Summary

This study tests a new COVID-19 vaccine that you breathe in as a mist, aiming to boost immunity in the lungs and blood. About 350 healthy adults who have already had three mRNA COVID shots will get either the experimental vaccine or a placebo. Researchers will check safety and immune responses through blood tests and, for some, a lung cell sample. The goal is to see if this inhaled approach can offer better protection against COVID.
