Usually by November the flu bug arrives in Iowa.
To make sure people are vaccinated before it arrives, the flu shots for this season are now being delivered.
State Medical Director Patricia Quinlisk says it doesn't look like this year's flu will have any new surprise strains.
Quinlisk said, "Some of the Southern Hemisphere nations are finishing up their flu season right now, so that can give us a little bit of a hint, but they've been having pretty typical stuff."
Quinlisk says this year's vaccine has an additional strain added that should provide even more protection than last year's vaccine.
