Vaccination works through cells in the bloodstream that rush to attack bacteria and viruses that they have learned to recognise as a result of the vaccine. *I hope that nasal vaccine makes its way to the USA. It might even be more effective fighting infection since most of those nasty Covid germs are inhaled.
White blood cells and killer T cells do the work of destroying the pathogens so that they are unable to overwhelm us completely. If the immune response is poor then serious consequences are likely. As we age, our immune system, like every other part of us, does become less effective in fighting infections.
With this in mind, it matters not whether you meet the vaccine by way of an injection (arm or backside makes no difference) or taken as syrup on a sugar cube or inhaled up the nose, as long as it enters the blood stream the effect will be the same. The immune system is fortified and ready when eventually the pathogen enters the body.
*Over simplified for the sake of not getting too technical.
