This isn't quite true. What is true is that there is no information out there to conclusively support long term retention of antibodies, in large part because we've only got 6 months of data.
As to the latter point, I wonder about the trial design. If they didn't give all participants a Covid antibody test before starting, it is very likely that several participants were previously infected. Smaller sample size though.

- rkangel 6y agoThere's always some criteria for the test group. An example might be: Age 20-65, BMI below 2, with no long term medical conditions You find enough people that fit that group and then randomly divide them into two groups, one of which is the test group and one the control. It is possible but unlikely that the criteria includes "has not previously had Covid 19". Assuming the criteria didn't include that, then some of the participants and some of the control group will have previously had Covid, and so we now have some evidence as to whether a cytokine storm occurs.
