Most people would love it if vaccinations didn’t involve needles and the ouch that goes with them. But for respiratory infections, vaccinations given into the nose or mouth may be more effective than intramuscular (IM) inoculations.

Immune cells live inside the thin mucous membranes that line the nasal and oral cavities. Priming these cells with a vaccine could stop viruses where they first enter the body, blocking their spread, preventing even mild cases of illness and possibly preventing the spreading of the virus to others.
