On Monday's "CNN Newsroom," CNN Medical Analyst, ER physician, Milken Institute School of Public Health at the George Washington University Visiting Professor, and former Baltimore Health Commissioner Dr. Leana Wen criticized the CDC's guidelines on what fully vaccinated individuals can do by saying that the advice that fully vaccinated individuals avoid traveling is "far overly cautious in a way that defies common sense." And that she believes fully vaccinated individuals "should be able to travel, should be encouraged to travel."
