As flu season gets underway, U.S. health experts are reminding parents about children’s vaccination, hygiene and when to contact a doctor.
The Centers for Disease Control and Prevention recommends an annual flu vaccine for everyone aged six months and older who has no contraindication. For the 2026–27 season, the CDC says its current recommendations remain in effect and advises people to get vaccinated by the end of October when possible.
Dr. Jeanne Marrazzo, identified by ABC News as chief executive of the Infectious Diseases Society of America, said vaccination is especially important for children with chronic conditions and those under five. The CDC’s latest count for the 2024–25 season is 298 flu-associated child deaths. Among eligible children whose vaccination status was known, about 89% were not fully vaccinated.
Depending on age and health, children may be eligible for an injectable vaccine or a nasal spray. The CDC says children aged two to four with asthma or recent wheezing should not receive the nasal spray. Parents should discuss vaccine choice with a pediatrician when a child has a chronic condition.
Marrazzo also advised families to encourage handwashing and covering coughs. If a child becomes ill, fluids and limiting contact with other household members can help. CDC-listed flu symptoms include fever, chills, cough, sore throat, a runny or stuffy nose, body aches, headache, fatigue and, in some cases, vomiting or diarrhea.
Parents should contact a doctor if they are concerned, particularly if the child is under one year old or has asthma, cancer, lung disease or requires dialysis. The information does not replace advice from a pediatrician.
