The inhaled aerosol vaccine is far more effective at inducing protective immune responses than traditional injections, targeting the lungs and upper airways where viruses first enter the body and providing long-lasting protection against respiratory infections.
McMaster scientists found a common tuberculosis vaccine triggers an immune-communicating mechanism from the gut that offers broad protection against respiratory pathogens in the lung.
A team of researchers at McMaster University is working on an inhaled COVID-19 vaccine that offers better protection and is less costly to produce, store and ship.
