Wyoming: Your Gateway to International Travel Health
A complete guide for Wyoming-based travelers preparing for international trips — vaccines, regulations, clinics, and expert resources across the Equality State, from Cheyenne's high plains to Jackson Hole's world-stage resort and the Powder River Basin's energy frontier.
Wyoming & International Travel Health
Wyoming — the Equality State — is the least populous state in the United States and the tenth largest by land area, a vast high-plains and mountain landscape stretching from the Cheyenne high country in the southeast to the Bighorn Basin in the northwest, and from the Powder River Basin's energy fields in the northeast to the Bridger-Teton wilderness and the internationally celebrated resort of Jackson Hole in the west. With just under 600,000 residents spread across 97,000 square miles — roughly the size of the United Kingdom — Wyoming presents a unique travel health challenge: a geographically enormous state with limited in-state healthcare infrastructure, where residents regularly travel hundreds of miles for specialized medical care and where international travel typically routes through the major airports of neighboring states.
Wyoming residents traveling internationally almost universally depart from outside the state — most commonly through Denver International Airport (DEN) in Colorado, approximately 100 miles south of Cheyenne; Salt Lake City International Airport (SLC) in Utah, approximately 170 miles southwest of Rock Springs; or Billings Logan International Airport (BIL) in Montana, accessible from Sheridan. Within Wyoming, the principal in-state departure points include Jackson Hole Airport (JAC) — the only commercial airport within a US National Park, serving Jackson's internationally connected resort community — and Casper/Natrona County International Airport (CPR). Medically, Wyoming is anchored by Wyoming Medical Center in Casper (the state's only Level II Trauma Center with a full-service hospital program) and Cheyenne Regional Medical Center in the state capital. For the most complex travel health preparation needs, Wyoming residents benefit from geographic proximity to world-class academic medical resources in Denver — UCHealth University of Colorado Hospital and National Jewish Health — accessible in two to three hours from Cheyenne.
Healthcare in Wyoming for Travelers
Wyoming's travel health landscape reflects the honest realities of its geography: a vast, sparsely populated state where healthcare resources are more limited than any other in the continental US, but where dedicated regional hospitals, WDH county health departments, and strategic proximity to major medical centers in Denver and Salt Lake City together provide Wyoming residents with access to the pre-travel preparation they need. Wyoming Medical Center in Casper and Cheyenne Regional Medical Center are the state's most capable in-state facilities for travel health. St. John's Medical Center in Jackson serves Wyoming's most internationally connected resort community. The Wyoming Department of Health (WDH) Immunization Program maintains the Wyoming Immunization Registry (WyIR) and coordinates immunization services through county health departments across all 23 Wyoming counties.
State Health Authority
The Wyoming Department of Health (WDH) Immunization Program oversees vaccine policy, maintains the Wyoming Immunization Registry (WyIR), and coordinates Yellow Fever Vaccination Center certification statewide. School immunization requirements are governed by Wyoming Statute § 21-4-309 and WDH Rules and Regulations Chapter 3. WDH operates county and district public health offices across all 23 Wyoming counties.
Regional Hospital Programs
Wyoming Medical Center in Casper — Wyoming's most capable full-service hospital — and Cheyenne Regional Medical Center in the state capital provide Wyoming's primary in-state infectious disease and travel health consultation services. St. John's Medical Center in Jackson serves the internationally mobile Jackson Hole resort community. WDH county health offices supplement immunization access statewide across Wyoming's 23 counties.
Denver & Salt Lake City Access
For Wyoming residents requiring the most comprehensive travel medicine consultations — rare specialty vaccines (Japanese Encephalitis, rabies pre-exposure series), complex multi-country itineraries, or immunocompromising conditions — UCHealth University of Colorado (Denver) and University of Utah Health (Salt Lake City) are both accessible within 2–3 hours from most Wyoming population centers and offer full academic travel medicine programs.
Vaccine Regulations in Wyoming
Wyoming's school immunization requirements are governed by Wyoming Statute § 21-4-309 and WDH Rules and Regulations Chapter 3. Here is what travelers — and parents of young travelers — need to understand about the Equality State's vaccine framework.
