Influenza vaccine administered to the lungs efficiently than injections

The vaccine directly into the lungs more effectively in the fight against influenza as conventional injection, say Australian experts. People around the world need a vaccine if an influenza pandemic. For this reason, scientists are as confused reduce the dose. They conducted an experiment with sheep injected with the vaccine directly into the lungs. It turned out that the vaccination in the lungs has the best effect in small doses than the standard dose of the injection. Scientists have three different doses of the vaccine in the three groups of sheep lung with a bronchoscope, or tube is introduced. Fourth group of sheep vaccine was introduced in the usual way, by injection. Can was standard, surpassing entered directly into the lungs in about 1000. Experts have found that antibodies which are formed in the lungs were block able to interact the ability of the virus to receptors in order to infect cells. Protection is more effective than injections, and thus with less vaccine, said one of the researchers who led the study. According to experts, it is necessary to ensure the effectiveness of this method in humans. If the results are the same positive, it is necessary to provide a method with which to develop the vaccine without difficulty into the lungs.
