Influenza Surveillance

Vaccination is the best way to protect against influenza infection. All Illinois residents aged 6 months and older should be vaccinated annually.

Flu vaccination can keep you from getting sick with flu.
Flu vaccination can reduce the risk of flu-associated hospitalization, including among children and older adults.
Flu vaccination is an important preventive tool for people with chronic health conditions.
Vaccination helps protect women during and after pregnancy. Getting vaccinated also protects the developing baby during pregnancy and for several months after the baby is born.
Flu vaccination also may make your illness milder if you do get sick.
Getting vaccinated yourself also protects people around you, including those who are more vulnerable to serious flu illness, like babies and young children, older people, and people with certain chronic health conditions.
