The 2026-27 flu shot is free in Korea for children aged 6 months to 14 (born Jan 1, 2012 to Aug 31, 2026), pregnant women, and adults 65 and older. It runs from Sept 21, 2026 to April 30, 2027. Everyone else pays roughly ₩10,000-20,000 at a public health center or ₩20,000-40,000 at a hospital.
Our daughter is 7 in Korean age and falls into the “maybe two doses” group, so I read the official notices this week as a parent, not as a reporter. The foreigner rules rest on a 2024 report that predates this year’s changes, and I flag that where it matters.
What changed this season, and who is free?
Flu spread unusually early this year, so the Korea Disease Control and Prevention Agency (KDCA, 질병관리청, the national health authority) moved the schedule forward. All children can start from Sept 21, including one-dose children who were originally set for Sept 28. Pregnant women also started Sept 21.
Seniors begin by age band. The revised dates are Oct 6 for 75 and over, Oct 12 for 70-74, and Oct 15 for 65-69, which is three to six days earlier than the first announcement (Oct 12, 15 and 19). One trap: the Seoul city notice dated Sept 16 still shows the older dates. I use the revised ones, and I would trust the KDCA date if a district office tells you otherwise.
The other change is the child age limit. It rose from 13 to 14 this season, so a 14-year-old born in 2012 now qualifies. About 12.33 million doses are secured, roughly 4 million fewer than last season. The vaccine is trivalent (3-strain: A(H1N1), A(H3N2), B/Victoria), and all three strains changed from last year.
Why seniors first? KDCA reportedly says people 65 and older account for about 60% of severe flu hospitalizations, which is the reason given for prioritizing them.
Do foreigners qualify? The 3-month rule and the ARC
Short version: probably yes, if you are a resident. A 2024 Korea Herald report said foreigners who have lived in Korea for 3 or more consecutive months can get the free shot regardless of nationality or NHIS (National Health Insurance Service, 국민건강보험공단) enrollment. They fall into the same priority groups as Koreans and show an ARC (Alien Registration Card, 외국인등록증, the residence card) at a public health center or designated clinic. Without valid ID, a temporary management number can be issued.
Here is the catch. That report predates the age-14 expansion, and I could not find a 2026-27 notice that restates the foreigner rule. So I treat it as “the 2024 rule, very likely unchanged.” Before you drive anywhere, call the KDCA call center at 1339 and ask one question: “Does my ARC qualify for the national program shot this season?”
I think of this like the phone face-scan story I covered in September, where ARC status decided whether a Korean public system applied to us at all. In my Oct 2 child benefit post the deciding document was the child’s resident registration number; here it is the ARC plus 3 months of residence.
Two details I would not guess. A parent visiting for a short stay almost certainly does not meet the 3-month residence test, though that is my reading, not a stated rule. And I found no stated rule for how a foreign child without an ARC is handled, so ask the clinic.
Our family’s math: a 7-year-old and two doses
Children aged 6 months to under 9 who have never had a flu shot, or have had only one dose, count as two-dose children. First-timers need two shots at least 4 weeks apart. The 4-week gap comes from KDCA’s general guidance, and I did not find it restated in the 2026 notice itself, so confirm it at the desk.
Our daughter was born in 2020, so she is under 9 and her history decides the answer. I think she had one dose last winter, but I will confirm on her vaccination record before booking. If it shows no flu dose or only one, she is a two-dose child.
Here is the calendar I drew for us, assuming the first visit lands on a Saturday.
| Step | Date | Note |
|---|---|---|
| First dose | Sat, Oct 10, 2026 | Any designated clinic, free for ages 6 months-14 |
| Earliest second dose | Sat, Nov 7, 2026 | 28 days later is the minimum, not a target |
| Comfortable window | Nov 7-21 | Leaves room for a sick day or a missed Saturday |
| Program ends | Apr 30, 2027 | Doses cannot wait until spring |
Counting it out showed me the real constraint: the second dose can never come sooner than 4 weeks after the first, so every week I wait on dose one pushes dose two a week closer to the peak. With flu already early this year, I am booking the first dose this weekend, not “sometime in October.”
Who pays what: the household table
I built this table for households like ours, and added the rows we do not have, since a family rarely lands in one category. It shows the free-or-paid status for each member, the start date, and what to bring.
| Household member | Free or paid | Start date | Bring | Cost |
|---|---|---|---|---|
| Child under 9, no flu history or one prior dose | Free, 2 doses | Sept 21 | Insurance card or proof of eligibility | ₩0 |
| Child 9-14 (born 2012 or later) | Free, 1 dose | Sept 21 | Insurance card or proof of eligibility | ₩0 |
| Pregnant spouse | Free | Sept 21 | Maternal handbook or pregnancy confirmation | ₩0 |
| Healthy adult, 19-64 | Paid | Any time | ARC, payment | ₩10,000-20,000 (health center), ₩20,000-40,000 (hospital) |
| Parent aged 65+ | Free | Oct 6 (75+), Oct 12 (70-74), Oct 15 (65-69) | ID | ₩0 |
For our three-person household the math is simple: my daughter is free, my wife is free only if she were pregnant (she is not, so she pays too), and I am paid as well. Two adults at a hospital is ₩40,000-80,000. A public health center would cut that to ₩20,000-40,000 for two adults.
Paid shots are 비급여 (bigeubyeo, “non-reimbursable”), meaning NHIS does not cover them and each clinic sets its own price. Whether a private insurance plan reimburses a flu shot depends on the policy, so I would not assume it does. The private route also gives you the 4-valent vaccine, which the national program does not use.
At the clinic: find one, bring the right things, say the right words
Roughly 23,000 designated clinics and public health centers take part. You can use any of them regardless of where you live. Search on the KDCA vaccination site, nip.kdca.go.kr, or simply call a nearby pediatric or internal-medicine clinic and ask if they carry the national program vaccine. I would call first, because stock varies from clinic to clinic.
Bring the ARC, your insurance card, and for a child any vaccination record you have. For a pregnant spouse, bring the maternal handbook (산모수첩, the pregnancy record booklet) or a pregnancy confirmation. For a parent aged 65+, bring a photo ID.
At the desk, say: “국가예방접종 독감 주사 맞으러 왔어요” (guk-ga-ye-bang-jeop-jong dok-gam ju-sa ma-jeu-reo wa-sseo-yo, “I came for the national program flu shot”). Add “아이는 두 번 맞아야 해요” (a-i-neun du beon ma-ja-ya hae-yo, “my child needs two shots”) when it is a first-time child, so the nurse books the second dose before you leave.
Flu plus COVID in one visit, and when I would just pay
The national COVID-19 vaccination for 2026-27 starts Oct 12 for ages 70+ and immunocompromised people 12 and older, and Oct 15 for ages 65-69. It runs through June 30, 2027. KDCA says flu and COVID shots can be given at the same visit, which matters for any 65+ parent staying with you.
When does paying make sense? If you are 19-64 and healthy, you are not in a free group, so the real choice is only where. I would take the ₩10,000-20,000 public health center slot first, and pay the hospital ₩20,000-40,000 only if the health center has no stock or no weekend hours.
For my own plan: this Saturday my daughter gets dose one, I book dose two for Nov 7 before we leave the desk, and my wife and I pay for ours at a public health center the following week. I will call 1339 first, because the one thing I cannot confirm from here is the foreigner rule as it applies to a family with mixed paperwork.
