Planning travel to Peru? The yellow fever answer depends on two separate questions: whether vaccination is recommended for the places on your itinerary, and whether you need proof of vaccination to enter. Those are not always the same.
The short answer: Peru does not require yellow fever vaccination for entry. CDC recommends it for many lower-elevation areas, but not for a Cusco, Inca Trail, or Machu Picchu-only itinerary.
Last reviewed by Runway Health: September 22, 2026. This guidance was checked against the current CDC traveler guidance for Peru and the WHO country list. Border rules and health notices can change, so confirm the current requirement with the relevant embassy, consulate, or airline before departure.
Yellow fever recommendation vs. entry rule for Peru
Recommendation: CDC recommends vaccination for travelers aged 9 months and older going to specified areas below 2,300 m (7,550 ft), including areas in Amazonas, Cusco, Huánuco, Junín, Loreto, Madre de Dios, Pasco, Puno, San Martín, and Ucayali. It does not recommend it for Lima, highland tourist areas such as Cusco, the Inca Trail, and Machu Picchu, or most higher-elevation and west-of-Andes travel.
Entry requirement: CDC lists no yellow fever certificate requirement for entry to Peru. The recommendation still depends on your specific regions, especially if your itinerary includes the Amazon or eastern lowlands.
Your full route matters. A long transit or travel before your final destination can affect documentation rules. For a first vaccination, the International Certificate of Vaccination or Prophylaxis (ICVP, or yellow card) becomes valid 10 days after vaccination. Keep it with your passport if your route requires proof.
How to decide whether you need the vaccine
- Map every stop. Include countries visited before Peru, airport transits, regions, and approximate layover lengths.
- Match your itinerary to CDC’s regional guidance. A city trip can have a different recommendation from a rural, forest, border, or safari itinerary.
- Plan early. Build in time for a clinician to assess whether vaccination is appropriate and for a first ICVP to become valid.
- Use an authorized yellow fever center when documentation matters. The vaccination site must be able to issue and validate the ICVP.
Yellow fever vaccine is not appropriate for every traveler. Age, pregnancy, immune-system conditions, certain allergies, and prior vaccine history can affect the decision. If it is medically contraindicated, an authorized provider may be able to issue a waiver, but acceptance is decided at the border. Do not rely on a waiver without confirming the current policy.
Do you need malaria medication for Peru?
CDC recommends prescription malaria prevention for areas below 2,500 m (8,200 ft) east of the Andes, including Iquitos and Puerto Maldonado, with rare cases in Tumbes and Piura. It lists no transmission in Lima, Cusco, Machu Picchu, Lake Titicaca, and several other common highland and southern-coast destinations. In the main prevention areas, CDC lists atovaquone-proguanil, doxycycline, mefloquine, and tafenoquine.
Yellow fever vaccination and malaria prevention solve different problems. Even where no malaria medicine is indicated, mosquito-bite prevention remains important. Use EPA-registered repellent, wear protective clothing when practical, and choose screened or air-conditioned lodging where available.

Other travel-health planning to consider
- Altitude illness: Cusco and Machu Picchu trips can involve rapid ascent; medication and acclimatization planning deserve a separate conversation.
- Traveler’s diarrhea: A treatment plan may be useful for remote or high-activity itineraries.
- Typhoid: Discuss vaccination for rural travel, longer stays, or visits with friends and relatives.
- Routine vaccines: Check that routine immunizations, including MMR, are current.

Can Runway Health help?
A Runway physician can review your itinerary and health history, discuss whether yellow fever vaccination is appropriate, and, if appropriate, prescribe yellow fever vaccine for local administration. Travelers who need an ICVP should confirm that their vaccination site is an authorized yellow fever center that can issue and validate the certificate.
Runway can also help eligible travelers evaluate prescription options for malaria prevention, traveler’s diarrhea, nausea, motion sickness, and other travel needs. A consultation does not replace checking current destination requirements for your exact route.

Frequently asked questions
Do I need a yellow fever vaccine if I am only transiting?
Possibly. Some destinations set certificate rules based on prior travel or a transit through a yellow-fever-risk country, sometimes only after a qualifying layover. Review the entry rule for your final destination and every stop on your itinerary.
Can a Runway physician give me a yellow fever vaccine?
A Runway physician may prescribe yellow fever vaccine for local administration when appropriate. If you need the ICVP for entry, use an authorized yellow fever vaccination center that can complete and validate that document.
When should I seek care after travel?
Seek urgent medical care for fever during or after travel to a malaria-risk area, and tell the clinician about your travel. Do not wait to see if a fever resolves on its own.
The bottom line
Peru planning starts with a direct yellow fever answer, but a safe itinerary also considers your route, local disease risk, and other medications that may fit your plans. For the broader framework—including certificate timing and transit rules—see our yellow fever vaccine travel guide.
