Baby Vaccination Schedule in Korea: A Guide for Foreign Parents

Korea has a nationally managed childhood vaccination system, but its vaccine names, clinic types, online records, and registration procedures may be unfamiliar to foreign parents. This guide explains when babies are usually vaccinated, where to receive vaccines, and how to check or register a child’s immunization record in Korea.

Foreign parents raising a baby in Korea usually deal with two connected parts of the vaccination system:

  1. A pediatric clinic or public health center administers the vaccine.
  2. The clinic registers the dose in the national immunization database managed by the Korea Disease Control and Prevention Agency, or KDCA.

Under Korea’s National Immunization Program, commonly shortened to NIP, eligible children can receive nationally supported vaccines without paying the vaccine or administration cost at public health centers and designated private medical institutions.

As of 2026, Korea’s childhood NIP supports 19 vaccine types. However, eligibility ages, vaccine products, and seasonal program periods differ by vaccine. A clinic that does not participate in the NIP may charge the full cost even for a vaccine that is normally supported.

For most foreign parents, the practical process is simple:

  1. Check which vaccine is due.
  2. Find a participating pediatric clinic or public health center.
  3. Confirm that the vaccine is available.
  4. Bring your child’s identification and vaccination records.
  5. Receive the vaccine after a doctor’s pre-vaccination examination.
  6. Check that the dose appears in the national immunization record.

The schedule in this article is a general overview. Your child’s actual schedule may differ because of previous doses, vaccine products, premature birth, medical conditions, maternal hepatitis B status, or vaccinations received outside Korea.

Quick Answer: How Baby Vaccinations Work in Korea

Babies in Korea normally begin receiving routine vaccines at birth. The busiest vaccination periods are generally:

  • Birth
  • 1 month
  • 2 months
  • 4 months
  • 6 months
  • 12–18 months

Common childhood vaccines protect against diseases such as:

  • Hepatitis B
  • Tuberculosis
  • Diphtheria
  • Tetanus
  • Pertussis
  • Polio
  • Haemophilus influenzae type b
  • Pneumococcal disease
  • Rotavirus
  • Measles, mumps, and rubella
  • Varicella
  • Hepatitis A
  • Japanese encephalitis
  • Influenza

Vaccinations are commonly given at a neighborhood pediatric clinic, written as 소아청소년과 in Korean, or at a local public health center, called 보건소.

Not every private pediatric clinic is automatically part of the government program. Parents should confirm that the clinic is an official NIP-designated medical institution, known in Korean as a 위탁의료기관. The KDCA’s Immunization Assistance service allows parents to search by region, medical institution, and available vaccine.

Important Vaccination Terms for Foreign Parents

Vaccination schedule

A vaccination schedule is the recommended timing and spacing of vaccine doses according to a child’s age.

It does not mean that every baby must receive a vaccine on one exact calendar date. The doctor considers:

  • The child’s date of birth
  • Previous vaccination dates
  • The child’s current age
  • Minimum intervals between doses
  • The vaccine product used
  • Health conditions or previous reactions

When a vaccination has been delayed, the remaining schedule may need to be recalculated.

Baby vaccine

A baby vaccine is a vaccine given during infancy or early childhood to help the immune system develop protection against a particular infectious disease.

Several vaccines may be administered during the same appointment. A clinic may also use a combination vaccine, which protects against several diseases in a single injection.

Pediatric clinic

A pediatric clinic specializes in medical care for babies, children, and adolescents.

In Korea, look for the Korean term:

소아청소년과
Pediatrics

Most pediatric clinics are privately operated. Many, but not all, participate in the National Immunization Program.

Public health center

A public health center, or 보건소, is a local government health facility.

Depending on the district, it may provide childhood vaccinations and help with:

  • Registering overseas vaccination records
  • Correcting missing vaccination information
  • Issuing vaccination certificates
  • Creating a temporary vaccination management number
  • Confirming eligibility for government-supported vaccines

Services, vaccine stock, and operating hours differ by public health center. Calling before visiting is strongly recommended.

