The American Academy of Pediatrics (AAP) says every child 6 months and older without a medical reason to skip it should get a flu vaccine for kids this season, and children who need two doses should ideally finish by the end of October. With about two weeks left in that window, this is the month to book the appointment.
This guide turns the AAP’s 2026-27 policy statement and Johns Hopkins Medicine’s fall vaccine guidance into a checklist for parents. It is general information, not medical advice. Your pediatrician knows your child’s history and should make the final call.
Who Should Get a Flu Vaccine for Kids This Year?
According to Contemporary Pediatrics, which reported on the AAP policy statement published in Pediatrics in 2026, the AAP recommends annual influenza vaccination for all children 6 months and older who do not have contraindications. In plain terms, that means nearly every child, every year.
Children under 6 months cannot get the shot. The usual way to protect those babies is to vaccinate the people around them, including parents, siblings and caregivers.
If your child has a history of a severe reaction to a vaccine or has a medical condition that complicates vaccination, ask your pediatrician before the visit. That conversation is what “without contraindications” refers to.
One Dose or Two? A Quick Guide by Age
Johns Hopkins Medicine says children 6 months to 8 years need two doses if they have never been vaccinated, if their history is unknown, or if they were not vaccinated on the recommended schedule. Children age 9 and older need one dose.
| Situation | Doses this season |
|---|---|
| Ages 6 months to 8 years, never vaccinated | Two |
| Ages 6 months to 8 years, history unknown | Two |
| Ages 6 months to 8 years, not vaccinated on the recommended schedule | Two |
| Age 9 and older | One |
The source material does not spell out the exact spacing between the two doses, so ask your pediatrician for the date of the second appointment when you book the first. According to the AAP, the two doses do not have to be the same brand.
Why the End of October Matters
The AAP advises vaccinating as soon as vaccine is available. For children who need two doses, the goal is to complete both by the end of October, which is why the first appointment should not wait.
Johns Hopkins notes that flu season often peaks from December through February and can run as late as May. A shot given later is still useful, but earlier protection lines up better with the busiest months.
Local signals suggest the season may not be waiting. Our report on the early flu season and the jump in emergency room visits in King County covers why experts are urging families to act now.
Which Flu Vaccine for Kids: Shot, Nasal Spray or a Specific Brand?
All 2026-27 flu vaccines in the United States are trivalent, according to the AAP. Afluria is no longer available. Per Johns Hopkins, the vaccines protect against two influenza A viruses and one influenza B/Victoria virus.
The AAP has no preference among egg-based, cell culture-based, recombinant or live attenuated vaccines when they are appropriate for the child’s age and health. Its guidance is direct: do not delay vaccination to wait for a specific product.
Johns Hopkins says a nasal spray is an option for people ages 2 to 49 who are not pregnant and have no underlying conditions. For a healthy school-age child, that can be a good choice for a needle-averse kid, but ask which options your clinic stocks.
Side Effects and the Febrile Seizure Question
Most parents want to know what a flu vaccine for kids might do beyond a sore arm. The sources supplied for this article focus on one specific, uncommon risk, so we will cover it plainly.
The AAP notes a small increased risk of febrile seizures on the day after standard-dose vaccination in children 6 months to 4 years. The estimated excess risk is about 1 per 22,624 doses of trivalent vaccine, and about 1 per 47,170 doses of quadrivalent vaccine. The AAP says this does not change its overall assessment that the benefits outweigh the risks.
Common, mild reactions such as soreness are not detailed in our sources, so check the information sheet your clinic provides. Call your pediatrician if you have questions after the visit, and seek emergency care for any serious symptom.
Can Kids Get the Flu and COVID Vaccines Together?
Johns Hopkins says flu and COVID vaccines can usually be given at the same visit. That can save a trip, which matters when you are juggling school and work schedules.
COVID eligibility and insurance rules differ by age and risk group. See our explainer on who can get the 2026-2027 COVID vaccine and what it costs. If you have an infant, our guide to RSV in babies and how to protect a newborn this fall covers the other respiratory threat of the season.
Flu Antivirals Explained for Parents
Vaccination is the first line of defense, but the AAP also updated its guidance on antiviral medicine. Oseltamivir is the preferred drug for both influenza A and B.
The AAP recommends early treatment for children who:
- are hospitalized with suspected or confirmed flu;
- have severe, complicated or progressive illness;
- are under 5 years old or otherwise at high risk.
These recommendations apply regardless of vaccination status or how long symptoms have lasted. For healthy children treated as outpatients, treatment may be considered if it can start within 48 hours of onset, or when household contacts are high-risk.
Chemoprophylaxis, meaning medicine given to prevent illness after exposure, also favors oseltamivir. It is generally not recommended for infants under 3 months unless the situation is critical. Only a clinician can decide whether any of this applies to your child.
Parent Checklist: Flu Vaccine for Kids in Five Steps
- Confirm age and history. Under 9 and not fully vaccinated before? Plan for two doses.
- Book now. Aim to finish a two-dose series by the end of October.
- Take what is available. The AAP says not to wait for a particular brand or type.
- Ask about pairing visits. Flu and COVID shots can usually be given together.
- Know your sick-day plan. If your child gets sick and is high risk or under 5, call early, since antivirals work best when started promptly.
Flu Vaccine for Kids: Quick FAQ
Is the flu vaccine for kids recommended every year?
Yes. The AAP recommends annual vaccination for all children 6 months and older without contraindications.
Does my child need two doses?
If your child is 6 months to 8 years and was never vaccinated, has an unknown history, or was not vaccinated on schedule, Johns Hopkins says two doses are needed. At 9 or older, one dose is enough.
Do both doses need to be the same brand?
No. The AAP says the two doses need not be the same brand.
Is the nasal spray allowed?
For ages 2 to 49 who are not pregnant and have no underlying conditions, Johns Hopkins lists it as an option.
What to Ask at the Appointment
A little preparation makes the visit faster. Bring your child’s vaccine record if you have it, since an unknown history means two doses for children under 9. Write down any past reactions to vaccines, and mention any medical conditions.
It also helps to ask three questions. Which flu vaccine for kids does the clinic stock this week? Can the COVID vaccine be given at the same visit? When should the second dose happen, if one is needed? Clear answers let you plan the whole season in one conversation.
Families with several children should check each child separately. A 10-year-old and a 6-year-old in the same household may need different numbers of doses, and a toddler in the 6 month to 4 year range falls into the group where the febrile seizure note applies.
Finally, remember that getting a flu vaccine for kids is also about the people around them. Babies under 6 months cannot be vaccinated, so a protected household is part of keeping them safe.
The Bottom Line
The takeaway is simple: check your child’s age and vaccine history today, then schedule the appointment this week so a two-dose series can finish by October 31. For the latest national guidance, check cdc.gov and aap.org, and read the underlying reports from Contemporary Pediatrics and Johns Hopkins Medicine.
