CDC: Fully vaccinated people can travel in U.S. without tests or quarantines

People who are fully vaccinated against Covid-19 can travel freely in the U.S., as long as they remain masked on planes, buses and trains, the Centers for Disease Control and Prevention announced Friday.

It is unclear how much impact the new guidance will have. People are already traveling and making decisions on their own. American Airlines reported Monday that the company's bookings have jumped to 90 percent of what they were before the pandemic.

The new guidance means that "fully vaccinated grandparents can fly to visit their healthy grandkids without getting a Covid-19 test, or self-quarantining, provided they follow the other recommended prevention measures," CDC director Dr. Rochelle Walensky said Friday during a news briefing.

Still, the number of Covid-19 cases continues to rise. The current seven-day average of new cases is slightly above 62,000 cases per day.
