En interferonburen motståndskraft syns ju inte i serologi.
But the first serological tests were taken before the timeframe established in which these antibodies would reasonably fade in a population. We can therefore determine that the rate of asymptomatic/very mild cases that have since lost their antibodies is relatively low and likely only a few percentage at the maximum.
Cross-reactive T-cells grant no immunity and it remains to be seen whether or not people have actually defeated the virus without producing antibodies (unlikely) and if so, whether this grants any mitigating attributes for future infections (unlikely).
