Flu Shot: When to Get It, Where to Go, and Why It Still Matters

Every year around late summer and early fall, the question comes up: should I bother getting a flu shot this year? And every year, the answer from every major health organization is the same: yes, for most people, the benefits clearly outweigh the risks.

But timing, eligibility, and location all matter. Here’s what you need to know for the 2026 flu season.

Why the flu shot still matters

Influenza is not just a bad cold. Each year in the United States, flu causes millions of illnesses, hundreds of thousands of hospitalizations, and tens of thousands of deaths, even in years when the vaccine is a reasonably good match for the circulating strains.

For healthy adults, the flu is usually miserable but manageable. For children under 5, adults over 65, pregnant women, and people with chronic conditions like diabetes, heart disease, asthma, or weakened immune systems, it can be genuinely dangerous.

Vaccination doesn’t just protect you, it reduces how much virus you can spread to the people around you who are more vulnerable.

When is the best time to get a flu shot?

September through October is the sweet spot for most people. The flu season typically peaks between December and February, and protection develops within about two weeks of vaccination. Getting your shot in September or October means you’re protected before the peak hits.

• Getting vaccinated too early (July/August) may mean protection wanes slightly by February.
• Getting vaccinated late (November or later) is better than not at all, it’s never too late during flu season.

Children receiving a flu vaccine for the first time need two doses given at least four weeks apart. Plan accordingly to have both doses completed by the end of October.

Who should get a flu shot?

The CDC recommends annual flu vaccination for everyone 6 months and older, with rare exceptions. It’s especially important for:

• Children 6 months through 5 years old
• Adults 65 and older (who may benefit from high-dose formulations)
• Pregnant women, the shot is safe during any trimester and also protects the newborn
• People with chronic medical conditions (asthma, diabetes, heart disease, kidney disease, HIV, obesity)
• Healthcare workers
• Caregivers or household members of high-risk individuals

Who should not get the flu shot (or should talk to their doctor first)

Most people can and should get the flu shot. But you should check with your doctor first if:

• You have a severe, life-threatening allergy to any component of the flu vaccine
• You’ve had a severe reaction to a flu vaccine in the past
• You’ve been diagnosed with Guillain-Barré Syndrome after a flu vaccine previously

If you have a mild illness or low-grade fever, it’s generally fine to still get vaccinated, just ask when you come in.

Nasal spray vs injection

For children aged 2–17 and healthy non-pregnant adults aged 49 and younger, a nasal spray version of the flu vaccine (FluMist) is available as an alternative to the injection. It’s just as effective for most people in that age range and some kids prefer it over a shot.

Ask your provider which option is right for your child.

What to expect after the flu shot

The flu shot cannot give you influenza, it contains inactivated (killed) viruses that cannot cause illness. However, some people experience mild temporary side effects as the immune system responds:

• Soreness, redness, or mild swelling at the injection site
• Mild fever
• Headache
• Muscle aches
• Fatigue

These side effects typically resolve within 1–2 days and are a sign that your immune system is responding to the vaccine.

Does the flu shot always work?

The flu shot’s effectiveness varies by year depending on how well the vaccine’s strains match the circulating viruses. In well-matched years, the vaccine reduces flu illness by 40–60%. In less matched years, protection is lower, but even partial protection can reduce the severity of illness if you do get sick.

Getting vaccinated also reduces your risk of being hospitalized from flu, even in seasons when the match isn’t perfect.

How to protect yourself beyond the shot

Vaccination is the most important protective measure, but it combines well with:

• Washing hands frequently with soap and water for at least 20 seconds
• Avoiding touching your face
• Staying home when you’re sick (and keeping sick children home from school)
• Disinfecting frequently-touched surfaces during cold and flu season
• Maintaining good sleep, hydration, and nutrition to support your immune system
