San Diego, CA: Your Gateway to International Travel Health
A complete guide for San Diego-based travelers preparing for international trips — vaccines, regulations, clinics, and expert resources across San Diego County and beyond.
San Diego & International Travel Health
San Diego is California's second-largest city, the eighth-largest in the United States, and one of the most internationally distinctive cities in the country. Sharing a border with Tijuana, Mexico — making it part of the largest binational metropolitan region in the world — San Diego has a large Latino population with deep cross-border ties, a significant Filipino community, a major military presence across all branches, and a growing Somali, Vietnamese, and South Asian population. San Diego International Airport (SAN) and the U.S.-Mexico border crossing at San Ysidro are among the busiest international crossing points in the world.
San Diego County offers outstanding access to travel health services through UC San Diego Health, Sharp Healthcare, Scripps Health, multiple Passport Health clinics, and the County of San Diego Health and Human Services Agency. The city's military presence — including Naval Base San Diego, Marine Corps Base Camp Pendleton, and Miramar Marine Corps Air Station — also contributes significant military travel medicine infrastructure. This guide brings together the essential travel-health information San Diego travelers need before heading overseas.
Healthcare in San Diego for Travelers
San Diego's healthcare ecosystem is anchored by UC San Diego Health — one of the nation's top academic medical centers with a globally recognized infectious disease and global health program — alongside Sharp Healthcare, Scripps Health, and military medical facilities. Travelers can access pre-travel consultations, full vaccine menus, malaria prescriptions, tropical disease expertise, and post-travel assessment through UC San Diego, Passport Health, the County of San Diego HHSA, and military medical facilities for eligible personnel.
State Health Authority
The California Department of Public Health (CDPH) oversees immunization policy statewide and certifies authorized yellow fever stamp holders. The County of San Diego Health and Human Services Agency (HHSA) delivers local immunization programs and community health services for San Diego County's diverse population.
World-Class Academic Travel Medicine
UC San Diego Health — part of UC San Diego's Division of Infectious Diseases and Global Public Health — offers one of the nation's most respected travel medicine and global health programs. UCSD's program is exceptional for complex itineraries, tropical disease expertise, and post-travel illness assessment, particularly for travelers crossing between the U.S. and Mexico and for those visiting challenging global destinations.
Private Travel Clinics
Passport Health operates multiple clinics across San Diego County offering yellow fever, typhoid, rabies, hepatitis A/B, Japanese encephalitis, meningococcal, and additional travel vaccines with flexible scheduling. Sharp Healthcare and Scripps Health also provide travel vaccine and infectious disease services.
Vaccine Regulations in California
School Entry Requirements
Children in San Diego County — including San Diego Unified and other school districts — must receive required immunizations including DTaP/Tdap, polio, MMR, hepatitis B, and varicella per California law. California has one of the most comprehensive school immunization frameworks in the nation.
Medical Exemptions Only
California does not allow new personal-belief exemptions — only medical exemptions are permitted. Medical exemptions must be issued through the CAIR-ME system by a California-licensed MD or DO. This gives San Diego children a strong routine immunization baseline.
International Travel Rules
California does not require residents to be vaccinated before leaving the state. However, the proximity to Mexico means that San Diego health officials track cross-border disease dynamics closely. The County HHSA maintains close situational awareness with Baja California's health authorities for binational health issues.
Routine Vaccines for Children in San Diego
San Diego follows California's nationally recommended childhood and adolescent immunization schedules. California's medical-exemption-only policy gives San Diego children a strong routine baseline. For travel medicine, San Diego's binational character — the enormous volume of cross-border travel with Mexico — means hepatitis A and typhoid are practically front-of-mind for many San Diego families regardless of formal travel plans. Filipino families visiting the Philippines, Vietnamese families traveling to Vietnam, and Somali families visiting the Horn of Africa have additional specific vaccine needs.
