Transcript of the 162nd meeting of Vaccines and Related Biological Products Advisory Committee (VRBPAC)

Dr. Moore: "One question... I find is really, really central, and important, is that FDA did not ask in its guidance and Pfizer has presented no evidence in its data today that the vaccine has any effect on virus carriage or shedding, which is the fundamental basis for herd immunity. And so even though the individual efficacy of this vaccine is very, very, very high, we really, as of right now, do not have any evidence that it will have an impact, social wide, on the epidemic...

[I]t is so important as of right now as to whether or not this vaccine can have an impact on the non-vaccinated persons who are at risk for acquiring infection. We don’t know that."
