TUCKER CARLSON (HOST): So, does the vaccine -- and there are a couple of them, but do they work or don't they work? It's OK, you can tell us. Well, the CEO of Pfizer came out and seemed to suggest today that actually, the dose that Pfizer is administering doesn't work. The CEO of Pfizer has announced that two doses probably aren't enough. He said it is, quote, “likely that people will need a third dose" of his company's coronavirus vaccine within 12 months of getting fully vaccinated. I guess it's nice to know that now. We didn't know that yesterday.
