Check Whether People in Their 40s and 50s Qualify for This Year's Free Flu Shot

Who is eligible for this year's national influenza vaccination?

The KDCA named children aged 6 months to 14, pregnant women, and adults 65 and over as eligible for the 2026-2027 season national influenza vaccination. The children's group has widened from 13 to 14 starting this season, and covers children born between January 1, 2012 and August 31, 2026.

Being in your 40s or 50s does not by itself put you in this national support group. Pregnant women, however, are a separate eligible group. For support outside the national program and the cost of a paid shot, ask your local public health center or a medical institution.

When does vaccination start for each age group?

The KDCA said that because this year's flu season started earlier than usual, it is moving up the schedule for children and older adults. These are the start dates as confirmed from the September 16, 2026 press release.

For older adults, the birth date ranges stated in the August announcement have been organized by year. Don't calculate age by whether your birthday has passed on the day of vaccination. Match by birth year instead.

For children, the start date above applies regardless of how many doses they need. The pregnant women's start date is the same as in the August 25 announcement. The end date of national support was announced as April 30, 2027. Even after the start date has passed, availability can differ by institution, so check first.

Where do you get vaccinated?

You can be vaccinated at a designated medical institution or a public health center, and you aren't tied to where you live. In its September 2026 press release, the KDCA put the number of designated institutions at about 23,000. It advises checking a location under Vaccination Management, then Find Designated Medical Institutions, on the Vaccination Helper site, or with your local public health center.

Your address doesn't have to match, so you can use a clinic near your workplace. It's safer to call beforehand and ask whether that institution has started this year's influenza shots.

What should people in their 40s and 50s check before getting vaccinated?

Even if you aren't in the national support group, the medical institution will tell you whether you can get the shot there. There are three things to check beforehand.

• Whether the institution has started giving shots this year
• The cost of the shot if you aren't an eligible recipient
• Whether you can get a consultation on vaccination if you have a chronic condition or a weakened immune system

In the press release, the October 6 early-vaccination exception is attached only to the older-adult schedule. It does not mean national support expands to everyone in their 40s and 50s just because their immunity is weak. Talk to the doctor treating you about the right timing for you.

What should you do first to arrange your parents' vaccination?

If your parents were born through 1961, find the start date in the birth-year row of the table above. Next, find a designated medical institution near home or work on the Vaccination Helper site. Finally, call the clinic before you go to ask whether it has started vaccinating, its office hours, and whether you need an appointment.

Confirming the date does not guarantee you'll get the shot. The KDCA adjusted the schedule with supply and institutions' readiness in mind, so check that the place you plan to visit actually has the vaccine available.

When should you contact a medical institution?

Ask your doctor about questions on your personal situation, such as current conditions, the medications you take, and vaccination intervals. If you have a fever or respiratory symptoms, see a doctor.
