The last paragraph of the WaPo article we are all commenting on:
“South Africa has a quite high seroprevalence of prior infection, particularly after delta, and in some parts of South Africa up to 80 percent of people were exposed to previous infection,” she said. “We don’t think it’s a question of virulence, but more a question of exposure to vaccination and prior infection, so we would be cautious to try and interpret that this is a less virulent strain. We’ll have to see what happens in other parts of the world before we make a call on this.”
- GeekyBear 5y agoA study was done testing samples pulled from ~1.5 million blood donations in the US looking for Covid antibodies. >By May 2021, the combined infection- and vaccination-induced seroprevalence estimate increased to 83.3% (95% CI, 82.9%-83.7%) https://jamanetwork.com/journals/jama/fullarticle/2784013 https://jamanetwork.com/journals/jama/fullarticle/2784013 The delta variant surge didn't hit the States until after this study concluded, so one would expect the numbers to be quite a bit higher today.