Immunization record

An immunization record is the official history of vaccines received by a child.

It normally shows:

  • Vaccine name
  • Dose number
  • Vaccination date
  • Medical institution
  • Registered vaccine information

Vaccinations administered by participating Korean institutions are normally entered electronically into the KDCA system.

Korea Baby Vaccination Schedule

The following table summarizes the main routine vaccination periods for babies and young children in Korea.

It is an overview rather than a personalized medical schedule. Combination vaccines, rotavirus products, Japanese encephalitis vaccine types, and delayed schedules can result in different dose numbers or timing.

Child’s AgeTypical Vaccines or Milestones
At birthHepatitis B first dose
Within 4 weeks after birthIntradermal BCG vaccine for tuberculosis
1 monthHepatitis B second dose under the standard standalone schedule
2 monthsFirst doses of DTaP, polio, Hib, pneumococcal, and rotavirus vaccines; hepatitis B may be included in a six-component combination vaccine
4 monthsSecond doses of DTaP, polio, Hib, pneumococcal, and rotavirus vaccines
6 monthsThird doses of several infant vaccines; third rotavirus dose when using a three-dose product; influenza vaccination may begin
6–18 monthsThird polio dose may be administered during this period
12–15 monthsFirst MMR dose, varicella vaccine, Hib booster, and pneumococcal booster
12–23 monthsHepatitis A series and Japanese encephalitis vaccination generally begin
15–18 monthsFourth DTaP dose
18–35 monthsFollow-up hepatitis A and Japanese encephalitis doses, depending on the vaccine and previous dates
4–6 yearsDTaP booster, polio booster, and second MMR dose
Later childhoodTdap or Td, Japanese encephalitis boosters, seasonal influenza, and HPV for eligible age groups

The KDCA advises parents to follow the standard schedule whenever possible. When a dose is late, the required number and timing of later doses may change according to the child’s age.

Why Two Babies May Receive Different Numbers of Injections

Two babies of the same age may receive a different number of injections during the same vaccination period.

This does not necessarily mean that one child is missing a vaccine.

Korean clinics may use combination products such as:

  • DTaP-IPV
  • DTaP-IPV/Hib
  • DTaP-IPV-Hib-HepB

The six-component vaccine combines protection against:

  • Diphtheria
  • Tetanus
  • Pertussis
  • Polio
  • Hib
  • Hepatitis B

Korea’s 2026 National Immunization Program includes the six-component DTaP-IPV-Hib-HepB vaccine among its supported vaccine types.

The product selected may depend on:

  • Vaccines previously received
  • The clinic’s available stock
  • The baby’s age
  • The mother’s hepatitis B test results
  • The doctor’s assessment

A baby born to a mother with hepatitis B requires a specific perinatal prevention plan. Parents should not assume that the standard combination-vaccine schedule applies without a doctor reviewing the mother’s test results and the baby’s birth records.

Vaccine-Specific Details Foreign Parents Should Know

BCG: Intradermal and percutaneous vaccines are different

BCG is the vaccine used to protect babies from severe forms of tuberculosis.

The BCG vaccine supported under Korea’s National Immunization Program is the intradermal BCG vaccine, known as 피내용 BCG. It is normally recommended within four weeks after birth.

A different method, called percutaneous BCG or 경피용 BCG, may be available at some private clinics. It uses a multipuncture device rather than a single intradermal injection.

Percutaneous BCG is not included in the standard NIP support program and is generally paid for privately.

Before making an appointment, ask:

피내용 BCG인가요, 경피용 BCG인가요?
Is this intradermal BCG or percutaneous BCG?

Do not choose solely by comparing the number or appearance of marks left on the skin. Ask the pediatrician to explain the method, national recommendation, availability, and cost.

Rotavirus vaccine has strict age limits

Rotavirus vaccine is given orally rather than by injection.

Korea uses two common schedules:

Product TypeUsual Schedule
Two-dose product2 and 4 months
Three-dose product2, 4, and 6 months

The first dose must be given no later than 14 weeks and 6 days of age. The full series must be completed by 8 months and 0 days of age.