| 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 |
| Polio (IPV) | Poliomyelitis | 4 doses in childhood | Some travelers to polio-affected areas may need an adult booster before departure |
| MMR | Measles, Mumps, Rubella | 2 doses | Measles remains one of the most important routine vaccines for international travel; measles outbreaks have originated from Tijuana and Baja California |
| Varicella | Chickenpox | 2 doses | Important for children and teens without prior disease or vaccination history |
| Hepatitis B | Hepatitis B virus | 3-dose infant/childhood series | Essential baseline protection for travel, especially for longer stays or medical care abroad |
| Hepatitis A | Hepatitis A virus | 2 doses beginning at 12 months | Critically important given San Diego's binational character and cross-border travel to Baja California; also essential for Philippines, Vietnam, East Africa |
| Hib | Haemophilus influenzae type b | 3–4 doses | Important routine pediatric protection, especially for younger children |
| PCV | Pneumococcal disease | 4-dose series | Helps reduce severe bacterial disease risk during travel |
| Rotavirus | Severe diarrheal disease | 2–3 doses in infancy | Relevant for cross-border travel and travel to many international destinations |
| MenACWY | Meningococcal disease A, C, W, Y | 11–12 years; booster at 16 | Required for Hajj/Umrah; important for sub-Saharan Africa; relevant for Somali community and military travelers |
| HPV | Human papillomavirus | 2–3 doses beginning age 11–12 | Not travel-specific, but part of complete adolescent preventive care |
| Influenza | Seasonal influenza | Annually | Seasonality differs by region and hemisphere; timing matters for travel |
| COVID-19 | COVID-19 | According to current CDC age guidance | Destination policies can change; verify current rules before departure |
Routine Vaccines for Adults in San Diego
Adult travelers should not assume childhood immunizations remain sufficient for life. San Diego travel clinics review tetanus, influenza, COVID-19, hepatitis A and B, shingles, pneumococcal vaccination, and destination-linked concerns. San Diego's binational cross-border travel, Filipino and Vietnamese VFR communities, Somali refugee community, and military traveler population all create year-round demand for the full spectrum of travel vaccines.
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 Diego 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. Given San Diego's cross-border lifestyle, hepatitis A is among the most critical vaccines for the region's entire adult population.
Catch-upMeningococcal
Required for Hajj/Umrah and recommended for travelers to Africa's meningitis belt. Relevant for San Diego's Somali Muslim community and military deployments to sub-Saharan Africa.
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.
Age / risk basedThe Three Categories of Travel Vaccines
| Travel Vaccine | Category | Key Destinations | Notes |
|---|---|---|---|
| Yellow Fever | Required | Tropical Africa, parts of South America | Must be administered by a CDPH-authorized yellow fever stamp holder; certificate becomes valid after 10 days |
| Typhoid | Recommended | Mexico, Central America, Philippines, Vietnam, India, East Africa | Available as oral or injectable vaccine; very commonly recommended for San Diego's Latino, Filipino, and Vietnamese VFR traveler communities |
| Japanese Encephalitis | Recommended | Rural Philippines, Vietnam, and Southeast Asia broadly | Relevant for San Diego's Filipino and Vietnamese communities traveling to rural Southeast Asia |
| Rabies (pre-exposure) | Recommended | Philippines, Vietnam, East Africa, rural Mexico; remote itineraries | Important for animal contact risk and destinations with limited access to urgent post-exposure care |
| Cholera | Recommended | Selected high-risk destinations in East Africa and elsewhere | Used selectively; travelers to the Horn of Africa should discuss cholera risk with UCSD or Passport Health |
| Meningococcal ACWY | Required / Recommended | Saudi Arabia (Hajj/Umrah), Africa's meningitis belt, East Africa | Legal requirement for some pilgrims; important for San Diego's Somali community and military deployments |
| Hepatitis A | Recommended | Mexico and Baja California, Philippines, Vietnam, East Africa, and broadly across Latin America and Asia | Critically important for San Diego given the city's binational character and the enormous volume of cross-border travel. San Diego County has been affected by hepatitis A outbreaks linked to cross-border travel patterns. |
| Malaria Prophylaxis | Prescription Rx | Sub-Saharan Africa, Southeast Asia including Philippines and Vietnam, parts of Mexico and Central America | Not a vaccine; medication choice depends on region, resistance, duration, and medical history. UCSD's global health team provides expert guidance for complex destinations. |
