evidence: But I want to point out one aspect of this that is very interesting. Part of the study was done in South Africa. Although it was relatively small in size, they showed, in the setting of the troublesome B1351 South African variant, that there was six cases in the placebo and zero in the vaccinated group — strongly suggesting the efficacy of the vaccines that we’re using now against problematic variants. [...] And then, finally, what you see here is that in a study of adolescence where — did a study, most recently, in which it was shown to be literally 100 percent efficacy in which 18 cases of COVID-19 was seen in the placebo group and, again, no cases in the vaccine group.