School Entry Requirements
Under Wyoming Statute § 21-4-309, children attending any public or private school must present proof of required immunizations or a valid exemption. Required vaccines include DTaP/Tdap, Polio, MMR, Varicella, Hepatitis B, and MenACWY for secondary school entry. The WyIR (Wyoming Immunization Registry) tracks and verifies records statewide. WDH county health offices and school districts coordinate annual compliance reporting.
Exemptions Permitted
Wyoming grants exemptions on medical and religious grounds under Wyoming Statute § 21-4-309. Medical exemptions require documentation from a licensed Wyoming physician or APRN. Religious exemptions require a written statement from the parent or guardian affirming a sincere religious belief objection to immunization, submitted to the school. Wyoming's small-state public health infrastructure means that WDH monitors exemption patterns closely in the context of outbreak risk across the state's widely dispersed communities.
International Entry Requirements
Wyoming does not impose vaccine mandates for residents traveling internationally beyond school and childcare settings. However, destination countries enforce independent legally binding entry conditions. Yellow fever certification is required for many sub-Saharan African and South American destinations. Wyoming's energy sector workforce — particularly in the Powder River Basin and Pinedale Anticline gas fields — includes professionals who travel internationally to energy-producing regions in the Middle East, Africa, and Southeast Asia, for whom robust pre-travel preparation is essential.
Routine Vaccines for Children in Wyoming
Wyoming's childhood immunization schedule follows the CDC/ACIP recommended schedule. The WDH Immunization Program partners with pediatric providers statewide — anchored by Wyoming Medical Center's pediatric services in Casper and Cheyenne Regional Medical Center's pediatric program — to promote on-schedule vaccination across Wyoming's widely dispersed communities, from the agricultural communities of the Bighorn Basin to the ski resort families of Teton County and the ranching families of Goshen and Niobrara counties.
| Vaccine | Disease(s) Prevented | Typical Schedule | Notes for Travelers |
|---|---|---|---|
| DTaP / Tdap | Diphtheria, Tetanus, Pertussis | 5 doses by age 6; Tdap booster at 11–12 | Tetanus wound exposure risk is elevated in outdoor adventure, ranching, and remote international settings — confirm current status before departure |
| Polio (IPV) | Poliomyelitis | 4 doses by age 4–6 | Some countries require proof of polio vaccination for exit — Africa and South Asia travel |
| MMR | Measles, Mumps, Rubella | 2 doses: 12–15 months & 4–6 years | Measles is endemic globally; confirm 2 documented doses before any international trip — Jackson Hole's international tourism community means measles exposure is closer than it appears |
| Varicella | Chickenpox | 2 doses: 12–15 months & 4–6 years | Required for WY school entry; immunity critical across all international travel settings |
| Hepatitis B | Hepatitis B virus | 3-dose series: birth, 1–2 months, 6–18 months | Critical for travel to Asia, Africa, and Eastern Europe — important for Wyoming energy sector workers in international postings |
| Hepatitis A | Hepatitis A virus | 2 doses starting at 12–23 months | Essential for travel to Mexico, Latin America, and all developing-country destinations; Wyoming families visiting Mexico or Central America should confirm children are current |
| Hib | Haemophilus influenzae type b | 3–4 doses by 15 months | Standard childhood protection; confirm up to date before international travel |
| PCV (Pneumococcal) | Pneumococcal disease, pneumonia | 4 doses by 15 months | Protects against serious pneumonia complications globally — important for all international travel itineraries |
| Rotavirus | Severe diarrheal disease | 2–3 doses by 8 months | Relevant for Wyoming families traveling to developing countries with limited clean water access |
| MenACWY (Meningococcal) | Meningococcal disease A, C, W, Y | 11–12 years; booster at 16 — required at WY secondary school entry | Required for sub-Saharan Africa travel and Saudi Arabia (Hajj/Umrah pilgrimage) |
| HPV | Human Papillomavirus / cervical cancer | 2–3 doses starting at age 11–12 | Maintain on-schedule vaccination regardless of travel; recommended through age 26 |
| Influenza | Seasonal influenza | Annually from 6 months of age | Southern Hemisphere flu season (April–September) is relevant for Mexico, Latin American, and Southern Hemisphere destination travel |
| COVID-19 | COVID-19 | From 6 months; updated annually | 2024–2025 updated vaccine recommended by CDC; confirm any destination entry documentation requirements before departure |

Adult vaccine protection from childhood series can fade significantly over time, and adults face unique health risks based on specific travel destinations and activities. The WDH and CDC recommend all Wyoming adults review and update the following vaccines — particularly before any international trip through Denver, Salt Lake City, Jackson Hole, or Casper airports.
