Traveling to other countries often requires additional vaccinations. While you must have proof that your vaccines are up to date (MMR, Tetanus, Diphtheria, etc.), you may need to be vaccinated against rare diseases. It depends on the country you will be visiting.
If you are going to Mexico, Central America, Trinidad and Tobago, or South America, the vaccine for Yellow Fever is required in most rural areas. Vaccinations for Hepatitis A and B, Rabies, and Typhoid are recommended. It is also urged that you see your health care provider for a prescription for anti-malarial drugs before you leave.
Travelers to Western and Eastern Europe do not need additional vaccinations. However, it is recommended that you receive the vaccine for Hepatitis A and B. If you are going to a warmer area (Spain, Greece) where mosquitoes may be present, you will want a prescription for anti-malarial medication.
When traveling to Africa, it is essential that you receive the vaccination for Yellow Fever. Other vaccinations are suggested, but not required. They include the vaccinations for Hepatitis A and B, Meningococcal, Rabies, Typhoid, and polio.
For gaining entry into the Middle East, proof of polio and meningococcal vaccinations are required. Though not required, Hepatitis A and B, Rabies, and Typhoid vaccines are highly recommended. It is also important to receive anti-malarial pills from your doctor.
Travel to Asia requires no vaccines, but many vaccinations are urged. Hepatitis A and B, Japanese encephalitis, Rabies, and Typhoid are among the vaccines currently suggested by health agencies. If you are traveling to an area where mosquitoes are present, anti-malarial pills are also recommended.
Finally, Australia and the South Pacific suggest vaccinations for Japanese encephalitis, Hepatitis A and B, Rabies, and Typhoid. There are no required vaccines though.
While many of these vaccines are not mandatory, you should discuss your travel plans with your doctor. He or she will have up to date information on the current outbreaks in the area to which you are traveling.
