Common Myths About the Flu Vaccine
The flu can cause a range of symptoms, from aches and pains to chills and fatigue, and it can leave people unwell for up to two weeks. In some cases, it can even be life-threatening. While the best way to prevent the flu is through a vaccine, many people still have misconceptions about its effectiveness and safety. Let’s explore some of the most common myths surrounding the flu vaccine.
Myth 1: The flu jab makes you sick
A popular myth is that the flu vaccine itself causes illness. According to Brenton Hart, Chief Pharmacist at TerryWhite Chemmart, this is not true. “The flu vaccine cannot give you the flu because it contains inactivated virus or viral components only. Mild side effects like soreness, fatigue, or low-grade fever are normal and short-lived. These symptoms show your immune system is responding, which is a good sign.”Myth 2: One flu vaccine will protect you for life
Influenza A and B are the most common types of the virus, but there are many different strains that change each year. “Flu viruses change constantly, so the vaccine is updated annually to match the most common strains,” says Brenton. “Immunity from last year’s vaccine fades over time, leaving you less protected. An annual vaccination ensures the best defence against severe illness and complications.”
Myth 3: Healthy adults don’t need a vaccine
While most healthy adults may recover well from the flu, it’s the very young, elderly, and those with chronic conditions who are more at risk of serious complications. However, that doesn’t mean healthy adults should skip the vaccine. Not only does it reduce the risk of getting the flu, but it can also make symptoms less severe. More importantly, the vaccine helps reduce the spread of the illness, protecting vulnerable individuals. “Healthy adults can still catch and spread flu, which puts babies, older adults, and people with chronic conditions at risk because they’re more likely to have a more severe case of the flu if they catch it,” says Brenton.Myth 4: The flu isn’t that serious – it’s just a cold
Many people confuse the flu with a common cold. While both are contagious respiratory illnesses, the flu typically has much more severe symptoms, such as a high fever, and can lead to serious complications. “Flu can cause serious complications, even in healthy people, including pneumonia and hospitalisation,” says Brenton. Colds are generally milder, and there is no vaccine for the common cold.Myth 5: The vaccine doesn’t work – I still got the flu
Each year, experts predict which strains of the flu are most likely to circulate. “Even when the match isn’t perfect, the vaccine still provides meaningful protection and lowers the chance of severe complications and hospital admission,” says Brenton. If you do get sick, symptoms are usually milder and you recover faster compared to being unvaccinated. It’s also possible that you caught a different virus altogether, such as RSV, adenovirus, or rhinovirus, which the flu vaccine does not protect against.

Flu Vaccinations – Your Questions Answered
Why do some people feel sick after getting the flu vaccination? Can it actually give you the flu?
It’s one of the most common things we hear, and the short answer is no, the flu vaccination cannot give you the flu as the virus in the shot is inactive. What you’re feeling is actually your immune system practising to fight the virus, which can sometimes result in a slightly sore arm or a mild, short-lived feeling of being “under the weather.” It’s actually a sign that your immune system is working and building that vital shield for the season ahead.
I rarely get sick. Is it really worth making an appointment?
Definitely. Staying healthy is about being proactive rather than reactive. While things like diet, exercise, sleep, and hydration are the cornerstone of good health, the vaccination is a vital extra shield. Even if you’re fit and active, the flu can knock you around for a week or more, leading to missed work or cancelled plans. By protecting yourself, you’re also protecting the people you interact with who might not be as resilient, like elderly neighbours, newborns, and young children, or colleagues with underlying health issues.
Why do I need a new vaccination every year?
Unfortunately, the flu is a bit of a shapeshifter. The dominant strains change from year to year, so the vaccine is updated annually to match the most current versions of the virus. Think of it like a software update for your immune system – you need this year’s version to protect against this year’s germs. Plus, your immunity naturally wanes over time, so that annual booster ensures your protection is at its peak just as the winter chill sets in.