Td / Tdap Booster
Every adult should receive a Td booster every 10 years. Adults who never received Tdap should substitute one Td dose with Tdap. For Wyoming's ranching, agricultural, and outdoor adventure communities — where tetanus exposure from soil, animal contact, and puncture wounds is a real occupational and recreational reality — maintaining a current Tdap is a baseline health priority before international travel to any destination.
Every 10 yearsInfluenza (Annual)
Annual flu vaccination is recommended for all Wyoming adults. The updated 2024–2025 vaccine is available at pharmacies, WDH county health offices, and hospital systems statewide. Southern Hemisphere flu season (April–September) is particularly relevant for Wyoming travelers departing in late spring or summer — which represents a peak travel season for Wyoming residents heading to Mexico, the Caribbean, and international destinations via Denver or Salt Lake City.
AnnualCOVID-19 (Updated)
The 2024–2025 updated COVID-19 vaccine is recommended for all Wyoming adults. Available at pharmacies, WDH county health offices, and hospital systems statewide. Some international destinations still require documentation of vaccination status for entry or transit — confirm your destination's current policy well before departure through DEN, SLC, or JAC.
Updated annuallyHepatitis A & B
Adults not vaccinated in childhood should complete both series before international travel. Hepatitis A is essential for Mexico, Central America, and all developing-country destinations — Wyoming families with ranch hands, seasonal workers, and Hispanic community members traveling to Mexico and Central America should ensure both they and their travel companions are protected. Hepatitis B is high priority for Asia, Africa, and energy-sector international postings.
Catch-up seriesMeningococcal
MenACWY is required for Hajj/Umrah pilgrimage to Saudi Arabia and strongly recommended for sub-Saharan Africa travel. MenB is recommended for college students and adults at increased risk — University of Wyoming students preparing for study abroad programs should confirm both MenACWY and MenB status before international departure. Both vaccines are available at Wyoming Medical Center, Cheyenne Regional, and UW Student Health.
Risk-basedPneumococcal & Shingles
Adults 50 and older should receive Shingrix (shingles vaccine) as a 2-dose series. PCV15 or PCV20 is recommended for adults 65+ and younger adults with specific health conditions. Wyoming's substantial rancher, retiree, and outdoor recreation communities should ensure both vaccines are current before long-haul international travel to destinations far from Wyoming's already limited in-state healthcare resources.
Age 50+The Three Categories of Travel Vaccines
Travel vaccines fall into three distinct categories. Understanding each is essential for any Wyoming traveler preparing for an international trip. Your travel health provider — whether at Wyoming Medical Center, Cheyenne Regional, St. John's Jackson, UW Student Health, or a Denver/SLC academic travel medicine program — will assess all three during your pre-travel consultation.
