In short, yes - everyone should be vaccinated yearly.
For some particularly vulnerable groups, the influenza virus can be lethal, so getting your annual flu shot is the best way to protect not just yourself, but the people you know.
"It's recommended for everyone, but there are certain groups that are at much higher risk of complications and hospitalisation from the flu," says Dr Palmer. "That's those who are over 65, pregnant women, children aged between six months and five-years-old in most states, those who identify as Aboriginal or Torres Strait Islander aged over 15 years, and anyone with a chronic disease or compromised immune system. That covers a fair proportion of the population."
So if you are in one of these groups, or you come into contact with anyone in these groups, you need to get the flu shot.
"The message is very loud and clear: it's a safe, effective vaccine," says Dr Palmer.
There is a national immunisation program that offers free vaccines for the at-risk groups listed above, and any other member of the population can purchase it for a small fee through pharmacies or their GP.
