The first question at today's Senate hearing on coronavirus was about the possibility of college students getting back to campus this fall.
Sen. Lamar Alexander asked Dr. Anthony Fauci what he'd say to school officials who are trying persuade students to come back to campus.
"Let's look down the road three months. There will be about 5,000 campuses across the country trying to welcome 20 million college students," Alexander said.
Fauci said students might feel safest if there was a vaccine for coronavirus — but it's a "bridge too far" to think a vaccine or treatment will be ready by the time classes start this fall.
"If this were a situation where we had a vaccine, that would really be the end of that issue in a positive way," Fauci said. "We don't see a vaccine playing in the ability of individuals to get back to school this term."
Dr. Brett Giroir, with the US Department of Health and Human Services, said the strategy for getting students back on campus is heavily dependent on how much community spread is happening in the fall.
He said there would likely be a "surveillance strategy" for students going back to class. That would involve testing some students at different times "to give an assurance that there's no circulation."
