There's convalescent plasma in the study we're all looking at. Looks like a similar difference. - People given AZ required 8.8x the concentration of their serum to neutralize A.30 vs. B.1 - For mRNA vaccines, this was 4.6x. - Convalescent plasma-- those infected-- this was 4.4x. - AZ dose 1, mRNA dose 2 was by far the smallest difference, 1.8x. I'd caution in reading too much into these numbers. Comparing titers in general between the groups in this study is problematic because of vastly varying times since infection/administration. And the size of the populations is small.
