Story at-a-glance

• Flu and flu-like illnesses are caused by viruses that can produce millions of copies within your cells
• As long as your immune system can stay one step ahead of the virus, you’ll feel better again quickly… and in some cases may not even know you were ‘sick’
• Strategies that support your immune system health will help you to ward off all types of viruses, whereas a flu vaccine will only partially protect you from the 3-4 influenza viruses it contains
• Healthy eating, exercise, sleep, stress and vitamin D levels are all factors that should be addressed to keep you well this flu season
