5 flu myths debunked

As flu season approaches, it's essential to be informed about the flu and the flu vaccine. Unfortunately, many myths and misconceptions about the flu and the flu vaccine can prevent people from getting vaccinated. This post will explore five of the most common myths about the flu vaccine.

Myth 1: I got the flu from my flu vaccination

This is a common myth, but it’s untrue. The influenza vaccine contains an inactivated virus which can’t give you the flu. If you experience any side effects, including a slight fever or muscle aches, this is a reaction from your immune system to the vaccine 1.

The side effects should go away in a day or two, but if they don’t, please visit your doctor or local Blooms The Chemist Pharmacist for more information.

Myth 2: I was outside when it was cold, I got the flu

You can’t catch the flu from being out in the cold without a coat, with wet hair or sitting near an open window. These are just old wives tales that you were told to help you stay warm in Winter.

The only way to get the flu is by being exposed to the influenza virus 1.

Myth 3: I got my flu shot, so now I can’t get the flu

Just because you’ve had the flu vaccination doesn’t mean you can’t get the flu.

While vaccination is the best prevention 1, you must take precautions to stop the spread, including washing your hands frequently and avoiding contact with people with the flu.

After you get vaccinated, it’s still possible that you may get the flu, but the symptoms will usually be much milder.

Myth 4: I don’t feel sick, so I can’t spread the flu

Just because you don’t feel sick or have outward symptoms of the flu, including sneezing, coughing, or muscle aches, doesn’t mean you don’t have the flu.

Around 20 to 30% of people carrying the influenza virus have no symptoms 2, which is how it spreads easily from person to person.

Myth 5: I only need to get the flu vaccine once

This isn’t true either, believe it or not! You need to get the flu vaccination yearly as the influenza virus mutates yearly, and the previous flu vaccine can’t protect you from the newer strains1.

Vaccination every year is essential to ensure immunity to the most common strains of the new influenza virus.
