“Please wait until you’re fully vaccinated before you’re traveling, before you’re engaging in high-risk activities,” said CNN Medical Analyst Dr. Leana Wen. “No doubt when you become vaccinated, the activities that were once higher risk are now going to be lower risk and so just wait until then.”

Wen said she worries the US is on the “precipice” of a fourth surge as data is showing that infections are now skewed toward a younger generation.

Her sentiments were echoed by Dr. Anthony Fauci, who told NBC Nightly News that while he is feeling some Covid-19 fatigue himself, it is important the US continue taking precautions while vaccinating Americans.

“We need to hold out just a bit longer and give vaccines a chance to really get the upper hand in this,” Fauci said. “I’ll guarantee as we get into the late spring and the early summer, you’re going to see a return to gradual degree of normality that everyone is hoping for, but we don’t want to do it prematurely.”
