"Are there ways to keep this virus from getting through or past the respiratory tract and avoiding the whole blood vessel problem?"
Probably, but I have no real idea what these might be. I would imagine that having a strong innate immune system with plenty of CD8+ killer T cells and NK (natural killer) cells in circulation would be helpful, as I'm sure that at least a few viruses will always make it into the bloodstream if they are in the business of infecting and lysing respiratory cells. Also I would expect that defeating the virus in the upper respiratory tract and avoiding lung infection would be critical, as the upper respiratory tract has quite a few layers of cells between the airway and the bloodstream while the alveolar wall in the lungs is only two cells thick (alveolar wall and capillary wall) with airspace on one side and blood on the other to facilitate rapid gas exchange.
