Visiting immunization clinic before traveling is important to get vaccines that reduce the risk of exposure to diseases and to get any necessary prescription, notes Cleveland Clinic. Immunization clinics also offer pretravel consultation services and official vaccine certificate documentation.
Visit an immunization clinic at least 4 to 6 weeks before traveling to give time for the vaccine to take effect, according to the Centers for Disease Control and Prevention. This ensures there is enough time to complete vaccines that require more than one dose. Travelers with a pre-existing health condition need to visit a physician specializing in travel medicine. Some countries require written documentation of vaccines administered from all travelers.
