This news item from the Cornell Chronicle is about: Traditional vaccines can be ineffective and expensive. Now, an interdisciplinary team of Cornell researchers has devised a new way to make vaccines that promises to prevent diseases much more cheaply. The new technique, described online in the journal Proceedings of the National Academy of Sciences, which involves fusing a novel component to the vaccine to boost its effectiveness, can effectively stimulate antibodies to target bacterial infections, including ulcers, flesh-eating skin infections and leptospirosis. The researchers also are working on modifying the method to create vaccines that stimulate cell-mediated immune responses required to fight viral diseases and some cancers.
