>It suggested the neutralization titers were higher, not that they were ineffective. See figure B here taken from the study. That's a large difference to my completely untrained eye. https://twitter.com/AArgoetti/status/1359994177409478656 https://twitter.com/AArgoetti/status/1359994177409478656 >If a delayed person keeps, say, 50% efficacy, and the person with the second dose has 95% efficacy, giving two people 50% efficacy is better than giving one person 95% efficacy. That logic breaks down when the divided efficacy is too low, even if it's formally half of the original. Say efficiency is 33% (and lets pretend the original is 66%). The people who got the 33% efficient vaccine go out and party, balancing out the effect. People think the vaccine doesn't help. Eventually nobody trusts your vaccine, and nobody shows up to get the second dose. I'm not sure 50% is high enough. Maybe it is, but just barely.

> See figure B here taken from the study. That's a large difference to my completely untrained eye. So, LoQ means limit of quantification, aka the threshold below which things can't be measured in their assay technique. I know it's a log scale, but... The study was barely able to detect the response to the baseline variant, so it doesn't take all that much of a drop to escape the study's quantification limit. It's extremely misleading to plot the line all the way down to the bottom of the graph, when all you know is that it is (probably) less than the LoQ line. I say "probably" because this assumes the authors have accurately determined the LoQ, which is easy to mess up. > That logic breaks down when the divided efficacy is too low, even if it's formally half of the original.

  C'ya around. You'll make a fine educator - sure taught me a few things this time.
