Your example, that of influenza virus, is a good case in point. The influenza virus has enough genetic variability to dodge antibodies generated by the host to attack previous generations of the virus.

But...and I'm honestly inquiring, not trying to make a rhetorical point...does the influenza virus ever change into something other than influenza virus, or do successive generations remain simply new and improved influenza viruses?

I don't have the biology background to say, myself. Any information you might have on this topic would be most helpful.

I wasn't aware that antibiotics affected the influenza virus. Is this part of creationist biology?