The KDCA states that the first rotavirus dose should not be started from 15 weeks and 0 days onward, and no rotavirus dose should be given after the maximum age limit. The same manufacturer’s product should generally be used throughout the series.

Because this vaccine has strict age limits, contact a pediatric clinic promptly when the first dose has been delayed.

Influenza vaccination can begin at 6 months

Babies can begin receiving influenza vaccination from 6 months of age.

A child receiving influenza vaccination for the first time may need two doses during the first vaccination season, depending on the child’s age and previous influenza vaccination history.

Korea’s influenza support program operates seasonally. The eligible ages and exact start and end dates are announced separately for each influenza season. Parents should check the current announcement rather than relying on dates from the previous year.

Japanese encephalitis has more than one schedule

Japanese encephalitis vaccination can be confusing because Korea uses both inactivated and live vaccine schedules.

Inactivated Japanese encephalitis vaccine

The usual childhood schedule is:

  1. First dose between 12 and 23 months
  2. Second dose approximately one month later
  3. Third dose approximately 11 months after the second dose
  4. Additional doses at 6 and 12 years of age

Live Japanese encephalitis vaccine

The usual schedule is:

  1. First dose between 12 and 23 months
  2. Second dose approximately 12 months later

The KDCA does not routinely recommend switching between the inactivated and live Japanese encephalitis vaccine schedules.

Parents should keep a record of exactly which type and product the child received. The next dose cannot be determined correctly from the words “Japanese encephalitis vaccine” alone.

Where Can a Baby Receive Vaccinations in Korea?

Option 1: A designated pediatric clinic

For many families, a neighborhood pediatric clinic is the easiest option.

Before visiting, confirm that:

  • The clinic participates in the National Immunization Program.
  • It administers the vaccine your baby needs.
  • The vaccine is currently available.
  • A reservation is required or not required.
  • The clinic can review overseas vaccination records, when necessary.

The KDCA’s Immunization Assistance service, called 예방접종도우미, includes a designated medical institution search function.

To find it, search for:

KDCA Immunization Assistance
예방접종도우미

The service is available through the official KDCA website and provides vaccination schedules, child vaccination history, certificate services, and a search tool for participating medical institutions. Vaccine stock can still change, so call the clinic before visiting.

Option 2: A public health center

A local public health center may also provide childhood vaccinations.

It can be especially useful when:

  • The baby does not yet have a Korean registration number.
  • Vaccination records from another country must be reviewed.
  • A dose is missing from the electronic record.
  • The family needs an official vaccination certificate.
  • The child’s Korean and overseas records do not match.
  • The parents are unsure about NIP eligibility.

Not every public health center provides every vaccine on every working day. Some require reservations or operate vaccination services only during certain hours.

How to Make a Vaccination Appointment

Korea does not use one universal appointment system for every pediatric clinic.

Depending on the clinic, parents may use:

  • A telephone reservation
  • A Korean medical appointment app
  • The clinic’s website
  • A walk-in visit

A practical appointment process is:

  1. Check your child’s vaccination record and expected schedule.
  2. Search for a designated medical institution in your area.
  3. Select a nearby pediatric clinic or public health center.
  4. Call before visiting.
  5. State your baby’s date of birth or current age.
  6. Tell the clinic which vaccine appears to be due.
  7. Ask whether the product is available.
  8. Confirm whether an appointment is necessary.

Useful Korean sentences include:

아기 예방접종 예약하고 싶어요.
I would like to make a vaccination appointment for my baby.

생후 4개월 예방접종이 가능한가요?
Can my four-month-old baby receive the scheduled vaccinations here?

이 병원은 국가예방접종 위탁의료기관인가요?
Is this clinic a designated National Immunization Program provider?

오늘 로타바이러스 백신이 있나요?
Is the rotavirus vaccine available today?

해외 예방접종 기록도 확인해 주실 수 있나요?
Can you also review an overseas vaccination record?

