Planning a trip to Southeast Asia, India, or Africa? Passport — check. Flights — booked. But what about your hepatitis A vaccine before travel?
Hepatitis A spreads through contaminated food and water, and adults often experience far more severe symptoms than children. A bad case can put you in bed for weeks — wrecking the trip you spent months planning.
Get your first hepatitis A vaccine at least 2 weeks before departure — ideally 4–6 weeks out. One dose may provide about 95% protection. If you’re over 40, consider an antibody test first. In Korea, each dose costs roughly ₩50,000–₩100,000 (about $37–$73 / approx. ¥5,500–¥11,000) at a private clinic.
Do I really need a hepatitis A vaccine before traveling?
Yes — especially if you’re heading to a high-risk region.
Hepatitis A is an acute viral liver infection caused by the hepatitis A virus (HAV), which spreads through contaminated food, water, and the fecal-oral route.
The CDC and WHO classify these as high-risk areas: Southeast Asia (Thailand, Vietnam, Indonesia, Philippines), India, the Middle East, Africa, Central and South America, Eastern Europe, and Central Asia. Western Europe, North America, Japan, and Australia are low-risk.
Adults who contract hepatitis A can experience jaundice, extreme fatigue, nausea, and abdominal pain lasting several weeks. Rare but serious complications include acute liver failure. Vaccination is the most effective way to protect yourself.
High-risk destinations: Southeast Asia, India, Middle East, Africa, Latin America, Eastern Europe, Central Asia
Low-risk destinations: USA, Canada, Western Europe, Japan, Australia, New Zealand

How many weeks before my trip should I get the hepatitis A vaccine?
Get vaccinated at least 2 weeks before travel — 4 to 6 weeks ahead is ideal.
It takes about 2–4 weeks for your immune system to build full protection after the first dose. Even if your trip is just days away, the CDC still recommends getting vaccinated rather than skipping it entirely. Same-day vaccination before a flight still provides meaningful benefit.
✅ Dose 1: At least 2 weeks before departure (ideally 4–6 weeks)
✅ Dose 2: 6–12 months after the first dose
✅ Single dose: ~95% protection expected
✅ Full 2-dose series: Immunity may last 20+ years

In Korea, the most commonly used vaccines are Havrix (GSK) and Avaxim (Sanofi). Both are approved for ages 12 months and older. A combination hepatitis A+B vaccine (Twinrix, GSK) is available for adults 18 and over.
Do I need an antibody test first? Who should get vaccinated?
Under 40: skip the antibody test and get vaccinated right away. Over 40: test first, then vaccinate if the result is negative.
People born before the mid-1980s in Korea grew up when sanitation was less reliable. Many were naturally exposed to HAV as children and may already carry lifelong immunity. An anti-HAV IgG antibody test can confirm this.
✅ Under 40: No antibody test needed — get 2 doses
✅ Over 40 (born before ~1986): Get antibody test first → vaccinate if negative
✅ Previous HAV infection: Likely immune — confirm with test
✅ Children (12 months+): Free under Korea’s National Immunization Program (NIP)

In Korea, the antibody test costs roughly ₩15,000–₩50,000 ($11–$37) depending on the clinic. Bogenso (보건소 — local public health centers operated by regional governments) often charge less.
Vaccination is typically listed as non-covered under Korea’s National Health Insurance (건강보험, geongang boheom). If you carry silson insurance (실손보험 — Korean private indemnity health insurance), check your policy for possible reimbursement.

To find a participating clinic near you, use the KDCA’s National Immunization Program website at nip.kdca.go.kr. You can filter by location and book appointments online at many health centers.
If cost is a concern, call your nearest bogenso before booking a private clinic. Prices at health centers are often significantly lower, and some run seasonal discount or free vaccination programs.
Frequently Asked Questions
1. Can I travel with just one dose of the hepatitis A vaccine?
Yes. A single dose may provide around 95% protection, which is considered sufficient for most short trips. You can complete the second dose after returning home. A full series is recommended for long-term or repeated travel to high-risk destinations.
2. I had hepatitis A before. Do I still need the vaccine?
Natural infection likely provides lifelong immunity. If you’re certain about a past infection, an antibody test can confirm it. If the test is positive, vaccination is unnecessary. Consult a doctor to be sure.
3. Is the hepatitis A vaccine safe during pregnancy?
Hepatitis A vaccines are inactivated (not live), so theoretical risk is low. However, pregnant travelers should consult an OB-GYN or infectious disease specialist before getting vaccinated.
4. My child is under 1 year old. What are the options for travel to a high-risk area?
The vaccine is approved for children aged 12 months and older. For infants under 12 months, immune globulin (IG) may be considered as a short-term option — discuss this with a pediatrician before departure.
