Montana: Your Gateway to International Travel Health
A complete guide for Montana-based travelers preparing for international trips — vaccines, regulations, clinics, and expert resources across the state.
Montana & International Travel Health
Montana, Big Sky Country, is the fourth-largest state in the United States by area — stretching from the Great Plains in the east to the majestic Rocky Mountains in the west, home to Glacier National Park, Yellowstone's northern gateway, and vibrant communities in Billings, Missoula, Bozeman, Great Falls, Helena, Kalispell, and Butte. Despite its wide-open geography, Montana residents travel internationally in significant numbers each year — for missions, business, education, family connections, and adventure — and proper travel health preparation is what makes every trip safe.
Whether you are departing from Billings Logan International Airport (BIL), Bozeman Yellowstone International Airport (BZN), Missoula Montana Airport (MSO), Great Falls International (GTF), Helena Regional Airport (HLN), or Glacier Park International (FCA), your travel health preparation starts at home in Montana. This guide covers vaccine regulations, routine immunization priorities, travel-specific vaccines, and the main clinics and hospitals providing expert travel medicine services across the state.
Healthcare in Montana for Travelers
Montana offers solid infrastructure for pre-travel healthcare preparation. The state is served by Billings Clinic — the state's largest health system — alongside SCL Health, Providence, Bozeman Health, Benefis, Logan Health, and a network of regional hospitals and public health offices that make it achievable for residents to access travel vaccinations and medical consultations before any international trip.
State Health Authority
The Montana Department of Public Health and Human Services (DPHHS) oversees immunization policy through its Immunization Program. It maintains the Montana Immunization Information System (MIIS) and coordinates yellow fever vaccination provider certification across the state under Montana Code Annotated § 20-5-403.
Regional Medical Centers
Billings Clinic — Montana's largest health system — and Providence St. Patrick Hospital in Missoula provide the state's most comprehensive infectious disease and travel medicine consultation services, supporting travelers with complex itineraries and post-travel illness evaluation.
Private Travel Clinics
Passport Health operates a CDC-certified travel vaccine clinic in the Billings area, providing yellow fever certification, typhoid, rabies, and destination-specific counseling for travelers across Eastern and Central Montana.
Vaccine Regulations in Montana
Montana's vaccine regulations are governed by Montana Code Annotated § 20-5-403 (school immunization law) and rules of the Montana Department of Public Health and Human Services. Here is what travelers — and parents of young travelers — need to understand.
School Entry Requirements
Under Montana law (MCA § 20-5-403), every child attending a public or private school must present proof of required immunizations or a valid exemption. Required vaccines include DTaP, Polio, MMR, Varicella, Hepatitis B, and MenACWY, with a Tdap booster required for 7th grade entry.
Exemptions Permitted
Montana grants exemptions for medical and non-medical (religious/philosophical) grounds. Non-medical exemptions require that a parent or guardian sign a written declaration and submit it to the school. Medical exemptions require a licensed physician's documentation. Both are accepted under Montana law.
No General Business Mandates
Montana law does not impose general vaccine mandates on businesses or the public. In fact, Montana enacted legislation in 2021 (HB 702) prohibiting discrimination based on vaccination status. For international travel, entry vaccine requirements are imposed by destination-country law, not Montana regulations.
Routine Vaccines for Children in Montana
Montana's childhood immunization schedule follows the CDC/ACIP (Advisory Committee on Immunization Practices) recommended schedule. The DPHHS Immunization Program actively promotes adherence to the schedule, noting that children under age 5 are especially vulnerable because their immune systems have not yet built adequate defenses against vaccine-preventable diseases.
