Every fall, a few things are almost guaranteed here in South Arkansas. Football season gets underway, the weather finally starts cooling off, and before long, we’re making plans for Thanksgiving and Christmas. Unfortunately, there’s another familiar visitor preparing to make its annual appearance: influenza, better known as the flu.
And unlike most holiday visitors, the flu tends to show up uninvited.
Around this time of year, I start hearing some familiar questions from patients: “Doc, is it time for my flu shot?” “Didn’t I just get one last year?” And perhaps the most common question, “Can the flu shot actually give me the flu?”
With October upon us, it’s a good time to address these questions and discuss why influenza vaccination remains an important part of preventive healthcare.
The Flu Is More Than Just a Bad Cold
Unlike the common cold, influenza often develops suddenly. You may feel perfectly fine one afternoon and wake up the next morning with fever, chills, body aches, coughing, and overwhelming fatigue that can leave you feeling completely wiped out for days.
For many otherwise healthy adults, the flu means several miserable days at home. But for some people, especially young children, older adults, pregnant women, and those with chronic medical conditions, influenza carries a much higher risk of serious complications, including pneumonia, hospitalization, and even death.
As a physician, I’ve seen firsthand how quickly influenza can become serious, particularly for those in these higher-risk groups.
Timing Is Everything: Why October Is a Great Time
The Centers for Disease Control and Prevention (CDC) recommends that most people receive their annual influenza vaccine during September or October, ideally by the end of October.
It takes approximately two weeks after vaccination for your immune system to develop protective antibodies. Getting vaccinated early gives your body a head start before flu activity increases.
And if October slips by, don’t worry. Influenza can circulate well into the spring, so getting vaccinated later in the season is still worthwhile.
“But Doc, I Got My Flu Shot Last Year!”
This is a common misconception.
Influenza viruses are constantly changing. Even though your immune system may recognize strains from previous years, the virus continues to evolve, making it more difficult for your body’s defenses to recognize new strains.
That’s why scientists review and update influenza vaccines each year. In fact, all three components of the 2026–2027 influenza vaccine have been updated compared to last year’s vaccine.
Additionally, protection from vaccination decreases over time.
Simply put, last year’s flu shot is not a substitute for this year’s vaccine.
“I Got the Flu Shot and Still Got the Flu!”
Yes, that can happen. The influenza vaccine is not 100 percent effective, and receiving it doesn’t guarantee you won’t become infected.
However, vaccination can reduce your chances of getting influenza and, importantly, lower your risk of severe illness and hospitalization.
I often compare it to wearing a seat belt. It doesn’t guarantee you won’t be involved in an accident, but it can make an enormous difference in how badly you’re injured.
The flu vaccine works in much the same way. It’s about reducing your risk, particularly when it comes to serious complications.
Can the Flu Shot Actually Give You the Flu?
Let’s clear up one of the most common misconceptions.
No, the injectable influenza vaccine cannot give you influenza.
Some people experience temporary soreness at the injection site, fatigue, headache, or a low-grade fever after vaccination. These symptoms are generally mild and reflect your body’s immune response.
If someone develops influenza shortly after vaccination, they may have already been exposed to the virus or become infected before the vaccine had time to provide protection.
The timing may be unfortunate, but the vaccine itself did not cause the infection.
Who Needs the Flu Vaccine?
The short answer? Almost everybody.
The CDC recommends annual influenza vaccination for everyone 6 months of age and older, with rare exceptions.
Vaccination is particularly important for older adults, young children, pregnant women, and patients with conditions such as diabetes, asthma, COPD, heart disease, or weakened immune systems.
Adults 65 and older should ask about enhanced influenza vaccines recommended for their age group. Some young children may also need two doses, depending on their vaccination history.
And remember, babies younger than 6 months cannot receive the vaccine, making vaccination especially important for parents, grandparents, and other caregivers.
Protecting yourself against influenza can also help protect those around you, especially people who are more vulnerable to serious illness.
The Bottom Line
Between work, school activities, football games, and holiday gatherings, nobody wants to spend a week in bed with the flu.
While the influenza vaccine isn’t perfect, it’s one of the best tools we have to reduce our risk of influenza and its potentially serious complications.
If you haven’t received your flu vaccine yet, October is an excellent time to roll up your sleeve. Let this article be your reminder to get your flu shot—not a friend or family member’s flu diagnosis.
