Mucosal Immunization

Mucosal immunization involves delivering vaccines directly to the mucous membranes, such as those in the nose, mouth, or throat, to stimulate the immune system right at these entry points of many pathogens. This method aims to generate local immunity where infections often begin, providing a first line of defense. It can be more convenient and less invasive than injections, and may promote stronger, longer-lasting protection against diseases like flu or COVID-19. Overall, mucosal vaccines harness the body's natural defense systems at mucous surfaces to prevent illness effectively.
