Immunity to the infection is not solely determined by antibodies

From September 23, 2020.  Scott Atlas is a national treasure.   

Fascinating blast from the past when mentioning T-cell memory was considered political! Amazing times we've lived through. https://t.co/Z3PkvDTt0T

Immunity to the infection is not solely determined by antibodies.  There is cross immunity from other infections, and there is also T-cell immunity, and the combination of those makes the antibodies a small fraction of the people that have immunity. So the answer is no, it is not 90% of the people who are vulnerable to the infection.
