NEIL CAVUTO (HOST): There are a lot more venues -- sports and otherwise -- that require proof that you've been vaccinated. In fact, it's causing, you know, quite the controversy that, you know, at places where they're requiring it for teachers, healthcare workers, and the like. How do you feel about those various mandates?
DR. BOB LAHITA (GUEST): I think the mandates for healthcare professionals are a must. I think for school teachers, professors in colleges, that's a must. You know, we are seeing -- or we are very close, Neil, to herd immunity at this point, with over 75 percent of the population vaccinated. So these mandates did help in that regard. But I don't believe that we should be mandating companies of 100 employees or more because that's bad for business and I think the economy will suffer from that. So we have to be very careful going forward.
