No, but his great-great uncle in law or some such (I'd love to know the genealogy here) apparently started the "Spanish flu" with an experimental meningococcal vaccine. He was a Rockefeller trained doctor.
I do wonder if Bill hopes to repeat the event. He's been predicting it for some time (Global pandemic with mass deaths).
PDF is of the Frederick Gates paper on his vaccine experiment.

This gives an alternate view of the history of Spanish flu, the version I believe is more likely correct.
