Do I Really Need the Flu Shot Every Year?

If you’re healthy, it might feel like you can skip the flu shot. After all, you’re not likely to get seriously ill… right? But what if that quick appointment could protect you—and everyone around you—for the entire season? 

Flu shots are easy, safe, and more important than you think. Here’s why doctors recommend them every year, and how you can get yours through Denova’s primary care services. 

What Is the Flu Shot? 

The flu shot is a seasonal vaccine that helps your body build protection against the most common strains of influenza expected to circulate that year. Public health experts—including those at the CDC—study flu trends worldwide each season to guide the vaccine’s formulation. 

It works by prompting your immune system to create antibodies that fight off the flu. Full protection kicks in about two weeks after the shot. The CDC recommends getting vaccinated by September or October for the best coverage, but later is still better than not at all. 

Why You Need a Flu Shot Every Year 

Flu viruses change every year. That means last year’s vaccine likely won’t protect you from this year’s strains. On top of that, the effectiveness of each vaccine fades over time—usually after about six months. 

That’s why health experts like the CDC and Mayo Clinic recommend everyone aged 6 months and older get a flu shot each year. It’s a simple, science-backed way to reduce your risk of getting seriously sick. 

Even Healthy People Need It 

You might feel fine today, but the flu can affect anyone—and if you get it, you could unknowingly pass it to others. That includes infants, older adults, people with compromised immune systems, and those living with chronic conditions. 

Even if you don’t end up in the hospital, the flu can still knock you out for days. Getting vaccinated reduces the chance of severe illness and shortens recovery time if you do catch it. It also supports community protection by reducing transmission overall. 

What Are the Benefits? 

Annual flu shots are shown to reduce doctor visits and hospitalizations, especially among people with underlying health issues. Pregnant individuals who get vaccinated also pass on some protection to their babies. And if you’re exposed to viruses like COVID-19, having flu protection lowers your risk of severe complications from dual infections. 

Overall, the flu shot helps you recover more quickly if you do get sick and can make your illness much milder. 

At Denova, we know your time and health matter. That’s why we offer same-day appointments, Medicaid coverage, and providers who listen. Our goal is simple: keep you healthy—before you ever get sick. 

Are Flu Shots Safe? 

Yes. Flu vaccines are FDA-approved, tested annually, and monitored closely for safety. Most people experience only mild side effects—like a sore arm or slight fatigue—that resolve within a day or two. 

Serious allergic reactions are extremely rare. You can also safely get a flu shot alongside other vaccines, including COVID-19 boosters.
