Flu season is just about here, and I'm sure you've seen some of its victims. Coming down with the flu is terrible -- no one likes achy muscles, a high temperature and an upset stomach. Luckily, advances in vaccinations have allowed scientists to develop new flu shots every year that are pretty darn effective. Yet, many people still avoid getting their flu shot because of common misconceptions that run rampant. I'm here today to explain some of these myths you've probably heard, and why they are ultimately not true.

Who should and who shouldn't get the flu shot?

The CDC recommends that everyone over six months old gets their flu shot, especially people at higher risk like the elderly, children under two years old, people who are pregnant and anyone with chronic conditions.

There are different types of flu shots that are approved for different ages, so the physician administering your vaccine will choose the right one for you. For example, the recombinant influenza vaccine is only approved for people over 18 years old. 

Without further ado, let's get into some different misconceptions that cause people to skip their flu shot and why they aren't true.

1. I got one last year so I don't need another

The flu shot is basically the same every year, right? Actually, it's not. Rite Aid's Chief Pharmacy Officer, Jocelyn Konrad, said that people should make sure they're getting a new flu shot every year: "Because flu viruses evolve so quickly, there are new vaccinations released every year to match the most common flu viruses expected during the upcoming season. Last season's vaccine may not protect you from this year's viruses." 

The body's immune response from vaccination wanes over time, so annual vaccination is your best defense against the flu. Even though last flu season might've felt like just yesterday, you should make sure to stop by your local pharmacy to renew your vaccination.

2. The flu shot will give me the flu

This one is another myth that causes people to skip their flu shot, but it's also not true.

"Some people report having mild reactions to flu vaccination, such as low-grade fever and aches, that are mistaken for the flu," Konrad told CNET, "but those symptoms aren't actually the flu."  

The CDC explains why. Flu shots are made in two ways: 

  • With inactive (dead) flu viruses that aren't infectious; or 
  • With one gene from a flu virus, as opposed to the whole virus. 

Inactive flu vaccines aren't infectious, and the single-gene vaccines produce an immune response but aren't strong enough to cause an infection. 

So, even if you feel mildly achy after a flu shot, it's light years better than spending a few days in bed immobile because you came down with the actual flu.

3. The flu shot will make me more susceptible to other respiratory diseases

One study from 2012 suggested that people who receive the influenza vaccination are at a greater risk for other diseases with symptoms like a runny nose and a sore throat. A lot of people heard about the preliminary finding, and word spread like wildfire that the connection was definitely true. Researchers were then prompted to delve deeper into the association, and numerous studies have since disproved the link.

The CDC states that medical professionals are unclear why the 2012 study suggested those results, but that it's not something to be concerned about whatsoever, and that it shouldn't deter you from getting your flu shot.

4. Getting the actual flu will make me immune

Some people might think that if a housemate is sick, they'll probably catch it anyway, and the virus will do a better job at making them immune for the next time the flu comes around.

The CDC reports that this is a bad decision -- getting the flu comes with the risks of dehydration, hospitalization and other health complications, even if you're a relatively healthy person before getting sick. It's far better to get the vaccine in advance than to wait for what you may think is inevitable.

5. I'm healthy, so I don't need a flu shot

I'll admit that this is an excuse I sometimes find myself using. I'm young and generally in good condition, so even if I come down with the flu, I'll only feel bad for a day or so, right?

It turns out that the CDC says that even healthy children and adults can risk hospitalization or severe complications from a bout of the flu. It's one of those things that you think will never happen to you until it does, so please join me in getting a flu shot this year to prevent this horrible possibility

6. The flu shot doesn't even work

It can be hard to believe in the power of the vaccination, especially when you or someone you know has still gotten sick after getting the shot.

While effectiveness varies from season to season, during times when the vaccine has matched the virus well, the CDC reports that the flu shot reduces the risk of having to visit the doctor with the illness by 40% to 60%.

Plus, it's not just the flu -- the vaccination works well in reducing hospitalizations for any flu-related conditions. In recent years the vaccine reduced children's chances of landing in the ICU unit by 74% and adults by 40%.

7. It's too far into flu season to get the shot

If you find yourself too busy to make it to the doctor's office for a flu shot until you're well into November, it's easy to just forget the vaccine till next year. You may think that flu season is almost over, so there's no point.

Although the CDC recommends getting a flu shot before the end of October, flu season can sometimes last until April of the next year. So, if you're sitting at the Thanksgiving dinner table thinking it's too late for a vaccine, you'll be better off getting the shot a few weeks late than not getting it at all.
