The flu vaccine is your best defense against seasonal flu. Everyone six months of age and older should get the flu vaccine. If you or a loved one has flu symptoms, learn the right way to treat your symptoms or care for someone in your home who has the flu. You should only go to the Emergency Department if you need emergency care – such as if you’re having difficulty breathing, are confused, dizzy or lightheaded, or having chest pain. If you have questions about the flu or any underlying medical problems, call your doctor for further instructions.
