Unfortunately there is some pessimism about whether a coronavirus vaccine is likely to provide "sterilizing immunity" which would prevent spread, as opposed to just reducing the severity of the disease. https://www.statnews.com/2020/05/22/the-world-needs-covid-19-vaccines-it-may-also-be-overestimating-their-power/ https://www.statnews.com/2020/05/22/the-world-needs-covid-19...
- ummonk 6y agoWould this mean we are having a bunch of asymptomatic reinfections resulting in retransmission? Surely we would have seen a lot of examples of this already with test and trace?
- ptaipale 6y agoI'm a complete layman here, but I would expect that the "prevent spread" is not binary, it's a spwetrum [0,1]. Thus, even if it does not completely prevent spread, if just a part, or even a smallish part, is prevented, that also helps others. (Same thing in mask discussion. Lots of people dismiss masks because they may not completely prevent an infection; that is stupid, because masks still decrease the probability of infection (and more importantly, spreading to others).
