ANTHONY FAUCI: The dynamics of COVID-19 outbreak, as Dr. Walensky just showed you a moment ago, continue to point in a sharp downward direction. Vaccination and boosting will be critical in maintaining that downward trajectory, particularly when you're talking about the red curve of severe disease leading to hospitalization.

And getting back to the first question that I posed in my first slide, the potential future requirement for an additional boost or a fourth shot for mRNA or a third shot for J&J is being very carefully monitored in real time. And recommendations, if needed, will be updated according to the data as it evolves.
