4. Get a flu shot
The annual flu shot is a safe and effective way to protect yourself and loved ones from influenza, which makes its rounds each year.
This shot essentially gives your immune system a head start on the annual flu virus. It injects dead flu cells into your body, so that your immune system starts creating antibodies to fight off the virus (as the cells are already dead, they cannot hurt you).
Should you catch the real thing at any point, your immune system has already created an army of antibodies to fight it off, so you should only have mild symptoms. This also means that should you catch the flu and another virus around the same time, your immune system can focus on the other virus, rather than battling both at once.
Here in Australia, the National Immunisation Program (NIP) offers the flu shot for free for certain groups, including over 65s, pregnant women, children aged 6 months to five years, Aboriginal people, and some with medical conditions. Costs for everyone else varies, but is not prohibitive, and should be weighed against the costs of catching the flu.
