The CDC is promoting National Influenza Vaccination Week.
Dr. Jennifer Layden, Chief Medical Officer of the Illinois Department of Public Health, says it’s time for state residents to get the flu shot if they haven’t already.
"Because it takes a couple weeks to become fully effective and the peak of the flu season starts to occur sometime typically between December and February, we encourage individuals to get it as soon as possible," she said.
Layden recommends everyone gets the injectable vaccine, as the nasal spray has shown limited effectiveness this year. Flu activity has been sporadic, and there are no reports of vaccine shortages.
