Dr. Anthony Fauci said the Centers for Disease Control and Prevention was making a “judgment call” on guidance for traveling for people who have received both doses of the coronavirus vaccine because it does not have “data” or “evidence” for some guidance.

“When you don’t have the data, and you don’t have the actual evidence, then you’ve got to make a judgment call,” Fauci said when asked what science the CDC could point to in support of their guidance that fully vaccinated individuals not travel.
