nasal spray vaccine
Inhaled immunity dose
A nasal spray vaccine is a vaccine administered through the nose rather than by injection.
The spray delivers weakened or inactivated pathogens to the nasal passages, where they stimulate immune response in the mucous membranes—the body's first line of defense against airborne infections.
The flu vaccine is the most common example: My kids prefer the nasal spray vaccine to getting a shot.