| Vaccine | Disease(s) Prevented | Typical Schedule | Notes for Travelers |
|---|---|---|---|
| DTaP / Tdap | Diphtheria, Tetanus, Pertussis | 5 doses by age 6; Tdap booster at 11–12 | Pertussis cases are rising globally; confirm current status before travel |
| Polio (IPV) | Poliomyelitis | 4 doses by age 4–6 | Booster may be required for travel to polio-active countries |
| MMR | Measles, Mumps, Rubella | 2 doses: 12–15 months & 4–6 years | Measles is endemic in many travel destinations; confirm 2 doses |
| Varicella | Chickenpox | 2 doses: 12–15 months & 4–6 years | Required for Montana school entry; confirms protection abroad |
| Hepatitis B | Hepatitis B virus | 3-dose series: birth, 1–2 months, 6–18 months | Especially important for destinations with high HBV prevalence |
| Hib | Haemophilus influenzae type b | 3–4 doses by 15 months | Standard childhood protection; confirm up to date before travel |
| PCV (Pneumococcal) | Pneumococcal disease, pneumonia | 4 doses by 15 months | Protects against serious pneumonia complications globally |
| Rotavirus | Severe diarrheal disease | 2–3 doses by 8 months | Particularly relevant when traveling to developing countries |
| Hepatitis A | Hepatitis A virus | 2 doses starting at 12–23 months | High priority for travel to areas with poor sanitation |
| MenACWY (Meningococcal) | Meningococcal disease A, C, W, Y | 11–12 years; booster at 16 — required at 7th grade in MT | Required for travel to Africa's meningitis belt & Saudi Arabia (Hajj) |
| HPV | Human Papillomavirus / cervical cancer | 2–3 doses starting at age 11–12 | Routine preventive care should stay on schedule despite travel |
| Influenza | Seasonal influenza | Annually from 6 months of age | Flu seasons differ by hemisphere; timing matters for international travel |
| COVID-19 | COVID-19 | From 6 months; updated annually | 2024–2025 updated vaccine recommended by CDC; some countries may require documentation |

Vaccine protection from childhood series can wane over time, and adults face different risk profiles. The DPHHS and CDC recommend a range of vaccines for adults on a routine basis — especially important to review and update before any international trip.
Td / Tdap Booster
Every adult should receive a Td booster every 10 years. If not vaccinated with Tdap as an adolescent, one Tdap dose should replace a Td dose. Particularly important for travelers to developing countries where wound exposure is higher.
Every 10 yearsInfluenza (Annual)
The CDC recommends annual flu vaccination for all adults. The 2024–2025 updated vaccine is available at pharmacies and DPHHS health offices statewide. Flu seasons are reversed in the Southern Hemisphere — timing matters for international travel.
AnnualCOVID-19 (Updated)
The updated 2024–2025 COVID-19 vaccine is recommended for all adults 6 months and older. Available at pharmacies and county health departments across Montana. Some countries may still require documentation for entry or transit.
Updated annuallyHepatitis A & B
Adults not vaccinated in childhood should complete the Hepatitis A (2-dose) and Hepatitis B (3-dose) series. Both are high priority for international travelers, especially those visiting areas with poor sanitation or high HBV prevalence.
Catch-up seriesMeningococcal
MenACWY is recommended for adults at risk and required for travelers to the meningitis belt of Africa and for Hajj/Umrah in Saudi Arabia. MenB is recommended for adults at increased risk and some college-age travelers.
Risk-basedPneumococcal & Shingles
Adults 50+ should receive the shingles vaccine (Shingrix) as a 2-dose series. Pneumococcal vaccines (PCV15 or PCV20) are recommended for adults 65+ or younger adults with specific health conditions, providing protection against pneumonia globally.
Age 50+The Three Categories of Travel Vaccines
Travel vaccines fall into three distinct categories. Understanding the difference is essential when preparing for your trip from Montana. Your travel health provider will assess all three during your pre-travel consultation.
| Travel Vaccine | Category | Key Destinations | Notes |

| Cholera (Vaxchora) | Recommended | Sub-Saharan Africa, South/Southeast Asia, Haiti | Single oral dose for adults; confirm availability with your travel clinic |
| Meningococcal ACWY | Required / Recommended | Meningitis Belt (Africa), Saudi Arabia (Hajj/Umrah) | Required for Hajj; strongly recommended for sub-Saharan Africa travel |
| Hepatitis A | Recommended | Developing countries worldwide | High priority for most international destinations; 2-dose series |
| Malaria Prophylaxis | Prescription Rx | Sub-Saharan Africa, South/Southeast Asia, Central America | Not a vaccine — prescription medication available from Montana travel clinics |
