San Francisco, CA: Your Gateway to International Travel Health
A complete guide for San Francisco-based travelers preparing for international trips — vaccines, regulations, clinics, and expert resources across the Bay Area and beyond.
San Francisco & International Travel Health
San Francisco is one of the world's most internationally connected cities — a Pacific gateway, a global technology and finance hub, and one of the most culturally diverse urban centers in the United States. Residents departing from San Francisco International Airport (SFO) — a major transpacific and transatlantic hub — as well as Oakland International Airport (OAK) and Mineta San José International Airport (SJC) travel continuously to Asia, Latin America, Europe, Africa, the Middle East, and the Pacific. For San Francisco travelers heading abroad, travel health preparation is a critical first step that should begin well before departure.
The Bay Area offers some of the most sophisticated travel health resources in the United States. San Francisco is home to the University of California San Francisco (UCSF) — one of the world's leading academic medical centers with internationally recognized infectious disease and global health programs — as well as dedicated travel medicine clinics, San Francisco Department of Public Health services, and California Department of Public Health-certified yellow fever providers. San Francisco's extraordinary diversity — with large Chinese, Filipino, Latino, South Asian, Southeast Asian, and Pacific Islander communities — alongside its status as a hub for international business travel, academic fieldwork, and NGO/humanitarian work, means the full spectrum of global travel health risks is highly relevant locally. This guide brings together the essential travel-health information San Francisco travelers need before heading overseas.
Healthcare in San Francisco for Travelers
San Francisco offers one of the most comprehensive travel-health ecosystems in the United States. Travelers can access pre-travel consultations, routine immunization review, malaria prescriptions, destination-specific vaccine counseling, and post-travel assessment through UCSF Health's world-renowned travel medicine program, San Francisco Department of Public Health (SFDPH) immunization clinics, dedicated private travel clinics, Zuckerberg San Francisco General Hospital, and major health systems including Dignity Health, Sutter Health, and UCSF Health. The city's status as a global hub means its travel medicine providers regularly handle complex itineraries spanning remote fieldwork, humanitarian missions, high-altitude trekking, and frequent-flyer business travel.
State Health Authority
The California Department of Public Health (CDPH) oversees immunization policy statewide and certifies authorized yellow fever "uniform stamp" holders who can administer the vaccine and validate the International Certificate of Vaccination or Prophylaxis (ICVP) for travelers departing from San Francisco and across California. The San Francisco Department of Public Health (SFDPH) administers local immunization and travel health services.
World-Class Academic Travel Medicine
UCSF Travel Clinic — part of the UCSF Division of Infectious Diseases and Geographic Medicine — is one of the premier travel medicine programs in the United States, offering comprehensive pre-travel consultations, destination-specific vaccine counseling, malaria prophylaxis, altitude medicine, post-travel illness evaluation, and care for complex itineraries including humanitarian and research fieldwork.
Private Travel Clinics
Passport Health operates clinics in San Francisco and throughout the Bay Area offering yellow fever, typhoid, rabies, hepatitis A/B, Japanese encephalitis, and additional travel vaccines with same-week appointments often available. Pharmacy-based immunization services through CVS, Walgreens, and Safeway locations throughout the city also provide routine and select travel vaccine access.
Vaccine Regulations in California
California has one of the most structured school immunization frameworks in the United States. For outbound travel from San Francisco, entry rules are set by the destination country rather than the state itself. California's primary role for travelers is certifying yellow fever providers and maintaining strong routine vaccination standards — particularly important in San Francisco given its role as an international port of entry and a city with historically high rates of international travel and return.
School Entry Requirements
Children in California — including those in San Francisco Unified School District (SFUSD) — must receive required immunizations to attend public and private schools and child-care facilities. Required vaccines include DTaP/Tdap, polio, MMR, hepatitis B, and varicella according to age and grade requirements. San Francisco has historically maintained high school vaccination coverage rates.
Medical Exemptions Only
California does not allow new personal-belief exemptions for school and child-care entry. New medical exemptions must be issued through CAIR-ME by a California-licensed MD or DO and must meet state criteria. California's strict exemption policy, reinforced after measles outbreaks, applies fully in San Francisco.
International Travel Rules
California does not require residents to be vaccinated before leaving the state, but many countries require or recommend specific vaccines. Yellow fever remains the classic legal requirement for entry to parts of tropical Africa and South America — highly relevant for San Francisco's large West African, Latin American, and South American communities, as well as the city's frequent business and NGO travelers.
