A Flea and Blood Type Theory I'm Researching

I have a theory that most of those who died of the Black Plague during the Middle Ages were RH negative in blood type.  Why?  Because those I've met who are RH negative have and had a really bad time with fleas compared to those with A positive blood.  I'm not sure about other blood types and fleas.  It seems that those who are RH negative have to watch it with the fleas.  Anyway, feel free to let me know what blood type you are and how fleas treat you to see if this theory of mine holds any water.
