UK to start testing the vaccine against the covid-19 through a nasal spray delivering doses directly to the lungs might give a better immune response than conventional jabs.

For testing through nasal, the Imperial College London team will use two frontrunners already in development - the Oxford one and one from Imperial that entered human testing in June, and about 30 healthy volunteers will be given the vaccines as a mist or aerosol - in the same way asthma drugs are delivered with a nebuliser machine and a mask or mouthpiece.

In regards to this, the lead researcher Dr Chris Chiu has said that the current pandemic is caused by a respiratory virus which primarily infects people through the cells lining in the nose, throat and lungs and as those surfaces produce a different immune response to the rest of the body, it is critical to explore whether targeting the airways directly can provide an effective response compared to a vaccine injected into muscle.

The test will tell us, whether the vaccine delivered through a Nasal spray directly to the lungs is more effective compared to a vaccine injected into muscle.
