EXCERPT:
CAPLAN: "Well, remember, vaccine passports or even vaccine requirements do depend on access. It's hard to impose anything unless you are pretty sure that somebody can get a vaccine. So I think it will be a little while before we see this, let's say, within the U.S. But there are going to be communities and areas of the country where it starts to make sense, due to high availability of vaccine, to say, 'You want to come back to work in person? You've got to show me a vaccine certificate. You want to go in a bar, a restaurant? You've got to show me a vaccine certificate.' I think there will be some inequality in the U.S., but hopefully it will wash out quickly as the supplies increase very rapidly. And I think they are going to. It also gives you an incentive to overcome vaccine hesitancy. Some people are not sure, still, whether they want to do the vaccine. But if you promise them more mobility, more ability to get a job, more ability to get travel, that's a very powerful incentive to actually achieve fuller vaccination.”