What to Bring to the Clinic

The KDCA advises guardians to bring identification and the child’s vaccination booklet or other vaccination record when visiting a designated medical institution.

Foreign parents should prepare:

  • Parent or guardian identification
  • Passport or residence card
  • Child’s Korean registration information, when available
  • Health insurance information, when applicable
  • Child’s vaccination booklet
  • Official overseas immunization certificate
  • Records of allergies or previous vaccine reactions
  • Information about current medication
  • Information about recent fever or illness

At the clinic, the parent normally completes a pre-vaccination screening questionnaire, called a 예방접종 예진표.

This form may ask about:

  • The child’s current health
  • Recent fever or illness
  • Previous vaccinations
  • Previous adverse reactions
  • Allergies
  • Current medication
  • Immune system conditions
  • Recent blood products or immunoglobulin treatment

The KDCA form accepts a resident registration number or foreign resident registration number and includes information needed for the vaccination examination and record system.

How to Check Your Baby’s Immunization Record

There are three main ways to confirm a baby’s vaccination history in Korea.

Method 1: Use KDCA Immunization Assistance

The primary online service is the KDCA’s Immunization Assistance website, called 예방접종도우미.

The general process is:

  1. Create an account or log in.
  2. Register the parent’s identity information.
  3. Register the child’s information.
  4. Open the child vaccination management menu.
  5. Select the vaccination history page.
  6. Review the vaccine name, dose number, date, and medical institution.
  7. Check the expected date of the next vaccine.

The service includes:

  • Child information registration
  • Vaccination history
  • Vaccination schedule
  • Designated clinic search
  • Vaccination certificate services
  • Pre-vaccination questionnaire services

Foreign users may experience identity-verification problems if the spelling, spacing, or order of a name differs between the website account and the registered identification document.

For example, these may be treated as different entries:

  • PARK MIN SU
  • MIN SU PARK
  • PARK MINSU

Use the exact registered name format whenever possible. If the child cannot be connected to the account because the information does not match, contact the KDCA system support service or a public health center rather than creating duplicate child records.

Method 2: Request a vaccination certificate

Parents can request an official vaccination certificate, called a 예방접종증명서.

The certificate may be available in Korean or English through:

  • KDCA Immunization Assistance
  • Government24
  • A public health center
  • The medical institution that registered the vaccination

An English vaccination certificate may be needed for:

  • Moving to another country
  • International school admission
  • Daycare or school registration
  • Immigration documents
  • Overseas medical care
  • Comparing Korean and foreign schedules

Government24 also provides an online vaccination certificate service after the child has been properly registered.

Method 3: Ask the clinic or public health center

Parents can ask the institution that administered the vaccine to confirm the record.

The online system displays vaccinations that have been electronically registered. If a dose was administered but does not appear, contact the clinic that gave the vaccine and request that it check the electronic registration.

Keep both the paper record and the electronic record, especially immediately after vaccination. Electronic registration may not always appear instantly.

What If the Child Was Vaccinated Outside Korea?

An overseas vaccination booklet does not automatically appear in Korea’s national system.

Obtain an official vaccination certificate containing as much of the following information as possible:

  • Child’s full name
  • Date of birth
  • Vaccine or antigen name
  • Date of each dose
  • Dose number
  • Vaccine product or manufacturer, when available
  • Lot number, when available
  • Medical institution name
  • Doctor’s signature or institutional stamp

The KDCA advises parents to obtain an English vaccination certificate and take it to a Korean public health center to request registration of the overseas vaccination history.

A clear English certificate is usually more useful than:

  • A parent’s handwritten list
  • A photograph without identifying information
  • A document showing only trade names
  • A record without dates
  • A record that cannot be connected to the child

The public health center reviews whether the documentation is sufficient for electronic registration. It may ask for additional information when the vaccine name, dose, date, or administering institution cannot be verified.

