In general you don’t need vaccinations for Curaçao, unless you’ve traveled to a country with a risk of yellow fever 6 months before you arrive on our island. In that case you would need to have proof of vaccination with you, or an official document of exemption before you are permitted entry into Curaçao. You can find a current list of countries with a risk of yellow fever here: www.cdc.gov/yellowfever/maps/
