I suspect that you're confusing variables with values of variables.
I'm guessing that myevent is a character variable, and that 'flu' is
one possible value of that variable. In which case you don't need a
data step, you could try something like

PROC CHART data=epi2;
  where myevent^='flu';
  VBAR MYEVENT / TYPE=PERCENT;
run;
