Travel Vaccines for Mexico
Hepatitis A, Dengue, Typhoid, and Travellers’ Diarrhea are real risks for Ottawa travellers heading to Mexico. Get a personalized vaccine plan before you go.
⚠️ Active Health Alert — Measles Outbreak (February 2026)
Mexico is currently experiencing a major measles outbreak with approximately 690 confirmed cases per week since mid-January 2026 — primarily in Jalisco State. Travellers born in 1970 or later (Canada) should confirm they have had 2 lifetime doses of MMR vaccine. Infants 6–11 months travelling to Mexico should receive an early MMR dose. Book a consultation to verify your status before departure.
⚠️ Influenza Update — 2025–26 Strain Mismatch (February 2026)
The 2025–26 influenza vaccine is poorly matched to the dominant A(H3N2) strain circulating this season (94% mismatch in Canada). Despite this, vaccination still provides meaningful protection — approximately 57% against clinical disease in adults. Travellers heading to Mexico should still get vaccinated and can discuss standby antiviral therapy (oseltamivir/baloxavir) during their consultation.
Recommended Vaccines for Mexico
Based on Travax clinical guidelines (updated February 2026). Your pharmacist will tailor recommendations to your itinerary, health history, and travel dates.
✅ All Travellers
- Hepatitis A — High risk throughout Mexico, including tourist and deluxe accommodations. Recommended for all travellers. Vaccine provides long-term protection; a single dose before travel is highly effective.
- COVID-19 — Risk exists year-round. Ensure you are current with your home country recommendations.
- Influenza — Peak October–April. Recommended for all travellers during transmission season. Note the 2025–26 A(H3N2) mismatch — vaccination is still advised.
- MMR (Measles) — Essential given the active 2026 measles outbreak in Mexico. Confirm 2-dose lifetime history. Born before 1957: generally immune. Born 1957–1970 in Canada: confirm 1 prior dose or disease history.
⚠️ Most Travellers
- Dengue — Significant risk in urban and rural areas throughout most of Mexico below 2,300 m elevation, including Cancún, Cozumel, Puerto Vallarta, Acapulco, Mazatlán, and Mérida. Vaccine (dengue vaccine) available for ages 4–60 years. Peak transmission May–November. Low risk in Mexico City.
- Typhoid Fever — Recommended for travellers with adventurous eating habits, stays over 1 month, or travel outside standard tourist routes and rural areas. Consider for all risk-averse travellers.
- Hepatitis B — Recommended for travellers at increased risk: those receiving medical or dental care abroad, those with multiple sexual partners, adventure travellers, and all long-stay travellers. Part of routine immunization for most Canadians — confirm your status.
🔵 Some Travellers
- Rabies — Recommended for animal workers, veterinarians, wildlife professionals, and anyone likely to encounter bats. Risk from domestic and wild animals exists especially along the Gulf Coast.
- Chikungunya — Low risk. Consider for travellers aged 12+ with prolonged stays of 6 months or more.
- Mpox — Recommended for high-risk persons or those with anticipated exposure.
- Yellow Fever (Entry Requirement) — Mexico does not require Yellow Fever vaccination for most travellers. However, proof of Yellow Fever vaccination is required by Mexico if you are arriving from a Yellow Fever-endemic country (e.g., many sub-Saharan African or South American countries). If your itinerary includes a stopover in an endemic area, discuss this during your consultation.
Travellers’ Diarrhea
Risk: High throughout Mexico — including deluxe accommodations. Community sanitation and food safety standards are generally inadequate. Risk is further elevated for travellers visiting remote destinations, eating street or market food, or participating in ecotourism.
Your pharmacist will advise you on strict food and water precautions and may prescribe a standby antibiotic (typically single-dose azithromycin) combined with loperamide for self-treatment. Hydrate with safe water and maintain electrolytes if you experience symptoms. Travellers with dysenteric symptoms (high fever, bloody stools) should use antibiotics alone and avoid loperamide.
Malaria in Mexico
Type: P. vivax only (not the more dangerous P. falciparum). Transmission is highest June–November.
Good news for most travellers: The vast majority of popular Mexican tourist destinations have no malaria risk — including Mexico City, Cancún, Cozumel, Riviera Maya, Puerto Vallarta, Los Cabos, Acapulco, Mazatlán, and all major archaeological sites.
Chemoprophylaxis is recommended only for travellers to specific rural municipalities in Chihuahua, Oaxaca, Chiapas, and Campeche states. If your itinerary includes these areas, your pharmacist will recommend appropriate medication (atovaquone-proguanil, chloroquine, doxycycline, mefloquine, or tafenoquine).
Destination Risk Snapshot
Risk varies significantly across Mexico. Here’s a quick comparison for common Ottawa traveller destinations:
| Destination | Dengue Risk | Malaria Risk | Key Notes |
|---|---|---|---|
| Cancún / Riviera Maya | Significant (May–Nov) | None | Dengue vaccine (dengue vaccine) recommended; JCI hospital in Cancún |
| Mexico City | Low | None | Altitude 2,240 m. Air quality can be poor. JCI hospital present. |
| Puerto Vallarta / Pacific Coast | Significant (May–Nov) | None (urban) | Dengue vaccine recommended; Jalisco State measles outbreak area |
| Oaxaca | Low–moderate | Some rural municipalities | Discuss malaria prophylaxis if visiting rural areas |
| Chiapas | Moderate | Yes (specific areas) | Malaria chemoprophylaxis recommended for rural travel; TB screening if prolonged stay |
| Los Cabos / Baja | Low | None | Zika risk in Baja California Sur — relevant for pregnant travellers |
Other Health Risks to Know
Zika Virus
Risk exists in scattered areas below 2,300 m, especially in Baja California Sur, Jalisco, Morelos, Sinaloa, and Sonora states. No risk in Mexico City. Pregnant travellers should seek counselling before any trip to Mexico and consider postponing non-essential travel to Zika-risk areas.
Leptospirosis
Risk throughout Mexico, peak August–October. Highest in Sinaloa and Tabasco states. Avoid floodwaters and contaminated freshwater. Wear proper footwear especially after heavy rains. Prophylaxis with weekly doxycycline is an option for high-exposure travellers.
Rocky Mountain Spotted Fever (Rickettsial)
Low risk exists throughout Mexico including popular destinations such as Acapulco, Cancún, Cozumel, Guadalajara, and areas along the Riviera Maya. Transmitted by ticks; peak activity April–September. Observe tick precautions.
Leishmaniasis
Cutaneous risk in Quintana Roo State. Low risk in southern states and coastal areas. Use insect repellent and bed nets especially from dusk to dawn and in shaded areas during the day.
West Nile Virus
Low risk, limited to Nuevo León State. Travellers with significant outdoor exposure in that region should observe insect precautions from dusk to dawn.
Medical Care
Adequate care available in major cities. Mexico City and Cancún have JCI-accredited hospitals. Medical care outside urban centres is generally inadequate. Travel health insurance with emergency evacuation is strongly recommended. Emergency: 911.
