As crisp fall weather rolls in, there’s another change in the air. The flu.
Influenza causes millions of illnesses in the United States every year. But annual flu shots also help prevent millions from getting sick – and that’s a fact.
According to the Centers for Disease Control and Prevention, 2018-2019 flu vaccinations helped prevent an estimated 4.4 million illnesses – plus thousands of hospitalizations and deaths.
But there’s a lot of misinformation floating around out there. New and scary flu shot myths spread quickly, just like the flu does.
That’s why I care so deeply about separating flu shot myth from flu shot fact. I think we can all agree keeping ourselves – and our community – healthy during the long flu season should be a top priority. And getting your flu shot is the best way to make that happen.
So, let’s take a look at some of the most common flu myths versus the facts you need to know.
Myth #1: You can get the flu from the flu shot
Fact: The flu shot cannot give you the flu. The virus strain delivered in the vaccine is no longer active.
For some, the flu shot does come with mild side effects which can easily be mistaken for early flu-like symptoms. The most common include mild soreness, tenderness or a bit of swelling at the injection site. You may also run a small fever, or experience slight headaches or muscle aches.
On the other hand, many experience no side effects at all! Plus, a day or two of mild discomfort simply doesn’t compare to what you can experience with a full bout of the flu. Flu symptom onset is fast and often involves fever, chills, extreme fatigue, muscle aches and more for several days.
Myth #2: Waiting until winter for a flu shot is safer
Fact: While peak flu season is between December and February, you can get sick as early as October. Some believe that getting vaccinated later will protect them longer, which simply is false. This also leaves you exposed for weeks, or months while the virus is floating around.
Also, an annual flu shot helps your body build immunity for the types of influenza viruses that research indicates will be the most common that season. But immunity isn’t built as soon as you get the shot. How long does it take for the flu shot to take effect? Two weeks – which is another reason to schedule your flu shot early.
Flu shots are typically available by early September – well before the traditional flu season begins. But it’s never too late to get your shot – even in January. Influenza season can often last well into May. Late protection is better than no protection at all!
Myth #3: I don’t need the vaccine, I never get the flu
Fact: Unfortunately, a flu-free history does not guarantee a flu-free future. Flu strains evolve and change over time, which means you are at risk every year you avoid getting vaccinated. In addition, when you skip your shot you can still carry and pass flu germs to others.
Influenza symptoms can leave us stuck in bed for days using up valuable vacation time. I always ask patients, why not save up those days for a sunny vacation instead?
Myth #4: Flu shots don’t work
Fact: The flu vaccine can significantly reduce your risk of catching the flu.
In previous years when the vaccine matched circulating strains, the CDC reports that getting vaccinated reduced the chance of catching the flu by up to 60%.
Flu vaccination also significantly reduces the risk of flu-related hospitalization for the elderly, working age adults, and especially among children. For kids, it could even be a life-saver. A 2017 study showed that flu vaccinations reduce a child’s risks of dying from the flu.
Flu shots are important for pregnant women too. Since pregnancy affects your immune system, it can make you more susceptible to the flu. Getting a flu shot while you’re pregnant is safe for both mom and baby. Plus it can help protect the baby after they’re born until they can have their first flu shot.
When more people choose to vaccinate, doctors and CDC researchers are better equipped to pinpoint flu strains, keep rates of hospitalization down, and keep you and your family protected. Also, the science of vaccinations improves every year, and so do your odds of staying healthy with a flu shot.
Myth #5: Catching the flu builds your immunity more than the vaccine
Fact: Having heard that the flu shot doesn’t always work, some are led to believe that getting the flu will boost your immunity more than the flu shot.
There’s no truth to this claim. And sitting around waiting for the flu to strike is certainly not a good idea.
The flu can get serious fast, especially in children and older adults. But it also carries risks of complications for healthy people. Getting vaccinated is much safer, and comes with the same immunity benefits.
While protecting you, the flu shot also protects loved ones around you from getting sick. Once your body builds immunity – which takes two weeks – you can’t pass flu germs to anyone else. Now that’s something you can feel good about.
Be a flu fighter by getting your annual flu shot
There are a lot of reasons to get a flu shot. It’s fast. It’s easy. It’s almost always free. But maybe one of the most important reasons is that it can significantly reduce your risk of getting the flu and passing it to others. And this helps you, your family and community stay healthy, happy and productive.
