S. Korea Scientists Develop Flu Vaccine Delivered Under Tongue

Executive Summary

Medical researchers in South Korea report success in providing a vaccination with a pill under the tongue instead of using a needle, or ingesting or inhaling the drug.

The leading researcher said the method eliminates a risk of an antigen redirection to the central nervous system, a risk common to vaccines delivered intravenously. (Click here for more
