Fauci: Perhaps 90% of People May Have Covid Immunity from Either the Vaccine or Prior Infection

TRANSCRIPT:

FAUCI: "I mean, obviously, it would be very important to know the number of people who have been infected in this country. If you do serosurveys and look at the people who have either been vaccinated or who have been infected and have what's called an indication of immunity, which can be easily measured by looking at the antibody response, you are talking about a very, very high percentage of the population, perhaps even as high as 90%. However, one of the things that people need to realize is that immunity wanes. So it isn't like measles. If you measure someone and take a look at their immunity to measles, that lasts a lifetime. The immunity to Covid and SARS-CoV-2 is something that wanes over a period of months. So that’s the wildcard in this, is to be able to predict accurately what level of immunity over time will prevent us from winding up getting either a large surge or a surge associated with hospitalizations."
