Vaccine Preventable Diseases & Immunizations

Find out more about the diseases you may encounter, and the vaccine information that can help protect you.

Yellow Fever


  • Yellow fever is a viral illness, transmitted by some species of mosquitoes in Central and South America, and in tropical regions of Africa
  • A mild attack may have symptoms similar to those of the flu
  • More severe symptoms may include nausea, vomiting, bleeding, abdominal pains, and yellowing of the skin as a result of liver damage1


  • Avoid mosquito bites
  • Vaccination may also be considered. Documentation of vaccination is required in some countries.1

Travelers can reduce their risk of acquiring yellow fever by:

  • Remaining in well-screened or air-conditioned areas when possible
  • Wearing clothing that adequately covers the arms and legs
  • Applying DEET-containing insect repellent to both skin and clothing

Yellow fever vaccination may be required for entry if you are traveling to, or transiting through, a country where the disease exists.1

Consult your travel physician for additional health information.

For more information visit:


  • Immunization is required in certain countries1
  • Vaccine must be administered at a state authorized yellow fever vaccination center or provider1 (contact your local state health department for the nearest vaccination center)
  • If vaccination is appropriate, your health care provider will administer a single dose of vaccine and provide you with a completed International Certificate of Vaccination
  • This certificate is valid 10 days after vaccination and for a subsequent period of 10 years
  • This certificate should be carried with your passport at all times1


Vaccines can help protect you from diseases that are still common in many parts of the world. Make certain you contact your health care provider and determine which vaccines you should receive before you travel.

Diseases to Guard Against

When you’ve added your destinations, it is recommended that you take this list to your doctor so you can discuss relevant vaccinations before you travel.

Travel vaccines help protect you from illnesses present in other parts of the world, and help prevent the importation of infectious diseases across international borders. Which vaccinations you need depends on a number of factors, including your age, health status, and previous immunizations.


There are combination vaccines that help protect against multiple diseases that may reduce the number of shots you need.
