Coronavirus: small non peer reviewed study suggest low antibody levels in c 1/3rd , esp in the 15-39 age group, who had mild CV
Older people (60-85 age group) markedly higher levels of anti bodies
Relevant to vaccination and immunity certification

This pattern is not unusual in other coronavirus where Antibody levels peak about 2 weeks. Even low levels that persist after these two weeks still provide immunity for about a year.
Annual vaccine boost?

Also. Is there some other function exiting in the young that challenges CV through other means thus somehow meaning that in some groups anti bodies are not produced or only weakly?
I don’t have the expertise to know whether this is even likely or possible.

Clearly an interesting start but a much MUCH bigger study needed and across counties in case different vaccination programmes migh also have had an impact.
On the question of antibody tests, it is also worth remembering that 95% sensitivity levels (which none of the tests undergoing validation here, in Germany or in the Netherlands have achieved) does not mean what you might think.
