North Carolina State Researchers Test Dental Floss as Needle-Free Vaccine Delivery Method
Researchers at North Carolina State University are exploring the use of dental floss to deliver vaccines, aiming to bypass needle anxiety and cold storage requirements. The method leverages the permeable tissue between teeth and gums to trigger a mucosal immune response, potentially protecting against viruses that attack the nose, mouth, and lungs. While early studies show promise, human trials are the next step, and the approach is designed for older children and adults, not infants.
