Respiratory illnesses such as influenza, COVID-19, and respiratory syncytial virus (RSV) can cause serious health problems. Complications from these illnesses are especially hazardous for infants, older adults, pregnant individuals, and people with chronic health conditions and compromised immune systems.
Recommended immunizations against these viruses can lower your risk of severe illness, hospitalization, and other complications. The Illinois Department of Public Health (IDPH) has released new vaccine guidance to help Illinois residents protect themselves and their families during the 2026-2027 respiratory virus season.
Let’s review the vaccines most likely to help protect you and your loved ones from viruses expected to circulate this fall season.
Flu Vaccination Recommended for Almost Everyone
IDPH recommends an annual flu vaccination for everyone 6 months of age and older.
Flu viruses change over time, and protection from a previous vaccination gradually decreases. Receiving the current seasonal vaccine helps prepare the immune system to fight the flu viruses expected to circulate this season.
