Brazil is a destination that needs real preparation. While there are no required vaccines, the recommended vaccines include Hepatitis A, Hepatitis B, and Rabies. Additionally, malaria is a regional concern in the Amazon, and dengue is prevalent throughout the country. This trip requires careful planning and attention to health prep.
Travelers should focus on getting vaccinated against Hepatitis A and Rabies, especially if visiting rural areas. Those planning to explore the Amazon should consider malaria prophylaxis. This preparation is essential for a safe and enjoyable trip.
Why timing matters
Start at least 8 weeks before departure. Schedule vaccinations for multi-dose vaccines like Hepatitis B and Rabies, and ensure malaria prophylaxis is filled and started if traveling to high-risk areas. Do not leave it to the last week to get your shots.
Key takeaways
- Hepatitis A is often overlooked; get vaccinated 4 weeks before travel.
- Plan for malaria prevention if visiting the Amazon region; start 1-2 weeks prior.
- Rabies vaccination is crucial for those engaging in outdoor activities or animal contact.
- Dengue is prevalent; pack mosquito repellent with at least 30% DEET.
- Routine vaccines are not listed here; ensure MMR and DTaP are up to date.
Vaccinations Overview
The table below outlines the required and recommended vaccines for Brazil.
| Category | Vaccine | Who | Why | When to start | Cost | Side effects | Notes |

What border officers actually check
No vaccinations are required to enter Brazil for typical short tourist stays. This typically means visits of up to 90 days. However, a Yellow Fever certificate is required if you arrive from or transit through a Yellow Fever risk country for more than 12 hours. Countries like Colombia and Peru fall into this category, so be aware of your travel route.
If you transit through a Yellow Fever risk country for 12 hours or more, you must present a Yellow Fever vaccination certificate upon arrival in Brazil. Common transit hubs that travelers might overlook include Doha and Addis Ababa. Remember that ‘transit’ means staying airside; if you go through immigration, you will need the certificate. Flight delays can extend a layover, so check your itinerary carefully.
Documentation is checked upon arrival, with officers verifying the International Certificate of Vaccination or Prophylaxis (ICVP). They will look for the issuance date, ensure it is signed by an approved center, and confirm that your name matches your passport. Entry rules can change, so confirm with the embassy or your travel clinic at least four weeks before departure. Digital alternatives may be accepted, but if your card is lost during your trip, consult local health authorities immediately.
Health risks without a vaccine
Even with vaccinations, travelers face various health risks in Brazil. Mosquito-borne diseases are prevalent, and malaria is a concern in specific regions like the Amazon. The following table outlines the key diseases you might encounter, along with prevention strategies.
| Risk | Presence | High-risk situations | Prevention | When to see a doctor |
|---|---|---|---|---|
| Dengue | Year-round, peaks during wet season (November to March) | Dusk-to-dawn outdoors, urban gardens with standing water | Use DEET 30% or higher, wear long sleeves and pants | Fever 38 degrees C+ within 14 days of return |
| Malaria | Regional, mostly in the Amazon and parts of Maranhão, Mato Grosso, Pará | Traveling in forested areas, especially at night | Consult a travel clinic about prophylaxis options | Fever 38 degrees C+ within 14 days of return |
| Rabies | Country-wide, urban and rural, especially in wildlife areas | Contact with stray dogs or bats | Avoid animal bites and seek immediate care if bitten | Any animal bite or scratch – wash and clinic within 24h |
| Chikungunya | Year-round, peaks during wet season (November to March) | Outdoor activities in urban areas with standing water | Use DEET 30% or higher, wear long sleeves and pants | Severe joint pain lasting more than a week |
| Leptospirosis | Wet-season risk (November to March) | Swimming or wading in floodwaters | Avoid contact with potentially contaminated water | Fever, muscle aches, or jaundice after exposure |
Your prep timeline
Start at least eight weeks before departure – Brazil sits in the heavy-preparation bracket. Begin by booking a travel-clinic consult to discuss your vaccination needs. Recommended vaccinations like Hepatitis B require a multi-week schedule, so starting early is crucial. Malaria prophylaxis should be filled four weeks before departure to ensure effectiveness. Leaving prep to the last week can lead to missed vaccinations and unnecessary health risks.
| Activity | Ideal timing | Deadline | Why |
|---|---|---|---|
| Book travel-clinic consult | 10-12 weeks before departure | Latest: 4 weeks before departure | Consult early to assess vaccination and health needs. |
| Start recommended vaccinations | 8-10 weeks before departure | 2 weeks before departure (single-dose shots only) | Hepatitis B uses an accelerated 4-week schedule. |
| Fill malaria prophylaxis prescription | 4 weeks before departure | Start atovaquone-proguanil 1-2 days before entry; doxycycline 1-2 days before; mefloquine 2-3 weeks before | Malaria prophylaxis must be in your system before exposure. |
| Get Yellow Fever certificate | 10+ days before entry | Certificate must be issued at least 10 days before crossing the border | Yellow Fever vaccination is strongly recommended for most regions. |
| Pick up final medicine kit + insurance paperwork | 1-2 weeks before departure | Day before departure at the latest | Ensure you have all necessary medications and documents. |
Documents to carry
Carry the International Certificate of Vaccination or Prophylaxis (ICVP), also known as the Yellow Card, especially if you receive the Yellow Fever vaccine. Digital alternatives may be available through health apps, but always bring physical copies. When visiting the travel clinic, bring your current vaccination record, a list of medications, your trip itinerary including any rural or jungle days, and any known allergies. Keep the ICVP with your passport while storing other documents in a separate, secure bag.
What this prep costs
Expect to spend USD500-1100 for a basic package. This typically includes the travel-clinic consult fee, vaccination costs, and the ICVP fee. Malaria prophylaxis prescriptions can add another USD80-200 for the trip duration. National or private insurance usually covers routine boosters but may vary for travel-specific vaccinations and ICVP fees. A good travel insurance covers post-vaccination side effects, medical evacuation, and unexpected illness abroad; pre-existing conditions and routine vaccinations are typically excluded. Always ask the clinic for a written cost estimate before starting a multi-dose schedule.

Mosquito prevention
Mosquitoes carry both dengue and malaria here – protect both during the day (dengue Aedes) and at dusk/night (malaria Anopheles).
- • Apply DEET 20-30% on exposed skin for adults and 10% for children over 2 months.
- • Wear permethrin-treated clothing during evenings to deter mosquitoes.
- • Sleep in screened or air-conditioned rooms to reduce mosquito exposure.
- • Avoid standing water to minimize mosquito breeding sites.
- • Adjust activities to avoid being outside during dusk and dawn when malaria mosquitoes are active.
- • Reapply insect repellent every 4-6 hours for continuous protection.
Food and water hygiene
Traveler’s diarrhea is the most likely thing to ruin a trip in Brazil – more common than every vaccinated-against disease combined.
- • Drink bottled or filtered water with a 0.1 micron filter to avoid waterborne diseases.
- • Avoid ice cubes in rural areas; stick to ice from reputable sources in urban settings.
- • Choose peeled fruit over unpeeled to minimize contamination risk.
- • Eat from busy street food stalls that serve hot, fresh food to reduce foodborne illness risk.
- • Carry oral rehydration salts (ORS) to manage dehydration from diarrhea.
- • Use hand sanitizer with at least 60% alcohol to maintain hygiene before meals.
