The CDC is issuing a message to think twice about traveling over the long Labor Day weekend if you have not gotten a vaccine.

"We have actually articulated that people who are fully vaccinated, who are wearing masks can travel. Although given where we are with disease transmission right now, we would say that people need to take these risks into their own consideration as they think about traveling first and foremost, if you are unvaccinated, we would recommend not traveling," says CDC Director Rochelle Walensky.

As of this week, the CDC reports 203 million American people have received at least one dose of a COVID-19 vaccine.
