That's interesting. If that bears out, it suggests without antibody immunity people will get infected by COVID. However, that same study also shows that the vaccine still prevents serious illness and death, i.e. those other immunity mechanisms are still there and effective, just not kicking in quickly enough to block infection. So "lose more than 80% of their COVID-19 immunity" is still misleading.