Registering the overseas record is important because it can:

  • Prevent unnecessary duplicate vaccinations
  • Help the doctor create a correct catch-up schedule
  • Produce a more complete Korean certificate
  • Make daycare or school documentation easier

Do not translate or interpret unclear vaccine names yourself and then enter them as confirmed doses. Take the original documentation to a pediatrician or public health center.

What If the Baby Does Not Have a Korean Registration Number?

A foreign baby may not yet have a Korean foreign resident registration number because the birth registration or immigration process is incomplete.

The KDCA states that a public health center may issue a temporary vaccination management number when a person cannot obtain a resident or foreign resident registration number for unavoidable reasons.

The guardian generally needs to:

  1. Contact the public health center.
  2. Confirm the required documents.
  3. Visit the center in person.
  4. Bring identification such as a passport.
  5. Request a temporary management number.
  6. Later ask for the records to be connected or corrected after an official registration number is issued.

Document requirements can vary according to the child’s situation. The public health center may request:

  • Parent’s passport
  • Child’s passport
  • Birth certificate
  • Proof of relationship
  • Immigration documents
  • Korean or English translations

Call the center before visiting rather than assuming that one document will be sufficient.

Are Baby Vaccinations Free for Foreign Children?

Under Korea’s National Immunization Program, the vaccine and administration costs of supported childhood vaccinations are fully covered for eligible children at public health centers and designated medical institutions.

In 2026, the main childhood program covers children age 12 or younger, although individual vaccines have their own age limits. The supported list includes 19 vaccine types.

Foreign children can be managed within the Korean vaccination system, but their identity and vaccination registration must be processed correctly.

Parents may still have to pay when:

  • The clinic is not an NIP-designated institution.
  • The selected vaccine product is not covered.
  • The child is outside the supported age range.
  • The vaccine is optional rather than nationally supported.
  • The dose does not meet the program’s timing or eligibility rules.
  • Additional examination or treatment is provided separately.

Examples of products that may require private payment include:

  • Percutaneous BCG
  • Certain non-supported Japanese encephalitis products
  • HPV products outside the supported program conditions

Always confirm the cost before vaccination when selecting a specific product or visiting a non-designated clinic.

What Happens If a Vaccination Is Late?

A delayed vaccination series usually does not need to be restarted from the beginning.

The KDCA states that even when the interval becomes longer than normally recommended, it is generally unnecessary to restart the entire series or add extra doses solely because of the delay. The remaining doses should be completed according to a doctor-approved catch-up schedule.

However, the next schedule may change according to:

  • The child’s current age
  • The doses already received
  • Minimum dose intervals
  • The vaccine product
  • Vaccine-specific age limits
  • The child’s medical history

Vaccines including DTaP, polio, Hib, pneumococcal, and Japanese encephalitis may require different timing or dose numbers when vaccination begins late.

Rotavirus is especially time-sensitive because the first dose and final dose have strict maximum ages.

Do not independently repeat a vaccine or choose a catch-up date from a general online table. Take the complete vaccination record to a pediatrician or public health center and request an individual catch-up plan.

Before the Vaccination

Tell the doctor if your child:

  • Has a fever or appears unwell
  • Recently received another vaccine
  • Had a serious reaction to a previous dose
  • Has a known vaccine or medication allergy
  • Has an immune system disorder
  • Is taking immunosuppressive medication
  • Recently received blood products or immunoglobulin
  • Was born prematurely
  • Has a chronic medical condition
  • Was vaccinated outside Korea

A mild illness does not automatically mean that vaccination must be postponed, but the decision should be made by the examining doctor.

After the Vaccination

Follow the clinic’s instructions after vaccination.

Parents are commonly advised to:

  • Remain at the clinic for the recommended observation period.
  • Watch for immediate allergic reactions.
  • Keep the injection site clean.
  • Monitor the child’s temperature and behavior.
  • Confirm the next vaccination date.
  • Seek medical advice for concerning or worsening symptoms.

Mild pain, redness, swelling, irritability, or fever may occur after some vaccines. Symptoms vary according to the vaccine and the child.

