Speaking on Fox News on Tuesday, Carlson said: "If the vaccine is effective, there is no reason for people who have received the vaccine to wear masks or avoid physical contact. "So maybe it doesn't work, and they're simply not telling you that." Fauci addressed Carlson's comments in an interview with CNN, saying: "That's just a typical crazy conspiracy theory. Why would we not tell people if [the vaccine] doesn't work? Look at the data. The data are overwhelming. "In the three vaccines that have been approved for use in an emergency use authorization—the J&J, the Pfizer and the Moderna—you had 30,000 [Moderna], 44,000 [Pfizer] and 40,000 [J&J] people in the clinical trial with an overwhelming signal of efficacy.
