With coronavirus vaccines becoming more widely available and the Centers for Disease Control and Prevention (CDC) recently clearing fully vaccinated people for travel, many of us are eager to start planning our first post-pandemic trips. Countries are once again welcoming international visitors, tooâsome, with unique rules for vaccinated travelersâbut thereâs still a lot to consider before deciding to travel to another part of the world. For one, vaccine distribution continues to be uneven, with poorer countries receiving and administering fewer COVID-19 vaccines than wealthier countries. And though fully vaccinated travelers are largely protected from the virus themselves, itâs still not clear the extent to which they can spread the virus to others.
