"There are a lot of children dying because they can't get a vaccine that is cheap and effective enough," said co-author David Putnam, associate professor of biomedical engineering and chemical and biomolecular engineering. 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. 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. Now, an interdisciplinary team of Cornell researchers has devised a new way to make vaccines that promises to prevent diseases much more cheaply. Traditional vaccines can be ineffective and expensive.
