Travel Vaccines 2023

Getting vaccinated against infectious diseases is one of the most effective ways to protect your health while traveling abroad, says the World Health Organization (WHO). According to the U.S. Centers for Disease Control and Prevention (CDC) and the U.K.'s Foreign Travel Advice, most travel vaccines should be administered at least one month before departure to ensure maximum protection. Various U.S. Food and Drug (FDA) and European Medicines Agency (EMA) travel vaccines are approved, and the WHO's Listed as of September 2023. During 2023, innovative clinical trials empower people to participate in vaccine development and potentially receive compensation.

The CDC's Travel Assessment enables travelers to confirm vaccine requirements for each country. In addition, the CDC published an update to Frequently Asked Travel Questions and Answers. The Pan American Health Organization (PAHO) published updated travel vaccine recommendations in 2023. The WHO and European Commission announced in June 2023 that the European Union digital certification system will become a global system facilitating international mobility.
