San Antonio, TX: Your Gateway to International Travel Health
A complete guide for San Antonio-based travelers preparing for international trips — vaccines, regulations, clinics, and expert resources across Bexar County and South Texas.
San Antonio & International Travel Health
San Antonio is Texas's second-largest city and one of the most culturally distinctive in the United States — with a Mexican heritage dating back centuries, a majority Latino population, and the largest concentration of U.S. military installations of any American city. Joint Base San Antonio encompasses Fort Sam Houston, Lackland Air Force Base, and Randolph Air Force Base, generating an enormous and constant flow of military personnel and their families traveling worldwide. San Antonio International Airport (SAT) and the proximity to the U.S.-Mexico border make it one of the Southwest's most internationally connected cities.
Bexar County and the greater San Antonio region offer strong access to travel health services through UT Health San Antonio, the University Health system, Methodist Hospital, multiple Passport Health clinics, the Metro Health San Antonio Department, and the military's medical infrastructure at Brooke Army Medical Center (BAMC) at Fort Sam Houston.
Healthcare in San Antonio for Travelers
San Antonio's healthcare ecosystem is anchored by UT Health San Antonio, University Health (the county's public academic medical center), the Methodist Hospital system, and Brooke Army Medical Center — one of the military's premier medical facilities. Travelers can access pre-travel consultations, full vaccine menus, malaria prescriptions, destination-specific counseling, and post-travel assessment through Passport Health, Metro Health, University Health, and UT Health San Antonio's infectious disease services.
State Health Authority
The Texas Department of State Health Services (DSHS) oversees immunization policy statewide. Metro Health San Antonio — the city-county health authority — delivers local immunization programs, yellow fever vaccination services, and community health services for Bexar County residents.
Academic & Military Medicine
UT Health San Antonio and University Health offer specialist-level infectious disease services and travel medicine evaluation. Brooke Army Medical Center (BAMC) at Fort Sam Houston provides travel medicine and infectious disease services for active-duty military, veterans, and their eligible families.

Vaccine Regulations in Texas
School Entry Requirements
Children in San Antonio — including San Antonio ISD, Northside ISD, and other Bexar County school districts — must receive required immunizations including DTaP/Tdap, polio, MMR, hepatitis B, varicella, and meningococcal vaccine per Texas law and DSHS schedules. Texas uses the ImmTrac2 immunization registry.
Exemptions
Texas allows medical and conscientious exemptions from school immunization requirements. Medical exemptions require physician documentation. Conscientious exemptions require a notarized affidavit submitted to the school as required by Texas state law.
International Travel Rules
Texas does not require residents to be vaccinated before leaving the state, but many countries require or strongly recommend specific vaccines. Given San Antonio's majority Latino population and proximity to Mexico, as well as its large military community, hepatitis A, typhoid, and yellow fever are among the most commonly discussed travel vaccines.
Routine Vaccines for Children in San Antonio
San Antonio follows Texas's nationally recommended childhood and adolescent immunization schedules. For travel medicine, San Antonio's majority Latino community generates enormous VFR travel to Mexico, Guatemala, El Salvador, Honduras, and Colombia — all destinations where hepatitis A, typhoid, and malaria prophylaxis (for Central American destinations) are commonly recommended. The city's military community also travels globally for deployments and family relocations.
| Vaccine | Disease(s) Prevented | Typical Schedule | Notes for Travelers |
|---|---|---|---|
| DTaP / Tdap | Diphtheria, Tetanus, Pertussis | 5 childhood doses; adolescent Tdap booster | Important for wound and respiratory protection during international travel |

Routine Vaccines for Adults in San Antonio
Adult travelers should not assume childhood immunizations remain sufficient for life. San Antonio travel clinics review tetanus, influenza, COVID-19, hepatitis A and B, shingles, pneumococcal vaccination, and destination-linked concerns. San Antonio's majority Latino community visiting Mexico and Central America, and its massive military population traveling globally, create year-round demand for travel health services across a very wide range of destinations.
Td / Tdap Booster
Adults should stay current with tetanus-containing boosters, generally every 10 years. Travel injuries, trekking, rural exposure, and minor wound care abroad all make this review important.
Every 10 yearsInfluenza
Annual flu vaccination remains a key routine recommendation. Travelers crossing hemispheres or traveling during regional flu season should review timing carefully.
AnnualCOVID-19
COVID-19 vaccination recommendations are updated over time. San Antonio travelers should confirm the current CDC age/risk guidance and any destination-specific documentation requirements.
Current guidanceHepatitis A & B
Travel clinics frequently prioritize hepatitis A and B for adults who were never vaccinated or have incomplete records. Especially relevant for travelers visiting Mexico, Central America, Colombia, and other Latin American destinations.
Catch-upMeningococcal
Required for Hajj/Umrah and recommended for travelers to Africa's meningitis belt and certain higher-risk adults. Important for military personnel traveling to sub-Saharan Africa deployments.
Risk-basedPneumococcal & Shingles
Older adults and those with certain conditions may need pneumococcal vaccination and shingles protection. Travel is a good time to update general preventive care.
