The Edge · Health & Travel
The Edge has no Yellow Fever requirement, but polio needs active management, especially for Papua New Guinea, and malaria prophylaxis is essential in several countries. Always talk to your doctor or a travel clinic for personalized guidance.
Heads up
Get the adult polio booster before departure. If any stay in PNG exceeds 4 weeks, document a polio dose on an ICVP card for exit and onward travel.
No country on The Edge requires Yellow Fever for U.S. travelers on this itinerary. Polio is the real one to manage, Papua New Guinea is on CDC's circulating-poliovirus list, and long stays can trigger an exit-vaccination rule.
| Vaccine | Notes | Source |
|---|---|---|
| Yellow Fever, not required | No country on this itinerary is a Yellow Fever risk country, so the "arriving from a risk country" trigger never fires at any border. South Africa, Eswatini, and Mozambique only ask for the certificate from people arriving from risk zones, which you won't be. Skip it. | CDC: Yellow Fever Map |
| Polio, the one to manage | PNG is on CDC's current circulating-poliovirus list. Under WHO's temporary recommendations, long-term visitors who stay more than 4 weeks in a polio-affected country should receive a polio dose, with proof, 4 weeks to 12 months before departing. Some onward countries also require proof from travelers arriving from polio-affected countries (Indonesia, PNG, Philippines), inconsistently enforced. Practical call: everyone gets the adult polio booster before departure; if PNG stays exceed 4 weeks, document it on an ICVP card. | GPEI: Travel Advice |
| Vaccine | Notes | Source |
|---|---|---|
| MMR (measles, mumps, rubella) | Measles is circulating in the region. | , |
| Tdap (tetanus, diphtheria, pertussis) | Standard adult booster. | , |
| Polio booster | Adult booster recommended for this route regardless. | , |
| Varicella (chickenpox) | If not previously immune. | , |
| Influenza (seasonal) | Annual flu shot. | , |

| Vaccine | Notes | Source |
|---|---|---|
| Hepatitis A | Essential for the entire route, food and water exposure throughout. | CDC: Hepatitis A |
| Typhoid | Recommended across the developing-country legs, rural South Africa, Mozambique, Indonesia, Philippines, Sri Lanka, Thailand, PNG. | CDC: Typhoid |
| Hepatitis B | Recommended given close-contact ministry and length of stay. | Immunize.org |
| Japanese Encephalitis | Key for the Asia-Pacific leg, JE occurs throughout much of Asia and the Western Pacific including eastern Indonesia and PNG. Recommended for travelers spending a month or more in endemic areas during transmission season; shorter rural stays worth considering. Also present in the Philippines, Malaysia, Thailand, Sri Lanka, and Japan. | CDC: Japanese Encephalitis |
| Rabies (pre-exposure) | High priority for PNG, Indonesia (Bali dog rabies), the Philippines (very high burden), Sri Lanka, and Thailand. Japan and Australia are rabies-free. | CDC: Rabies |
| Cholera | Consider for Mozambique (recurrent outbreaks) and parts of SE Asia/PNG with poor sanitation. | CDC: Cholera |
Heavily site-dependent. Two countries on this route are serious: Papua New Guinea (among the highest malaria risk in the world) and Mozambique (high risk throughout). Each participant needs an individual clinic consult to choose a regimen.
| Vaccine | Notes | Source |
|---|---|---|
| Papua New Guinea | Among the highest malaria risk in the world. Prophylaxis essential. | CDC: Malaria Map |
| Mozambique | High risk throughout. Prophylaxis essential. | , |
| South Africa | Only the low-altitude northeast (Kruger, Limpopo, Mpumalanga, far-northern KwaZulu-Natal). None in Cape Town or Johannesburg. | , |
| Eswatini | Eastern lowveld only. | , |
| Indonesia | High in Papua/eastern islands; low to none in Bali, Java, and Jakarta. | , |
| Philippines / Malaysia / Thailand | Rural and border/interior areas only (Palawan & Mindanao; Borneo interior; Thai border provinces), not the main cities. | , |
| Sri Lanka | Malaria-free (WHO-certified since 2016). No prophylaxis needed. | , |
| Australia & Japan | No malaria. | , |
Dengue is widespread across the tropical stretch of this route, no standard travel vaccine for first-time-exposure travelers, so use mosquito precautions (repellent, covering up) rather than a shot.
