In Green/Shutterstock Now that travel is an option again for many, eager wanderers are facing difficult decisions about where to go. After all, no one's really been able to go anywhere for more than a year. If you're American and have had your eye on Malta, however, you're going to have to keep waiting. The island nation is the first European Union member state to require proof of vaccination from visitors, according to the Associated Press. Starting July 14, visitors ages 13 and up will have to show proof of full vaccination to be granted entry. Travelers between the ages of five and 12 joined by vaccinated adults will have to show proof of a negative PCR test, while children under five don't need to show anything.
