The flu is a respiratory illness caused by a virus. It can cause mild to severe illness—and can even lead to death. The flu can cause severe illness in healthy children and adults. Flu is especially dangerous for those with chronic illnesses.
The best way to prevent flu is to talk to your doctor about getting a vaccine that will help protect you and your child. The vaccine is for everyone age 6 months and older and is safe for children. Everyone in your family should get vaccinated to protect children who are too young to get the vaccine.
