No specific vaccinations are required for our European destinations, but we recommend consulting with a healthcare professional or checking the Centers for Disease Control and Prevention (CDC) website for the most up-to-date recommendations for the countries you will be visiting. However, individual countries may have their own entry requirements, including proof of a negative COVID-19 test or quarantine regulations upon arrival. It's always best to check with your destinations' government websites for the most up-to-date information and to comply with any rules and regulations.
