Sentence is a bit ambigous. Are the nasa vaccines likely to give sterilizing immunity or the opposite?

  They're more likely to work, because they go in the places (your nose) that need to be sterilized. But it's only theoretical.

    > They're more likely to work, because they go in the places (your nose) that need to be sterilized. That doesn't make much sense; vaccines aren't topical treatments for current infections but systemic preparation against future infections.

      There's special antibodies for the nose and other membranes. The immune system is incredibly complicated. https://en.wikipedia.org/wiki/Immunoglobulin_A https://en.wikipedia.org/wiki/Immunoglobulin_A
