CDC：打完疫苗的人美国国内旅行不必再测核酸、回家后不必隔离

The CDC says when people who are fully vaccinated travel within the U.S., they no longer need to get tested before or after their trip, unless their destination requires it.

They also don’t need to self-quarantine when they return home, as long as precautions like mask-wearing and social distancing are taken.
