Most travelers to Peru need four to six vaccines beyond their routine immunizations: hepatitis A, typhoid, yellow fever (depending on your itinerary), hepatitis B, and potentially rabies. Peru does not require proof of any vaccine for entry, but the CDC recommends several based on the diseases you can encounter there. Ideally, schedule a travel health appointment at least four to six weeks before your trip so every vaccine has time to build protection.
Vaccines Recommended for Nearly All Travelers
Hepatitis A tops the list. The virus spreads through contaminated food and water, and even upscale restaurants in Lima can’t guarantee zero risk. A single dose before departure provides strong protection, and a booster six to twelve months later gives immunity that lasts decades. If your trip is less than two weeks away and you haven’t been vaccinated, a dose at any point before travel still offers meaningful coverage.
Typhoid is recommended for most travelers, especially if you’re staying with friends or relatives, visiting smaller cities, or spending time in rural areas. The vaccine comes in two forms: an injectable shot (one dose, protection in about two weeks) or an oral series of four capsules taken every other day over a week. Neither version is 100% effective, so safe food and water habits still matter, but the vaccine significantly cuts your risk.
Make sure your routine immunizations are current before you go. That means measles-mumps-rubella (MMR), diphtheria-tetanus-pertussis (Tdap or a tetanus booster if it’s been more than ten years), polio, and your annual flu shot. COVID-19 vaccination is no longer required for entry into Peru.
Yellow Fever: Depends on Where You’re Going
Yellow fever vaccination is recommended if your itinerary includes the Amazon basin or other jungle regions in eastern Peru, including popular destinations like Iquitos, Puerto Maldonado, and Manu National Park. The virus is transmitted by mosquitoes in tropical lowland areas, and the disease can be severe. If you’re only visiting Lima, Cusco, Machu Picchu, and the highlands, yellow fever vaccination is generally not necessary because the mosquitoes that carry the virus don’t thrive at high altitudes.
Peru does not require a yellow fever certificate for entry. However, if you plan to travel onward to countries like Brazil, Bolivia, or several African nations, those countries may demand proof of vaccination. The yellow fever vaccine is a single dose that provides lifelong immunity, but it needs to be given at least ten days before you enter a risk area for the certificate to be considered valid. Some travelers with certain immune conditions or egg allergies cannot receive this vaccine, so discuss alternatives with a travel health provider.
Hepatitis B and Rabies: Based on Your Activities
Hepatitis B spreads through blood and bodily fluids. It’s recommended if there’s any chance of medical procedures, tattoos, or sexual contact during your trip. The standard series is three doses over six months, but an accelerated schedule can compress that timeline for last-minute travelers. Many adults vaccinated as children are already covered, so check your records before booking an extra appointment.
Rabies pre-exposure vaccination is worth considering if you plan to spend time in rural areas hiking or cycling, if you’ll be around animals (especially dogs or bats), or if you’re traveling with young children who are more likely to approach stray animals. The CDC specifically flags expatriates, veterinarians, researchers who may contact bats, and remote trekkers as candidates for the rabies series. The pre-exposure course is two doses given a week apart. It doesn’t eliminate the need for treatment after a bite, but it simplifies and shortens the post-exposure protocol dramatically, which matters when you’re far from a major hospital.
Malaria and Mosquito-Borne Diseases
There’s no widely available vaccine for malaria, so prevention relies on antimalarial medication and mosquito avoidance. Malaria risk in Peru is concentrated in the Amazon lowlands. If you’re heading to jungle lodges around Puerto Maldonado or Iquitos, talk to your provider about a prescription antimalarial. The highland circuit (Cusco, Sacred Valley, Machu Picchu) and coastal cities like Lima carry little to no malaria risk.
Dengue, Zika, and chikungunya are also present in Peru’s tropical lowland and coastal regions, all transmitted by daytime-biting mosquitoes. No vaccine for these is part of standard travel preparation. Your best defense is insect repellent containing at least 20% DEET or picaridin, long sleeves and pants during peak biting hours, and permethrin-treated clothing. Pregnant travelers or those planning pregnancy should discuss Zika risk specifically with their provider before visiting affected areas.
Timing Your Vaccines
Four to six weeks before departure is the sweet spot for a travel health visit. That window gives enough time for multi-dose series to build protection and for single-dose vaccines like yellow fever to reach full effectiveness. Some vaccines, like the oral typhoid capsules, need to be completed at least one week before travel. Hepatitis A and the injectable typhoid shot both work quickly enough to help even if you’re only two weeks out.
If your trip is days away and you haven’t started, go anyway. Partial protection is better than none, and your provider can prioritize the highest-risk vaccines for your specific itinerary. Bring a list of where you’re going and what you’ll be doing: a week at a Lima hotel is a very different risk profile from a trek through the Amazon followed by homestays in the Andes.
Altitude Sickness Is Not a Vaccine, but Plan for It
Cusco sits at 3,400 meters (about 11,150 feet), and many travelers feel the effects within hours of landing. Altitude sickness isn’t something you can vaccinate against, but it’s one of the most common health issues for Peru visitors and worth addressing at the same travel health appointment where you get your shots.
A prescription medication called acetazolamide (Diamox) is the most reliable preventive option. The typical dose for prevention is 125 mg every 12 hours, starting the day before you ascend and continuing for at least two days at altitude. It works by speeding up your body’s natural adjustment to lower oxygen levels. Side effects include tingling in the fingers, increased urination, and a flat taste to carbonated drinks, all harmless.
The simplest non-medication strategy is arriving gradually. If your schedule allows, spend a night or two at a lower elevation first. The Sacred Valley (about 2,800 meters) sits lower than Cusco and makes a good first stop. Once above 3,000 meters, best-practice guidelines recommend limiting your nightly sleeping elevation gain to 500 meters and adding an extra rest night for every 1,000 meters gained. Coca tea is a traditional Andean remedy sold everywhere in the highlands, but high-quality evidence for its effectiveness is limited. Treat it as a pleasant supplement, not a replacement for gradual ascent or medication.
Serious complications like fluid in the lungs (breathlessness at rest, persistent cough) or brain swelling (confusion, loss of coordination) are rare but require immediate descent. Canned oxygen shots and oxygen bars are widely marketed to tourists but lack evidence and shouldn’t be relied on.