| Travel Vaccine | Category | Key Destinations | Notes |
|---|---|---|---|
| Yellow Fever | Required | Sub-Saharan Africa, tropical South America | Wyoming Medical Center (Casper) and Cheyenne Regional Medical Center are Wyoming's primary in-state CDC-certified YF centers; Denver Passport Health and UCHealth are also strong options |
| Typhoid | Recommended | South Asia, Southeast Asia, Africa, Mexico, Latin America | Oral or injectable; available at Wyoming Medical Center, Cheyenne Regional, and WDH health offices — confirm availability when booking |
| Japanese Encephalitis | Recommended | Rural Asia, Southeast Asia | 2-dose series; likely requires Denver (UCHealth) or Salt Lake City (U of Utah Health) for reliable access — plan travel medicine visit around DEN or SLC departure |
| Rabies (pre-exposure) | Recommended | Asia, Africa, Latin America (remote areas) | 3-dose series; advisable for Wyoming adventure travelers, ranchers traveling internationally, missionaries, and wildlife or veterinary professionals — plan for Denver or SLC access |
| Cholera (Vaxchora) | Recommended | Sub-Saharan Africa, South/Southeast Asia, Haiti | Single oral dose for adults; likely requires Denver or SLC travel clinic for reliable access — confirm with Wyoming Medical Center or Cheyenne Regional when scheduling |
| Meningococcal ACWY | Required / Recommended | Meningitis Belt (Africa), Saudi Arabia (Hajj/Umrah) | Required for Hajj; available at Wyoming Medical Center, Cheyenne Regional, UW Student Health, and WDH county health offices |
| Hepatitis A | Recommended | Mexico, Latin America, developing countries worldwide | Widely available statewide at WDH county health offices and major hospitals — one of the most important vaccines for Wyoming residents traveling to Mexico and Latin America |
| Malaria Prophylaxis | Prescription Rx | Sub-Saharan Africa, South/Southeast Asia, Central America | Not a vaccine — prescription medication available from Wyoming Medical Center, Cheyenne Regional, and WDH providers; Denver and SLC travel medicine programs also reliable sources |
Main Travel Health & Vaccine Centers in Wyoming
Wyoming's travel health resources are organized around the state's five primary population centers — Cheyenne, Casper, Jackson, Laramie, and Sheridan — supplemented by WDH county health offices across all 23 counties. For specialty vaccines and complex itineraries, Denver and Salt Lake City travel medicine programs are the recommended out-of-state resources for Wyoming residents.
Casper / Central Wyoming
1233 E 2nd St, Casper, WY 82601
(307) 577-7201 | By appointment
Wyoming Medical Center — the state's largest and most capable full-service hospital, serving as Wyoming's de facto Level II Trauma flagship in Casper — provides the most comprehensive in-state travel health program available within Wyoming's borders. WMC's infectious disease and primary care specialists offer pre-travel consultations, yellow fever certification, essential travel vaccines, and malaria prophylaxis prescriptions. As Wyoming's geographic hub — approximately equidistant from Cheyenne, Sheridan, and Rock Springs — Wyoming Medical Center is the natural first-call travel health resource for residents of Central, North-Central, and Western Wyoming. The hospital serves an energy sector workforce community whose international exposure encompasses the Middle East, Africa, and Latin America's oil and gas producing regions.
Cheyenne / Southeast Wyoming
214 E 23rd St, Cheyenne, WY 82001
(307) 634-2273 | By appointment
Cheyenne Regional Medical Center — Wyoming's state capital hospital and Southeast Wyoming's Level II Trauma Center — provides travel immunization and infectious disease services for Laramie County and the surrounding Southeast Wyoming communities. Cheyenne's unique position — just 100 miles north of Denver on I-25 — means that Southeast Wyoming residents have the most convenient in-state travel medicine access in the state AND the shortest drive to Denver's world-class travel medicine programs at UCHealth University of Colorado Hospital or Denver Health. F.E. Warren Air Force Base — home to the 90th Missile Wing and a major Air Force installation adjacent to Cheyenne — creates a significant military community with international travel health needs that CRMC supports as the primary civilian hospital in the area.
100 Central Ave, Cheyenne, WY 82001 | (307) 633-4000
WDH Laramie County Public Health provides travel immunization services at affordable public health pricing for Cheyenne-area residents. An accessible resource for uninsured or underinsured Wyoming travelers. Contact directly for appointment scheduling and to confirm which travel vaccines are available at the county health office level.
Jackson Hole / Teton County
625 E Broadway, Jackson, WY 83001
(307) 733-3636 | By appointment
St. John's Medical Center — Teton County's primary hospital and Wyoming's most internationally connected community hospital — provides travel immunization and clinical services for the Jackson Hole resort and adventure community. Jackson Hole is arguably Wyoming's most internationally oriented community: a world-class ski and outdoor adventure destination that attracts international visitors year-round and whose permanent and seasonal resident population includes a substantial international workforce, wealthy international homeowners, global business executives, and adventure athletes traveling across multiple continents for skiing, trekking, climbing, and wildlife expeditions. Contact directly to confirm available travel vaccines and scheduling. Jackson Hole's proximity to Idaho Falls (90 miles) and Salt Lake City (300 miles) also provides access to larger regional travel medicine programs for complex consultations.
