  1. The first and most important step in preventing flu is to get a flu vaccination each year. All children over 6 month of age should be vaccinated against influenza.
  2. Vaccination is especially important for people at higher risk of serious influenza complications, and for people who live with or care for high risk individuals.
  3. CDC also recommends everyday preventive actions such as staying away from people who are sick, covering coughs and sneezes and frequent handwashing.
