Keeping up to date with vaccines, including the flu vaccine, can help build a stronger immune response and provide better protection against viruses.1  

Things you can do to support your immune system include:

  • Get enough sleep. While sleeping, your body produces and releases cytokines – a protein that targets infections.2
  • Exercise regularly. Physical activity prompts antibodies and white blood cells to travel throughout the body more quickly, ready to identify illnesses.3,4
  • Minimise stress. Over time, increased cortisol levels can have a negative effect on several parts of the body, including the immune system.5
  • Keep up to date with all vaccines. Vaccines are one of the simplest, most effective things you can do to help prevent and/or reduce the severity of a viral infection.
