If sustained at that rate, the antibodies would disappear within about a year.
What is a good Covid antibody count?
“You’re more protected at 2,500 than at 1,000. It’s up to you and your risk of exposure, your risk of severe disease, all of those things together, to know whether you need to be at greater than 1,000 or if 1,000 is fine for you.”
