The whole context:
In an interview on NBC's "Today Show," Matt Lauer asked Mr. Biden, "If a member of your family came to you . . . and said, 'Look, I want to go on a commercial airliner to Mexico, and back within the next week,' would you think it's a good idea?"
That is A PERSONAL QUESTION... not a MEDICAL QUESTION! He's asking him WHAT he'd DO with HIS FAMILY.
The vice president replied, "I would tell members of my family -- and I have -- I wouldn't go anywhere in confined places now. . . . It's not that it's going to Mexico. It's [that] you're in a confined aircraft. When one person sneezes, it goes all the way through the aircraft. That's me." He added, "So, from my perspective, what it relates to is mitigation. If you're out in the middle of a field when someone sneezes, that's one thing. If you're in a closed aircraft or closed container or closed car or closed classroom, it's a different thing."
He's talking about WHAT HE'D do with HIS FAMILY, not for the public. Not you.