Routine Vaccines for Children in San Francisco
San Francisco follows California's nationally recommended childhood and adolescent immunization schedules. For travel medicine, routine vaccines matter just as much as travel-specific shots. Measles, hepatitis A, typhoid, and Japanese encephalitis are among the most important travel-related risks for the many San Francisco families who travel frequently to China, the Philippines, Vietnam, Hong Kong, South Korea, Japan, India, Mexico, El Salvador, and beyond — including a substantial population of frequent transpacific travelers with deep family ties across Asia.
| 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; outbreaks occur throughout Asia and the Pacific — highly relevant for SF's transpacific travelers |
| 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 for travel; hepatitis B prevalence is high in many of the regions San Francisco residents visit most frequently, particularly East and Southeast Asia |
| Hepatitis A | Hepatitis A virus | 2 doses beginning at 12 months | High-priority vaccine for travel to Asia, Latin America, Africa, and the Middle East — all common travel corridors from San Francisco |
| 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 because diarrheal illnesses remain common in many travel destinations |
| MenACWY | Meningococcal disease A, C, W, Y | 11–12 years; booster at 16 | Required for Hajj/Umrah and important for parts of sub-Saharan Africa; relevant for San Francisco's Muslim community |
| 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; particularly important for San Francisco's frequent transpacific travelers during Asia's winter flu season |
| COVID-19 | COVID-19 | According to current CDC age guidance | Destination policies can change; verify current rules before departure — especially for East Asian destinations that may maintain their own requirements |
Routine Vaccines for Adults in San Francisco
Adult travelers should not assume childhood immunizations remain sufficient for life. San Francisco travel clinics — including UCSF's globally recognized program — typically review tetanus status, influenza, COVID-19, hepatitis A and B, shingles, pneumococcal vaccination, and destination-linked concerns such as Japanese encephalitis, typhoid, yellow fever, and meningococcal protection. San Francisco's large populations of frequent business travelers, humanitarian and NGO workers, academic researchers, and VFR travelers to Asia and Latin America make this one of the most travel-vaccine-active cities in the United States.
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. San Francisco travelers on frequent transpacific routes should pay particular attention to flu timing in their destination countries, especially for winter travel to East Asia.
AnnualCOVID-19
COVID-19 vaccination recommendations are updated over time. San Francisco travelers should confirm the current CDC age/risk guidance and any destination-specific documentation requirements, particularly for Asian markets that have varied in their policies.
Current guidanceHepatitis A & B
Travel clinics frequently prioritize hepatitis A and B for adults who were never vaccinated or have incomplete records. Extremely high priority for San Francisco travelers visiting China, Vietnam, the Philippines, India, Mexico, and Latin America — all major travel corridors from SFO.
Catch-upMeningococcal
Required for Hajj/Umrah and recommended for some travelers to Africa's meningitis belt, students in group settings, and certain higher-risk adults including NGO workers and academic researchers.
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
San Francisco travel clinics generally divide travel immunization planning into three practical groups: routine vaccines, vaccines required for legal entry, and vaccines recommended because of itinerary-specific risk.
| Travel Vaccine | Category | Key Destinations | Notes |
|---|---|---|---|
| Yellow Fever | Required | Tropical Africa, parts of South America | Must be administered by an authorized yellow fever stamp holder; certificate becomes valid after 10 days |
| Typhoid | Recommended | South Asia, Southeast Asia, East Africa, Latin America, Mexico | Available as oral or injectable vaccine; very high priority for San Francisco VFR travelers visiting India, the Philippines, Vietnam, and Mexico |
| Japanese Encephalitis | Recommended | Rural Asia and parts of Southeast Asia | Particularly relevant for San Francisco given the city's extraordinarily high volume of travel to Japan, China, Southeast Asia, and the Philippines — especially for longer stays or rural exposure |
| Rabies (pre-exposure) | Recommended | Asia, Africa, Latin America; remote itineraries | Important for animal contact risk and destinations with limited access to urgent post-exposure care; frequently recommended for SF's NGO and fieldwork travelers |
| Cholera | Recommended | Selected high-risk destinations | Used selectively depending on destination and humanitarian or outbreak-related travel |
| Meningococcal ACWY | Required / Recommended | Saudi Arabia (Hajj/Umrah), Africa's meningitis belt | Legal requirement for some pilgrims and an important risk-based vaccine elsewhere |
| Hepatitis A | Recommended | Asia, Latin America, Africa, and many low- and middle-income destinations | Among the most commonly recommended travel vaccines; extremely high priority for San Francisco VFR travelers given the city's Asia and Latin America travel corridors |
| Malaria Prophylaxis | Prescription Rx | Sub-Saharan Africa, South and Southeast Asia, parts of Latin America | Not a vaccine; medication choice depends on region, resistance, duration, and medical history |
