What Is New This Year

This year’s flu vaccine protects against three flu viruses. All three were updated from the 2025-2026 version, according to the Centers for Disease Control and Prevention (CDC).

One key change targets the H3N2 subclade K virus. That strain spread widely last season.

“It’s a brand-new vaccine this year,” said Dr. Stephen Thacker, a pediatric infectious diseases specialist, in an interview with Medical University of South Carolina (MUSC) Health.

Makers expect to supply up to 135 million doses for the United States this season.

135 millionFlu vaccine doses makers project for the United States this season, per the Centers for Disease Control and Prevention (CDC).

Who Should Get a Flu Shot

Flu vaccines are available for nearly everyone aged 6 months and older. Some people face a higher risk of serious illness.

The Centers for Disease Control and Prevention (CDC) explains who needs a flu vaccine.

Children under 5
Adults over 65
Pregnant women
People with diabetes, heart disease, kidney disease or asthma
People with weakened immune systems

If you live with or care for someone at high risk, getting vaccinated helps protect them too.

Quick tip. Wear a short-sleeved shirt to your appointment. It makes the shot quicker and easier.

When to Get Vaccinated

Dr. Thacker suggests getting vaccinated in mid-to-late October, and no later than November. Your body needs about two weeks to build protection.

Some areas see flu cases rise earlier. So check local health alerts for your state.

If you missed October, do not skip it. Getting the vaccine in November still offers protection through the peak winter months.

Types of Flu Vaccines

Several kinds of flu vaccines are available. Your doctor or pharmacist can help you choose.

Vaccine type	Who it is for	Notes
Standard flu shot	Most people 6 months and older	Most common option
Cell-based or recombinant	Many adults	Made without eggs
Nasal spray	Healthy people who prefer no needle	Not for high-risk groups
Options for older adults	Adults 65 and older	Ask about stronger vaccines made for this age

About 27 percent of this year’s supply is made without eggs. Also, nearly all of the supply has no thimerosal preservative.

Good to know. You can usually get a flu shot and other routine vaccines at the same visit. Ask your pharmacist.

Where to Get a Flu Shot

Flu shots are easy to find. You can usually get one at a pharmacy, your doctor’s office or a local health clinic.

Offers can change and many vary by location. Confirm before you go.

Find a nearby clinic on Vaccines.gov.

Many health plans cover the flu shot at no cost. Check with your insurance or pharmacy before you go.

When to Get Help

Get medical care right away if you or a loved one has any of these flu warning signs.

Trouble breathing or shortness of breath
Ongoing pain or pressure in the chest or belly
Ongoing dizziness or confusion
Seizures
Fever or cough that gets better, then returns or gets worse

These warning signs come from the Centers for Disease Control and Prevention (CDC).

Flu or Cold? How to Tell the Difference

Flu and colds share many symptoms, so they are easy to mix up. However, flu usually hits harder and faster.

The Centers for Disease Control and Prevention (CDC) compares the two side by side.

Sign	Cold	Flu
How it starts	Slowly	Suddenly
Fever	Rare	Common
Body aches	Slight	Common and often strong
Tiredness	Mild	Can be extreme
Stuffy nose	Common	Sometimes

Only a test can confirm the flu. Call your doctor if you are not sure, especially if you are in a high-risk group.

Can You Get a Flu Shot With Other Vaccines?

Yes, in most cases. You can usually get a flu shot at the same visit as other recommended vaccines.

The Centers for Disease Control and Prevention (CDC) explains how getting vaccines together works. It saves you an extra trip.

Ask your pharmacist or doctor which vaccines you are due for this season. They can check your records.

Flu Shots and Egg Allergies

Many people worry about eggs in flu vaccines. The good news is that people with egg allergies can still get a flu vaccine.

The Centers for Disease Control and Prevention (CDC) shares guidance for people with egg allergies. Some vaccines are made without eggs at all.

Tell the person giving your shot about any allergies. They will help you choose the right option.

Common Flu Shot Myths

Myths can stop people from getting protected. Here are a few you may hear.

Myth One. The Flu Shot Gives You the Flu

It cannot. The shot does not contain a live virus that can cause the flu. Some people feel achy for a day, which is a normal immune response.

Myth Two. Healthy People Do Not Need It

Healthy people can still get very sick from the flu. They can also pass it to babies, older relatives and people with health problems.

Myth Three. One Shot Lasts for Years

Flu viruses change, and protection fades over time. That is why a new shot is recommended every season.

The Centers for Disease Control and Prevention (CDC) answers more common questions about flu vaccines.

Everyday Habits That Help Prevent Flu

A flu shot is the best first step. Healthy habits add another layer of protection.

Wash your hands often with soap and water.
Cover coughs and sneezes with a tissue or your elbow.
Avoid touching your eyes, nose and mouth.
Stay home when you feel sick.
Clean phones, doorknobs and other surfaces people touch often.

The Centers for Disease Control and Prevention (CDC) lists more healthy habits to prevent flu.

What to Do If You Get the Flu

Most healthy people get better at home. Rest, drink plenty of fluids and stay away from others while you are sick.

Call a doctor early if you are in a high-risk group. Prescription antiviral medicines work best when started soon after symptoms begin.

The Centers for Disease Control and Prevention (CDC) explains what to do if you get sick.

Traveling During Flu Season

Holiday travel brings crowds, which makes it easier for germs to spread. Plan ahead if you have a trip coming up.

Get your flu shot at least two weeks before you travel. That gives your body time to build protection.

Pack hand sanitizer and tissues in your carry-on. Wash your hands before eating, especially at airports.

The Centers for Disease Control and Prevention (CDC) shares flu prevention tips for travelers.
