Can you travel on an airplane with out vaccine?

In the states to another state?

To fly to a different country?

What's going on right now with traveling

I now before people could travel with temperature check and Masks on. People should still be allowed to travel even if they don't have the vaccine.

The vaccine is not a cure, the Vaccine does not stop Covid from getting in the body. The vaccine helps your body know how to fight the illness so people don't get severely sick. But even with the vaccine they can still get covid just not serious symptoms.

Anyway the post is not about that.

The Question is can you travel freely now? Are countries open now

Some countries were shut down no one could enter or leave certain cities.
