"T cell responses may be more sensitive indicators of SARS-Co-V-2 exposure than antibodies. ... data relying only on the detection of SARS-CoV-2 antibodies may lead to a substantial underestimation of prior exposure to the virus" @FafiKremer https://www.medrxiv.org/content/10.1101/2020.06.21.20132449v1 …

Is antibody creation influenced by age? Or how does it explain the Spanish data? I don’t understand how it facilitates spread under the radar either. (This is not my field...)
Maybe, or, a younger people have a different type of immune response, or, innate immunity is more common in younger people. There is a lot we do not know, but since higher exposure is an unlikely explanation, it is clear that antibodies do not tell the whole story.

There seems to be a strong correlation between asymptomatic COVID and age. I guess symptom severity could be correlated with level of antibodies? https://arxiv.org/pdf/2006.08471.pdf …pic.twitter.com/m8rCsIQAXF

I don't know much about age-effect on innate immunity - but we have seen that live MMR provides non-specific protection against other infectious diseases, and it would be interesting to follow-up!