Laramie / University of Wyoming
1000 E University Ave, Laramie, WY 82071
(307) 766-2130 | By appointment
University of Wyoming Student Health Services provides travel immunization services for the UW Laramie campus community. The University of Wyoming — Wyoming's only four-year university — has active study abroad programs and international research partnerships, creating consistent demand for travel health preparation among students, faculty, and staff departing for global destinations. UW students and faculty undertaking fieldwork in Africa, Latin America, or Asia should contact Student Health well in advance — and consider supplementing with a Denver travel medicine consultation for rare vaccines or complex itineraries, as Cheyenne and Denver are both accessible within 50–100 miles of Laramie.
Sheridan & Northeast Wyoming / Powder River Basin
1401 W 5th St, Sheridan, WY 82801
(307) 672-1000 | By appointment
Sheridan Memorial Hospital is Northeast Wyoming's primary regional hospital, serving Sheridan, Johnson County, and the communities of the northern Bighorn Basin and Powder River Basin. Travel immunization services are available through Sheridan Memorial's clinical programs. Northeast Wyoming residents — including Gillette's energy sector workforce at Campbell County Health — should contact both Sheridan Memorial and Wyoming Medical Center in Casper for travel vaccine availability. For complex travel medicine consultations, Sheridan's proximity to Billings, Montana (approximately 130 miles north) gives Northeast Wyoming residents access to Billings Clinic and St. Vincent Healthcare's travel health services as a regional alternative to the Denver or SLC options available to Southern Wyoming residents.
Pre-Travel Health Checklist for Wyoming Travelers
Follow this step-by-step timeline — tailored to Wyoming's unique geographic realities — to ensure you are fully protected before departing on an international trip, whether routing through Denver, Salt Lake City, Jackson Hole, or Casper.
| Timeframe | Action | Details |
|---|---|---|
| 6–8 Weeks Before | Book your travel health consultation | Contact Wyoming Medical Center (Casper), Cheyenne Regional (Cheyenne), St. John's (Jackson), UW Student Health (Laramie), or Sheridan Memorial (Sheridan). Or — strategically — book with UCHealth Travel Medicine (Denver) or University of Utah Health Travel Medicine (SLC) and combine with your international departure trip. Research destination requirements at CDC Travelers' Health. Wyoming residents should allow the extra 2 weeks of lead time given potential in-state appointment scheduling constraints. |
| At Your Visit | Bring your vaccination records | Receive required and recommended vaccines for your destination. Get prescriptions for malaria prophylaxis if needed. Request your ICVP Yellow Card if yellow fever vaccination is legally required. Ask your provider to review your WyIR records to identify any gaps in your adult vaccination history. If visiting Denver or SLC for your consultation, confirm in advance that your chosen travel clinic can source all vaccines you need — particularly specialty vaccines like Japanese Encephalitis. |
| Follow-Up Visits | Complete multi-dose series | Rabies pre-exposure (3 doses over 21 days), Japanese Encephalitis (2 doses), Hepatitis A catch-up (2 doses), and Hepatitis B (3 doses) require multiple appointments spaced weeks apart. For Wyoming residents using Denver or SLC travel medicine programs, discuss whether any doses can be completed at in-state facilities between visits to reduce long-distance travel. Wyoming Medical Center and Cheyenne Regional can administer follow-up doses with a prescription from a Denver provider. |
| 1–2 Weeks Before | Confirm all travel health documents | Verify your ICVP (Yellow Card) is correctly stamped, signed, and dated by a registered center. Pack a travel health kit: oral rehydration salts, antidiarrheal medication, DEET insect repellent (30%+), sunscreen, and all prescription medications including malaria prophylaxis. For Wyoming travelers driving to Denver or SLC to catch international flights, confirm your overnight and transit plan and ensure all documents are in order before the drive. |
| On Return | Monitor for illness symptoms | If you develop fever, rash, persistent diarrhea, jaundice, or unusual symptoms within weeks of returning to Wyoming, contact Wyoming Medical Center Infectious Disease (Casper) or Cheyenne Regional Medical Center (Cheyenne) immediately. For serious or complex post-travel illness — particularly tropical infections from Africa or Southeast Asia — UCHealth University of Colorado Hospital Infectious Disease in Denver is the most capable regional resource and is accessible from Cheyenne in under 2 hours. Always provide your complete travel history to every healthcare provider you contact. |
