Flu season is arriving, and the 2026-27 flu vaccine guidance is clear on one point: the annual shot is still recommended for most people. The CDC has issued interim clinical considerations for the season, and the American Academy of Pediatrics has published its own guidance for children. If you have not been vaccinated yet, the best timing window is now. This article is general health information, not medical advice, so talk with your clinician about your situation.
Flu Vaccine 2026-27: What the CDC Says
According to a summary from AHCA/NCAL published Sept. 8, 2026, the CDC released interim clinical considerations for seasonal flu vaccination. The July 2025 immunization schedule recommendations remain in effect for the 2026-27 season, and the agency states that “routine annual flu vaccination remains recommended.”
In practical terms, most people should plan to get a flu shot this year. People at higher risk of serious flu complications are especially encouraged to be vaccinated, as are people who live with or care for high-risk individuals, including healthcare personnel.
When Is the Best Time to Get a Flu Shot?
For most people, the CDC says vaccination ideally takes place in September or October. That window is closing, but it does not mean you have missed your chance. Vaccination should continue throughout the season for as long as flu viruses are circulating. If you are reading this at the end of October, getting your shot this week or next is still a sensible plan.
Which Flu Vaccine Should Adults 65 and Older Get?
Adults 65 and older should preferentially receive a high-dose, recombinant or adjuvanted flu vaccine when one is available, according to the CDC considerations. Older adults tend to have a weaker immune response to standard-dose vaccines, which is why these options exist. If you are 65 or older, ask your pharmacist or doctor which product they stock before you book.
Egg Allergy and the Flu Shot
People with an egg allergy may receive any flu vaccine that is appropriate for their age, per the CDC guidance. If you have had a severe reaction in the past, it is still reasonable to mention it to the person giving the vaccine.
Flu Vaccine for Kids: AAP Recommendations
The American Academy of Pediatrics continues to recommend annual influenza vaccination for all children 6 months and older who have no contraindications, according to a roundup from Contemporary Pediatrics. All U.S. flu vaccines this season are trivalent, meaning they target three strains. The AAP advises using any licensed, age-appropriate and health-appropriate product rather than delaying vaccination to hold out for a specific formulation.
The AAP update also expands recommendations for immunocompromised children and notes that the overall risk of febrile seizures after vaccination remains low.
Flu Treatment: Why Early Antivirals Matter
Vaccination is only part of the picture. The AAP says antiviral treatment should start as early as possible for children with suspected or confirmed influenza who are hospitalized, have severe or progressive illness, are under 5 years old, or are at increased risk for complications, regardless of vaccination status or how long symptoms have lasted. Oseltamivir remains the preferred antiviral for treatment and for post-exposure prevention. Do not wait for symptoms to get worse before calling your child’s doctor.
Where Else to Look for Guidance
Reports also note that physician groups have published their own fall vaccine guidance for 2026-27, including a September Healio story on physicians’ recommendations. Because recommendations for different vaccines can vary by organization, your own clinician is the best person to interpret what applies to you.
A Simple Flu-Season Checklist
Book your flu shot this week if you have not had one. Ask older relatives which product they should receive. Make sure kids 6 months and older are on the AAP plan. Wash hands often, stay home when sick, and call a doctor early if a high-risk family member develops flu symptoms. Sleep also matters for immune health, as we covered in our look at the Berkeley sleep study.