Seek urgent medical care when the child develops symptoms such as:

  • Difficulty breathing
  • Facial or throat swelling
  • Loss of consciousness
  • A seizure
  • Severe weakness
  • Persistent high fever
  • Unusual unresponsiveness
  • Rapidly worsening symptoms

For a medical emergency in Korea, call 119.

A Simple Decision Guide for Foreign Parents

Your baby has a Korean registration number and no overseas records

Use KDCA Immunization Assistance to check the schedule, find a designated clinic, and confirm the vaccination afterward.

Your baby was vaccinated in another country

Obtain an official English vaccination certificate and take it to a public health center for review and possible registration.

Your baby has no Korean registration number yet

Contact the local public health center and ask whether a temporary vaccination management number can be issued.

A vaccine is missing from the online record

Contact the clinic that administered it and request verification or electronic registration.

A scheduled vaccine is late

Do not restart or repeat doses yourself. Ask a pediatrician to calculate a catch-up schedule.

You want a specific vaccine brand or product

Call the clinic in advance. Participating clinics may offer different products, and stock information can change.

Frequently Asked Questions

Can foreign parents take their baby to a Korean pediatric clinic?

Yes. Foreign families can use pediatric clinics in Korea.

For government-supported vaccination, confirm that the clinic is an NIP-designated medical institution and that the child’s vaccination registration information is properly connected.

Do I need Korean National Health Insurance for baby vaccinations?

The National Immunization Program is not identical to ordinary health insurance coverage.

Eligible NIP vaccinations are supported through the national vaccination program, but the child still needs appropriate identity and vaccination registration. Families with incomplete immigration or registration documents should contact a public health center before the appointment.

Do pediatric clinics require appointments?

It depends on the clinic.

Some accept walk-in patients, while others require telephone or app reservations. Calling first is recommended because a clinic may not have every vaccine or product available that day.

Can several vaccines be given on the same day?

Several routine childhood vaccines can often be administered during one visit. Combination vaccines can also reduce the number of injections.

The doctor should decide which vaccines can be given after reviewing the child’s age, health, and previous vaccination record.

Can I get an English immunization certificate in Korea?

Yes.

English vaccination certificates may be available through KDCA Immunization Assistance, Government24, or an issuing public health or medical institution after the child’s records have been properly registered.

Why is a vaccination missing from the online record?

The system displays doses electronically registered by medical institutions.

Contact the clinic that administered the missing dose and ask it to verify the vaccination and complete the electronic registration.

Can vaccines received in another country be added to the Korean system?

Yes, they may be registered after document review.

Obtain an official English vaccination certificate and take it to a Korean public health center. Registration may not be possible when the vaccine name, date, child’s identity, or administering institution cannot be verified.

Does a late vaccination series need to start again?

Usually not.

The doctor normally uses the valid doses already received and creates a catch-up schedule. However, some vaccines have maximum ages or age-dependent schedules, so medical review is necessary.

What should I do if my baby has a cold on vaccination day?

Tell the pediatrician about the baby’s temperature, symptoms, and recent health.

Do not cancel or proceed solely because of a general rule found online. The examining doctor should decide whether the vaccine can be given or should be postponed.

Why did my baby receive fewer injections than another baby?

The clinic may have used a combination vaccine that protects against several diseases in one injection.

Compare the vaccine names and antigens in the records rather than comparing only the number of injections.

Is percutaneous BCG free under the national program?

Generally, no.

The nationally supported BCG option is intradermal BCG. Percutaneous BCG is normally a private, self-paid option. Confirm the method and cost before the appointment.

Can rotavirus vaccination be started late?

The first dose must be administered by 14 weeks and 6 days of age, and the entire series must be completed by 8 months and 0 days.

Contact a pediatrician immediately when the first dose has been delayed. Do not assume that the schedule can simply be moved to a later month.

Can a baby without a foreign resident registration number receive vaccines?

A public health center may issue a temporary vaccination management number when the baby cannot yet receive an official registration number for unavoidable reasons.

The guardian must normally visit the public health center with identification after confirming the required documents by telephone.
