The Illinois Department of Public Health says it isn’t too early for residents to get their flu shot.
Flu season typically runs from October through March, and it takes about two weeks for the vaccine to take effect. That’s why Public Health Chief Medical Officer Dr. Jennifer Layden says it’s a good time to get immunized.
"There's several options," she said. "There's multiple flu vaccines. The main message is we do not recommend, nor does the CDC, that individuals get the nasal spray."
