Immunizations are important when you are traveling internatlionally

It can be overwhelming to navigate your to-dos before an international trip. Don’t let health preparations fall off of your list.

To minimize your risk of becoming seriously ill during international travel, it is important to find out which immunizations may be required or recommended for visiting different regions of the world.

Peter Veldkamp, MD, director of Travel Health at the UPMC Center for Care of Infectious Diseases, recommends scheduling a medical consultation with your physician four to six weeks before an international trip. Your physician can help you determine which vaccines may be necessary based on your travel itinerary, including the need for malaria prophylaxis, and can provide guidance on food and water safety tips, including information on the best agents to manage and/or treat traveler’s diarrhea.
