All of the usual issues apply to this study, so the “findings” are of little to no value.
1. The antibody test used has not been validated, meaning the true accuracy of the results is unknown.
2. It is not known whether or not you can get COVID more than once, so even if the given test was proven to be accurate, it is still not known whether or not a person who was previously exposed could get the disease again and get a more severe case the second time.
3. Like seasonal flu, it is not known whether or not this virus can mutate and therefore exposure would not mean long term immunity.
There seems to be more and more desperate attempts by some to point at every study as “proof” of some kind of “overreaction”. The problem with facing this disease has always been the fact that there are many unknowns that cannot be answered by quick studies. The problems are compounded by the fact that this virus can very quickly ramp up to an overwhelming infection rate, at which point nothing can be done, so the cost of under-reacting is very, very high.
