What You'll Learn

Country-specific vaccination requirements
Yellow Fever Vaccine:
Some countries require incoming travellers to be vaccinated against yellow fever, especially if they are arriving from a country designated by the World Health Organization (WHO) as a "country with a risk of yellow fever transmission". This typically needs to be done at least ten days before entering the country, and travellers must present a vaccination record or certificate, such as the International Certificate of Vaccination or Prophylaxis (ICVP or Carte Jaune/Yellow Card). It is important to refer to the official WHO list of countries with a risk of yellow fever transmission to determine if vaccination is required for your specific travel plans.
Polio Vaccine:
While Afghanistan and Pakistan are the only polio-endemic countries as of 2020, several other countries have additional precautionary polio vaccination requirements. These "key at-risk" countries have included China, Indonesia, Mozambique, Myanmar, and Papua New Guinea. Travellers entering or leaving these countries may need to present proof of polio vaccination, typically required within a specific timeframe before their journey.
Meningococcal Meningitis Vaccine:
Certain countries mandate that travellers be vaccinated against meningococcal meningitis before entering or leaving. These countries include The Gambia, Indonesia, Lebanon, Libya, the Philippines, and Saudi Arabia, especially for Muslims visiting Mecca and Medina during the Hajj or Umrah pilgrimages. Proof of vaccination is typically required, and it is preferable to get vaccinated 10-14 days before crossing the border.
COVID-19 Vaccine:
During the COVID-19 pandemic, proof of COVID-19 vaccination became a requirement for international travellers entering certain countries. For example, Australia mandated that unvaccinated international travellers arriving in the country must quarantine at their own expense.
Measles Vaccine:
While measles may be rare in some countries, it is still prevalent in others. The United States, for instance, recommends that children travelling internationally be vaccinated against measles to protect them from contracting the disease and potentially spreading it upon their return.
It is important to note that vaccination requirements can vary across countries and may change over time. Travellers should always refer to the most up-to-date information provided by official sources, such as government health organizations, to ensure they meet the specific vaccination requirements for their destination countries.

Pre-departure vaccination planning
Research and Information:
Before departing, travellers should research the specific health risks and requirements of their destination. The CDC's website provides valuable information on destination-specific vaccines, medicines, and health risks. Checking official government websites and seeking advice from a healthcare provider or travel health specialist is also recommended. This preparation allows travellers to understand the potential health hazards and take the necessary preventive measures.
Timing and Planning:
It is advisable to schedule a pre-travel health consultation with a healthcare provider or travel clinic 4-6 weeks before departure. This timing ensures that travellers have sufficient time to receive any necessary vaccines or medications. During the consultation, travellers should discuss their health concerns, itinerary, and planned activities to receive tailored advice and recommendations.
Vaccination Requirements and Recommendations:
Certain destinations may require specific vaccinations, such as the yellow fever vaccine for travel to certain regions. It is important to review routine immunizations and determine if any additional travel immunizations are advised based on the traveller's medical history and destination. Malaria chemoprophylaxis, for example, may be recommended for itineraries where malaria transmission is a risk.
Health Considerations:
Travellers with underlying health conditions, such as cardiac disease or asthma, should pay extra attention to health issues related to their destination and activities. Carrying medical reports, recent electrocardiograms, and necessary medications is essential. Immunocompromised individuals should consult specialists before departure, as they may need to avoid certain vaccines or take additional precautions.
Documentation and Testing:
Travellers should obtain and carry documentation of their administered immunizations, such as the International Certificate of Vaccination or Prophylaxis (Yellow Card). Additionally, some countries may require proof of a negative COVID-19 test or recovery from COVID-19 for entry, so travellers should stay informed about the latest requirements.
By following these pre-departure vaccination planning steps, travellers can proactively manage their health and well-being, ensuring a more enjoyable and safe journey.

