3. Yellow Fever
Yellow fever is a viral infection transmitted by mosquitoes. It is found in tropical regions of Africa and South America. The yellow fever vaccine is a single dose that provides lifelong protection for most people. Some countries require proof of vaccination for entry, so be sure to check the requirements before you travel.
4. Hepatitis B
Hepatitis B is a viral infection that affects the liver and can be transmitted through blood, bodily fluids, or contaminated needles. The Hepatitis B vaccine is given in three doses over six months. It provides long-term protection against the disease.
5. Japanese Encephalitis

The Japanese encephalitis vaccine is given in two doses, 28 days apart. It is recommended for travelers to endemic areas who plan to spend time outdoors or in rural settings.
6. Rabies
Rabies is a viral infection that affects the nervous system and is almost always fatal once symptoms appear. It is transmitted through the bite or scratch of an infected animal. The rabies vaccine is given in three doses over 21-28 days. It is recommended for travelers to high-risk areas, particularly those who will be in close contact with animals.
7. Polio
Polio is a viral infection that can cause paralysis and death. It has been eradicated from most of the world, but it still exists in some countries like Afghanistan and Pakistan. The polio vaccine is given as a part of routine childhood vaccinations, but adult travelers to high-risk areas should receive a one-time booster dose.
8. Influenza
Influenza, or the flu, is a viral infection that affects the respiratory system. It is prevalent worldwide and can cause severe complications, especially in young children, the elderly, and people with underlying health conditions. The influenza vaccine is updated annually to protect against the most common strains of the virus. It is recommended for all travelers, particularly during flu season.
9. Measles, Mumps, and Rubella (MMR)
Measles, mumps, and rubella are viral infections that can cause serious health problems. The MMR vaccine is given in two doses during childhood. Adult travelers who have not been previously vaccinated or do not have immunity should receive two doses of the vaccine, 28 days apart.
10. Tetanus, Diphtheria, and Pertussis (Tdap)
Tetanus, diphtheria, and pertussis are bacterial infections that can cause severe complications. The Tdap vaccine is given as a part of routine childhood vaccinations, with a booster dose every 10 years for adults. Travelers should ensure they are up-to-date with their Tdap vaccination before embarking on international travel.
Potential Side Effects of Vaccinations
Most vaccines have mild side effects, such as soreness at the injection site, mild fever, or fatigue. However, serious side effects are rare. It is important to discuss any concerns with your healthcare provider before receiving any vaccinations.
Consulting with a Travel Medicine Specialist
Before your trip, it is important to consult with a travel medicine specialist who can provide personalized recommendations based on your destination, duration of travel, and health history. They can also inform you of any additional vaccinations or precautions that may be necessary for your specific itinerary.
