Your Fall Flu Shot Guide: What Doctors Want Gen Z to Know

Somewhere between the first week of classes and the first pumpkin-spice sighting, flu season quietly begins. This year the message around it is louder than usual, and it is aimed squarely at people in their twenties. Doctors across the country are urging everyone, including young and healthy adults, to get a fall flu shot this year, according to coverage from local news outlets this week.

That might sound strange if you rarely get sick. Most years, the flu shot conversation revolves around grandparents and toddlers. This time, health officials are deliberately widening the circle. The virus spreads fastest when people spend more time indoors together, which is exactly how most of us spend the season: in classrooms, offices, dorms, and packed trains from fall through spring. Getting vaccinated before respiratory virus season is one of the best ways we can stay healthy and protect the people we love, Margot Savoy, the chief medical officer of the American Academy of Family Physicians, said at the 2026 NFID Annual Respiratory Season Kick-Off in Washington, D.C.

Why this fall's vaccine advice looks different

The guidance itself looks different this season. Four major medical groups, the American Academy of Family Physicians, the American Academy of Pediatrics, the American College of Obstetricians and Gynecologists, and the Infectious Diseases Society of America, released coordinated recommendations for the flu, COVID, and RSV vaccines in early September. They moved first because the CDC's vaccine advisory panel had not issued new COVID or RSV recommendations for this season, and the CDC only carried over last year's flu guidance, according to reporting by MedicalDaily. The CDC also merged its flu and COVID divisions into a single respiratory virus unit as the season approached.

The medical groups did not make the call lightly. The American Medical Association and the Vaccine Integrity Project at the University of Minnesota reviewed hundreds of studies of the flu, COVID, and RSV vaccines, and the findings were published in the Journal of the American Medical Association. "This year's review confirms that the newest evidence remains consistent with research showing these immunizations reduce the risk of hospitalization and death among the people most likely to experience serious disease," Michael Osterholm, executive director of the Vaccine Integrity Project, said in a news release, as reported by PhillyVoice.

For young adults, the bottom line from the new guidance is simple. The doctors' groups recommend an annual flu shot for everyone six months and older, and a COVID shot for adults nineteen and up. The flu recommendation is not new, but the emphasis on it is. Doctors are now saying the shot matters for the healthy twenty-five-year-old who visits their parents at Thanksgiving just as much as it matters for those parents.

What the numbers actually say

Last season's numbers explain the urgency. The flu caused tens of millions of cases in the United States, sent hundreds of thousands of people to the hospital, and killed tens of thousands, according to CDC estimates reported by PhillyVoice. COVID added millions more cases and hundreds of thousands of hospitalizations. RSV caused millions of outpatient visits and up to twenty-five thousand deaths. The American Academy of Pediatrics added a sobering detail for families: the last flu season killed about one hundred ninety children, and about eighty-five percent of child flu deaths occur in kids who were not vaccinated.

COVID has not gone away either. Wastewater surveillance from the WastewaterSCAN program shows that national COVID levels in September ran more than half higher than in August, and levels in the West and South have surpassed the previous winter's peak, according to reporting by Herald-Mail Media. CDC estimates suggest COVID infections are growing or probably growing in more than two dozen states right now.

Dr. Don Brannen, an epidemiologist with Greene County Public Health, put it bluntly in an interview with Dayton 24/7 Now: "The virus doesn't care who it affects; it's that it is doing its job of attaching to our mucosal cells and the lining of our upper airway, and it'll spread down and sometimes get deep in the lungs, and that can cause pneumonia."

Your game plan for October

October is the ideal time to get your fall flu shot, according to Scott Roberts, a Yale Medicine infectious diseases specialist, in an interview with Yale News. The flu shot needs a couple of weeks to build protection, so going in October means you are covered before the season peaks in winter. Vaccination options this year include the traditional shot in the arm and a nasal spray version, and a new mRNA-based flu vaccine is debuting for people fifty and older, which is worth mentioning to your parents.

Roberts also made the case for why the shot matters even if you are not high risk. The flu is one of the "big three" viruses, along with COVID and RSV, that cause most hospitalizations for respiratory viruses every year, he said in the Yale News interview, and he added that vaccination remains the single best defense: "The best tool we have against flu is the vaccine."

If you live with or regularly visit older relatives, there is an extra reason to act early. Roberts told Yale News he encourages lower-risk people to get vaccinated when they plan to spend time around higher-risk family members, and he noted that antiviral medications like Tamiflu can protect the rest of a household if one person tests positive for flu.

The practical part is easy. Flu shots are available at pharmacies and clinics with no appointment in most places, and most insurance plans cover them. A recent survey released at the NFID kickoff found that most American adults support vaccines but many are confused about which respiratory vaccines they actually need, so consider this your reminder: if you are six months or older, the flu shot is for you. Check with a health care provider or your local pharmacy if you have questions about COVID or RSV shots too. Your future self, and your grandma, will thank you.