In-country health precautions
When preparing for international travel, it is important to take certain health precautions to ensure your safety and well-being. Here are some in-country precautions to consider before leaving to travel abroad:
Health Precautions:
- Review Travel Advisories and Country Information: Check the official U.S. government travel advisories and specific country information for your destination. This includes information on safety, entry and exit requirements, local laws, health guidelines, and other important details. Sign up for STEP to receive timely alerts and updates from the nearest U.S. embassy while abroad.
- Visit a Healthcare Provider: Make an appointment with your healthcare provider or a travel health specialist at least 4-6 weeks before your departure. Discuss your health concerns, itinerary, and planned activities to receive destination-specific advice and recommendations. Ensure you bring a copy of your official immunization records with you when you travel.
- Medications and Prescriptions: Take recommended medications as directed by your doctor. Bring enough prescription and over-the-counter medications to last your entire trip, plus extra in case of delays. Some prescriptions and over-the-counter medications may be illegal in certain countries, so check the health section of your destination's travel guidance. Always bring copies of your prescriptions and labeled bottles.
- Travel Health Kit: Prepare a travel health kit with essential items, especially those that may be difficult to find at your destination. Include items such as masks, insect repellent, sunscreen, hand sanitizer, and your health insurance card.
- Travel Insurance: Find out if your health insurance covers medical care abroad. Consider purchasing additional insurance that covers healthcare and emergency evacuation, especially if traveling to remote areas.
- Embassy and Emergency Contacts: Inform your family members that they can contact the local embassy or consulate for help if they have concerns about your safety. Ensure you have the necessary contact information for the U.S. embassy or consulate at your destination.

Re-entry requirements
The re-entry requirements for travellers returning from international destinations vary depending on the country of origin and the traveller's vaccination status. It is important to check the specific requirements for your country of origin before planning your travel. Here are some general guidelines and considerations for re-entry requirements:
- Vaccination Documentation: Many countries require proof of vaccination for entry. For example, the United States mandates that non-citizens be fully vaccinated before entering the country. It is recommended to carry physical or digital copies of your vaccination records, as you may be asked to present them upon re-entry.
- COVID-19 Testing: In addition to vaccination requirements, some countries may also request a negative COVID-19 test result within a specified timeframe before your return. Check with your local health authorities or travel advisories for the latest testing requirements and guidelines.
- Destination-Specific Considerations: The re-entry requirements may differ based on the countries you have visited. For example, if you are returning from a region with a high risk of certain diseases, you may need to provide proof of specific vaccinations. This is particularly true for areas with yellow fever, as some countries will require a yellow fever vaccination certificate for both entry and re-entry.
- Transit and Layover Locations: When planning your travel, consider not only your destination but also any transit or layover locations. Some countries may have specific requirements for travellers passing through their airports or transportation hubs, including proof of vaccination or negative COVID-19 test results.
- Timing and Quarantine Rules: Keep yourself updated on the timing and quarantine rules for your country of origin. Some countries may require returning travellers to undergo a mandatory quarantine period, especially if you are unable to provide the necessary vaccination documentation or negative test results.
- Medical Exemptions: If you have a medical condition that prevents you from receiving certain vaccines, make sure to consult your healthcare provider and seek official documentation. Some countries may allow exemptions for specific vaccines, but you will still need to follow their guidelines for unvaccinated individuals, which may include testing and quarantine protocols.
It is always advisable to stay informed about the latest travel advisories and recommendations from official sources, such as government health organizations or foreign affairs departments, to ensure a smooth re-entry process when returning from international travel.

Post-travel health checks
While there is no universal requirement to be vaccinated to leave the country, it is important to check the specific entry requirements of your destination country, as these may include vaccination mandates. For instance, as of May 2022, vaccinated travellers could leave the US without restrictions, but they needed a negative COVID-19 test to return.
During your trip, it is important to follow basic health and safety practices, including frequent handwashing, wearing a seatbelt, using a helmet when riding a motorcycle or bicycle, practising safe sex, and taking measures to prevent communicable diseases. It is also recommended that you check in regularly with someone back home and provide them with your contact information and itinerary.
After your trip, it is important to continue practising self-care and monitoring your health. If you experience any symptoms of illness, such as fever, cough, or difficulty breathing, it is recommended that you seek medical attention and share your travel history with your healthcare provider. Additionally, if you have been exposed to any infectious diseases during your trip, it is important to get tested and, if necessary, receive treatment.
For travellers who have recovered from a documented COVID-19 infection within the last three months, it is recommended to follow the requirements and recommendations for fully vaccinated travellers. Testing is not required 3-5 days after travel unless symptomatic. However, it is important to be aware that individuals can continue to test positive for up to three months after diagnosis without being infectious to others.
