Hawaii: Your Gateway to International Travel Health
A complete guide for Hawaii-based travelers preparing for international trips — vaccines, regulations, clinics, and expert resources across the Aloha State.
Hawaii & International Travel Health
Hawaii, the Aloha State, occupies a unique position as the only U.S. state located in the Pacific Ocean — a crossroads between North America and Asia-Pacific. Daniel K. Inouye International Airport (HNL) in Honolulu serves as a major hub for transpacific travel, with direct routes to Japan, South Korea, Australia, the Philippines, and dozens of Pacific Island nations. Honolulu is also a popular port of embarkation for cruises throughout the Pacific, Southeast Asia, and beyond.
Hawaii's diverse population includes large communities of Japanese, Filipino, Chinese, Korean, Samoan, and Marshallese heritage, with many residents maintaining close ties to family in the Pacific and Asia — making VFR (visiting friends and relatives) travel a significant portion of international departures from the islands. This guide brings together the most important travel-health information for Hawaii residents preparing for international trips from HNL, OGG (Kahului, Maui), KOA (Kailua-Kona), or ITO (Hilo).
Healthcare in Hawaii for Travelers
Hawaii provides access to travel medicine through a network of private vaccine clinics, state public health services, university-affiliated medical centers, and Kaiser Permanente Hawaii — one of the state's dominant healthcare systems. Travelers can access yellow fever certification, typhoid, hepatitis A/B, Japanese encephalitis, rabies pre-exposure, malaria prophylaxis, and specialist pre-travel consultations primarily through Honolulu-based clinics, with limited services available on Maui and the Big Island.
Hawaii Department of Health
The Hawaii Department of Health (HDOH) Disease Outbreak Control Division oversees statewide immunization programs, school health requirements, and the Hawaii State Immunization System (HiSIS). The HDOH Immunization Branch can be reached at (808) 586-8300 (Oahu) or 1-800-933-4832 (Neighbor Islands).
Academic & University Medicine
The Queen's Medical Center — Hawaii's only Level I Trauma Center and largest academic hospital — provides infectious disease expertise and specialist travel health consultation. The University of Hawaii John A. Burns School of Medicine trains the state's physician workforce in tropical and Pacific medicine.
Private Travel Clinics
Passport Health operates multiple Oahu locations with the state's most comprehensive travel vaccine inventory, including yellow fever, Japanese encephalitis, typhoid, rabies, and malaria prescriptions. Additional services are available through Kaiser Permanente Hawaii (members) and Straub Medical Center Travel Clinic.
Vaccine Regulations in Hawaii
Hawaii vaccine regulations are governed by Hawaii Administrative Rules Title 11, Chapter 157 and administered by the Hawaii Department of Health. Here is what travelers — and parents of young travelers — need to understand.
School Entry Requirements
Under Hawaii law (HAR Title 11, Chapter 157), all students entering childcare, preschool, kindergarten, 7th grade, post-secondary school, or entering Hawaii schools for the first time must present proof of required immunizations and TB clearance. Required vaccines include DTaP, Polio, MMR, Varicella, Hepatitis B, and Meningococcal vaccines at specified grade levels. Hawaii also uniquely requires a tuberculosis (TB) clearance for all new school entrants.
Exemptions Permitted
Hawaii currently allows medical and religious exemptions from school vaccine requirements with appropriate documentation. During the 2023–2024 school year, Hawaii's religious exemption rate reached 4.07%, well above national averages — prompting legislative debate over HB1118 which would have removed non-medical exemptions. Parents must submit completed exemption forms to the school or childcare facility.
Entry Requirements for Hawaii
Hawaii has no general vaccine mandate for residents or visitors. However, rabies-free status is strictly protected — Hawaii enforces among the strictest animal import regulations in the world to preserve its rabies-free status. For international travelers departing Hawaii, destination-country vaccine requirements apply and should be confirmed via CDC and the destination's embassy.
