages, because flu viruses enter the body through the respiratory tract, said Cherkinskaya. Vaccine under the tongue eliminates the need for painful injections and prevent complications such as inflammation at the injection site. Furthermore, this method allows to immunize more people, especially in remote areas, and does not require the presence of a medical officer, says the journal Proceedings of the National Academy of Sciences.
