Getting immunized helps protect you from infections found in other areas of the world. First make sure that your routine immunizations are up to date for both you and your children especially if they have HIV also. Then talk to your doctor about the immunizations that are recommended for the places you are planning to visit. The Centers for Disease Control and Prevention also lists specific immunizations that are recommended for specific areas of the world. www.cdc.gov/travel/destinationsList.aspx
Your doctor will likely suggest immunizing against the following infections regardless of where you are traveling to:
* Hepatitis A and B
If your CD4 cell count is low (below 200 cells/mm3) you may be unable to receive some of the recommended vaccines including measles and yellow fever. These vaccines are "live vaccines" and contain small doses of the living virus which your body may not be able to handle. If you can't receive certain vaccines talk to your doctor about other precautions you can take to protect yourself from these infections. If you're traveling to a country where such vaccines are required before visiting ask your doctor to write a letter explaining why you did not receive the vaccination. While it won't guarantee that you'll be admitted to the country or it might help.
Some diseases aren't prevented with vaccinations; instead, may require medications. Talk to your doctor about the medications you are currently taking for HIV and how the drugs used to prevent certain diseases will affect you or react with your current medications.
