Hit Me With Your Best Shot: 4 Reasons to Consider Getting Your Flu Shot This Year

**By Christopher Baliga, MD**

The flu is a contagious disease caused by influenza viruses that infect the nose, throat and lungs, causing mild to severe illness and, in extreme cases, can lead to death. Fortunately, there is a way to mitigate both your own risk from the flu and the risk of those around you, too – enter the annual flu shot. These influenza viruses tend to mutate year-after-year, meaning that every flu season is different and warrants a new vaccine each year.

The CDC estimates that in the U.S., flu season can begin as early as October and as late as May, and is most rampant between December and February. The ideal time to get your flu shot is in the weeks leading up to the start of flu season but can still be effective if received later than this.

Whether we like it or not, flu season is right around the corner. Read on for four reasons why you should consider getting your flu shot this year.

It can lower your risk of contracting the flu

I’ll start with the obvious – getting your annual flu shot is your best defense against catching the dreaded flu as it allows your body to harbor and build up the necessary antibodies to protect against each new strain. According to the CDC, when the vaccine viruses are similar to the viruses going around, flu shots have proven to reduce the risk of flu-related doctor visits by 40-60%.

 It’s important to note that while the flu shot doesn’t guarantee full protection, it’s still worth getting.

It reduces the severity of flu-related illness

How your body responds to each flu shot varies from person to person. For example, it tends to be more effective for people under the age of 65, as older folks may develop less immunity after receiving it than their younger counterparts.

But, even if the shot doesn’t completely prevent the flu, it can still weaken the severity of illness if you do end up catching it. It can also lower your risk of developing serious complications that could eventually lead to hospitalization. And naturally, reducing the severity of flu-related illness can also lead to fewer hospitalizations on a macro level.

Getting vaccinated helps protect those around you, too

Receiving a flu shot allows you to play a role in protecting those around you who may be more vulnerable to serious flu-related illness, such as young children, older people and those with chronic medical conditions. It helps train your immune system to fight these nasty germs, which in turn diminishes your risk of transmitting them to those around you.

The flu is expected to have a nasty return post-COVID

Thanks to masks, social distancing and heightened hand hygiene across the U.S. amid COVID-19, other germs were kept at bay – including the flu. But, as these preventive measures begin to ease up, cold and flu viruses are expected to make a nasty return, making this year’s vaccine more important than ever before. Getting your flu vaccine at the same time as your COVID-19 vaccine? No problem – it is safe to get both.

Now that summer has come and gone, it’s time to shift attention to protecting ourselves, and those around us, from the flu’s return by receiving a flu shot. If you’re unsure of where to go for this, check out the HealthMap Vaccine Finder or talk to your doctor.
