mucosal vaccines

Mucosal vaccines are designed to target the mucous membranes, which are moist tissues lining the body’s cavities, like the nose, mouth, and intestines. Unlike traditional vaccines that are injected, mucosal vaccines are often delivered orally or as a nasal spray. They stimulate the immune system at the site of entry, helping the body defend against infections that enter through these pathways. This can provide a more localized immune response and enhance protection against diseases, such as influenza or certain gastrointestinal infections. By focusing on the mucosal surface, these vaccines can potentially improve both safety and effectiveness.
