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.

 Plan Ahead: Travel medicine appointments should be booked 4–6 weeks before international departure. Japanese encephalitis vaccine requires two doses 28 days apart — essential for travel to rural Asia. Yellow fever certificates take 10 days to become valid after vaccination.

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.

 For International Travel from Hawaii: Travelers heading to Japan, South Korea, the Philippines, Indonesia, and Pacific Island nations should confirm current entry requirements carefully. Japan encephalitis is endemic across much of rural Asia. Yellow fever vaccination is required for entry into many African and South American countries. Always check the CDC Travelers' Health portal and the destination country's official health authority before booking.

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.

 School Entry Requirements: Children entering Kindergarten must have DTaP, Polio, MMR, Varicella, and Hepatitis B. Children entering 7th grade must additionally receive Tdap and MenACWY. All new school entrants (any grade) must also show TB clearance — a unique Hawaii requirement not applicable in most other states. These are the minimum legal requirements under HAR Title 11, Chapter 157.
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
 Parents of children behind on immunizations can contact the HDOH Immunization Branch at (808) 586-8300 (Oahu) or 1-800-933-4832 (Neighbor Islands) to access the Hawaii State Immunization System (HiSIS) and schedule catch-up vaccinations before international travel.

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.

Cholera / Traveler's Diarrhea Situational South Asia, Sub-Saharan Africa, Pacific Island outbreaks Dukoral oral vaccine offers partial TD protection; discuss with travel clinic for high-risk itineraries
Meningococcal Situational Sub-Saharan Africa, Saudi Arabia (Hajj/Umrah) MenACWY required for Saudi Arabia; MenB for high-risk travelers to meningitis belt
Malaria Prophylaxis Medication Papua New Guinea, Solomon Islands, Indonesia, sub-Saharan Africa, South Asia Prescription medication (atovaquone-proguanil, doxycycline, or mefloquine); discuss full itinerary at clinic — malaria risk varies significantly by island and region
 Hawaii Travelers to the Pacific Islands: Travelers visiting Micronesia, Samoa, Tonga, Fiji, Papua New Guinea, and the Solomon Islands face specific risks including dengue fever, typhoid, hepatitis A, malaria (PNG and Solomon Islands), and limited local medical infrastructure. A comprehensive travel clinic consultation is strongly recommended before any extended Pacific Island trip. Japanese encephalitis transmission has been documented in parts of the Pacific.
 After Your Trip: Many tropical diseases — including malaria, dengue fever, typhoid, and leptospirosis — can present days to weeks after returning to Hawaii. The Queen's Travel Medicine Clinic and GW/Straub infectious disease services maintain full laboratory access to detect and treat tropical diseases. If you feel unwell after international travel, do not wait. Always mention your destination, travel dates, and any freshwater exposure to any healthcare provider you consult. Note that Hawaii providers may have less familiarity with some Asian and Pacific tropical diseases than mainland specialists — ask for an infectious disease referral if your condition is not rapidly improving.
