Flu shot season tends to sneak up on busy families, right as school schedules, sports, and fall activities are in full swing. The question we hear most from parents is when their child should actually get vaccinated. Pediatricians recommend September or October, with the goal of finishing by the end of October, so protection has time to build before flu activity typically rises in Northern Colorado. This guide covers exactly when to vaccinate, how many doses your child needs, the safety questions parents ask most, and what still helps alongside a flu shot to keep your family healthy this season.

When Should Kids Get a Flu Shot?
The Centers for Disease Control and Prevention recommends that everyone 6 months and older get a pediatric flu vaccine every year, completed by the end of October whenever possible. Protection builds over about two weeks, and flu activity in Colorado tends to pick up through late fall and winter, so hitting that window means your child is covered before exposure really increases.
If October has already come and gone, don’t worry. Flu season can last into early spring, so a late vaccination is still far better than skipping it altogether.
What’s the Flu Shot Schedule for Kids by Age?
Once the timing makes sense, the next question is usually how many doses your child actually needs, since that comes down to vaccination history more than age.
Every child 6 months and older can get an annual flu vaccine, and most only need one dose per year. The exception is young children, typically under age 9, who are getting their first flu vaccine ever, or who only received one dose in a previous season. For them, two doses spaced at least four weeks apart help build full protection. After that, children only need one dose per season going forward.
Our Express Flu Clinics make it easy to get your child vaccinated by appointment, and our immunization schedule page lays out the full recommended vaccine timeline for every age and stage.
What Flu Shot Safety Questions Do Parents Ask?
Once the schedule makes sense, a few practical questions tend to come up every fall. Here’s what we hear most often from families.
Can my child get a flu shot at the same visit as other vaccines?
In most cases, yes. A flu shot can typically be given at the same appointment as routine childhood vaccines, the COVID vaccine, and, for eligible infants, the RSV antibody. Ask your provider about your child’s specific situation.
Another question we hear just as often involves egg allergies, since that used to carry more restrictions than it does now.
Can kids with an egg allergy get a flu shot?
Yes. Current guidance treats egg allergy on its own as no reason to avoid or delay a flu vaccine. Kids with an egg allergy can receive any age appropriate flu vaccine using the same routine precautions as any other vaccine.
And for the youngest kids in the house, the timing looks a little different.
Can babies get a flu shot?
Children can start the flu vaccine at 6 months old. Babies younger than 6 months are too young to be vaccinated themselves, so the best way to protect them is making sure everyone around them, parents, siblings, and caregivers, is vaccinated too.
What Are the Most Common Flu Shot Myths?
Once the logistics are settled, it helps to clear up a few things that just aren’t true anymore, since a lot of flu shot hesitation traces back to outdated information.
Does the flu shot give kids the flu?
No. Flu vaccines use either an inactivated virus or no live virus at all, so they cannot cause flu illness. Mild soreness, tiredness, or a low grade fever afterward is usually a sign the immune system is building protection.
That mix up feeds a related myth, the idea that only certain kids really need the shot.
Do healthy kids really need a flu shot?
Yes. The CDC recommends annual vaccination for everyone 6 months and older, including healthy children, since flu can still cause serious illness even in kids with no underlying conditions.
Even families who vaccinate every year sometimes wonder if it’s worth it if their child could still catch the flu anyway.
If my child is vaccinated, can they still get sick?
It’s possible, since no vaccine is 100 percent effective. Vaccinated children who do catch the flu typically have milder symptoms and a lower risk of hospitalization.
And for families who feel like they’ve already missed their window, this last one matters most.
Is it too late to vaccinate after November?
Not usually. Flu season often continues into early spring, so a vaccine given in November, December, or later can still provide meaningful protection.
Why Does Vaccinating Early Matter?
With the logistics and the myths out of the way, here’s the real case for not waiting.
Waiting until flu is already going around means your child spends the early weeks of the season without protection. Vaccinating in September, ahead of the October deadline, gives the immune system roughly two weeks to build a response before exposure typically increases.
Early vaccination also helps you avoid the scheduling crunch that hits later in the season, once flu activity rises and appointment slots fill up quickly. Pairing a flu shot with an already scheduled well care visit is often an easy way to stay ahead of it, or you can book directly through our Express Flu Clinics for a quick, dedicated appointment.
How Does Flu Season Timing Work in Northern Colorado?
That timing advice isn’t just a national guideline. It plays out close to home too.
Flu activity in Colorado generally follows the same pattern the CDC tracks nationally. Cases typically start rising in late fall, peak sometime between December and February, and can continue into early spring.
For Northern Colorado families, that timing means a flu shot by the end of October has time to take effect before kids head back into crowded classrooms and holiday gatherings, both common places for flu to spread.
What Other Ways Can We Protect Our Family This Flu Season?
A flu shot does most of the heavy lifting, but a few everyday habits round out the picture.
Encourage your child to avoid touching their eyes, nose, and mouth, since that’s one of the easiest ways germs spread from a contaminated surface. Regular handwashing with soap and water for at least 20 seconds removes germs before they have a chance to spread. Good sleep, balanced nutrition, and manageable stress all support a stronger immune system heading into flu season. Flu viruses can also survive on hard surfaces for up to 48 hours, so disinfecting frequently touched areas at home and at work cuts down on exposure between family members.
What Should We Do If Flu Symptoms Appear?
Even with every precaution in place, flu sometimes still finds its way into a household. Here’s what to do if it does.
If your child develops fever, chills, muscle aches, cough, congestion, a runny nose, headaches, or fatigue, contact your provider promptly at 970.482.2515. Every child can present a little differently, so a quick call helps us figure out the right next step for your family.

Frequently Asked Questions
Does insurance cover my child's flu shot?
Most insurance plans cover the flu vaccine as a preventive service with little or no out of pocket cost, since it falls under routine childhood immunizations. Coverage can vary by plan, so it’s worth a quick call to your insurance provider, or ask our front desk, to confirm what your plan covers.
How long does protection from a flu shot last?
Protection generally lasts through one flu season, which is why the vaccine is recommended every year rather than just once. The viruses causing flu also change from year to year, so each season’s vaccine is updated to match.
Does the flu shot protect against the stomach bug people call the stomach flu?
The flu shot only protects against influenza, a respiratory illness. The stomach bug often called the stomach flu is usually caused by a completely different virus, like norovirus, and the flu vaccine does not prevent it.
If my child already had the flu this season, do they still need the vaccine?
Flu vaccines protect against several different flu strains circulating each season, so a shot can still help protect against strains your child hasn’t been exposed to yet.