Routine Vaccines for Children in Hawaii
Hawaii's childhood immunization schedule follows the CDC/ACIP recommended schedule. The HDOH Division of Disease Outbreak Control actively promotes adherence, noting that Hawaii's unique position as a Pacific crossroads exposes residents to diseases — including Japanese encephalitis, dengue fever, and enteric infections — that are uncommon on the US mainland but circulate widely in the countries Hawaii travelers visit most frequently.
| Vaccine | Disease(s) Prevented | Typical Schedule | Notes for Travelers |
|---|---|---|---|
| DTaP / Tdap | Diphtheria, Tetanus, Pertussis | 5 childhood doses; Tdap booster at 7th grade | Tdap especially important before travel to developing regions; pertussis outbreaks frequent in Asia |
| Polio (IPV) | Poliomyelitis | 4 doses by age 4–6 | Adult booster recommended for travel to Pakistan, Afghanistan, and some African countries |
| MMR | Measles, Mumps, Rubella | 2 doses: 12–15 months & 4–6 years | Measles is endemic across Asia and the Pacific; confirm 2 doses before any international travel |
| Varicella | Chickenpox | 2 doses: 12–15 months & 4–6 years | Required for Hawaii school entry; documented chickenpox history may substitute per HDOH |
| Hepatitis B | Hepatitis B virus | 3-dose series: birth, 1–2 months, 6–18 months | Critically important for the Philippines, China, Vietnam, and Pacific Island destinations with high HBV prevalence |
| Hib | Haemophilus influenzae type b | 3–4 doses by 15 months | Standard childhood protection; confirm completion before travel |
| PCV (Pneumococcal) | Pneumococcal disease, pneumonia | 4 doses by 15 months | Protects against pneumonia globally; particularly important for Pacific Island travel |
| Hepatitis A | Hepatitis A virus | 2 doses starting at 12–23 months | High priority for Japan, Philippines, Southeast Asia, and Pacific Island travel |
| MenACWY (Meningococcal) | Meningococcal disease A, C, W, Y | 11–12 years; booster at 16; required at 7th grade in Hawaii | Required for Saudi Arabia (Hajj/Umrah) and recommended for sub-Saharan Africa travel |
| Rotavirus | Severe diarrheal disease | 2–3 doses by 8 months | Particularly relevant for travel to developing countries in Asia and the Pacific |
| HPV | Human Papillomavirus / cervical cancer | 2–3 doses starting at age 11–12 | Routine preventive care; stay on schedule despite travel disruption |
| Influenza | Seasonal influenza | Annually from 6 months of age | Influenza circulates year-round in the tropics; timing differs in the Southern Hemisphere |
| COVID-19 | COVID-19 | From 6 months; updated annually | 2024–2025 updated vaccine recommended by CDC; some Asia-Pacific destinations may require documentation |
Routine Vaccines for Adults in Hawaii
Adult travelers departing Hawaii should ensure routine vaccinations are current before adding travel-specific vaccines. The following core vaccines are recommended for all Hawaii adults as a baseline before any international trip.
Tdap / Tetanus Booster
Every 10 years. Essential before travel to destinations with limited emergency medical care or wound treatment access — particularly rural Asia and Pacific islands.
Influenza (Annual)
Year-round protection essential for Pacific travel. Influenza strains circulate continuously in the tropics and the Southern Hemisphere flu season runs April–September — opposite to the US.
COVID-19 (Updated Annually)
Stay current with updated annual boosters before international travel. Some Asia-Pacific destinations may still require proof of vaccination or recent testing for entry.
Hepatitis A & B
Both strongly recommended for all Asia-Pacific destinations. Twinrix combines Hep A and B in a single series. Hepatitis B prevalence is very high across the Philippines, China, Vietnam, Korea, and Pacific Island nations.
Meningococcal (MenACWY)
Required for Saudi Arabia (Hajj/Umrah) and recommended for sub-Saharan Africa travel. Hawaii's large Muslim community and frequent religious travel make this particularly relevant.
Shingles (Shingrix)
Recommended for adults 50+. Two-dose series, given 2–6 months apart. Plan timing well in advance of travel — the second dose cannot be rushed.
