text: what is the immunity out side of your body?   huh? i'm not sure what your first langauge is, but your question makes no sense whatsoever in english.  i'm trying to decipher it and i think you might be trying to ask about herd immunity. does that sound right?  ____ >>>>immunity outside would consits of skin,  >>> nostrils and fillaments within the ears.  no, it wouldn't. those aren't immunity, they are simply barriers. nostrils aren't even that, they are just holes.  i think perhaps you should find a dictionary and look up "immunity".
