It seems like a broken record but you don't need active antibodies to have protection from the vaccine. Antibodies give you protection in that moment. If you have no antibodies, you are extremely likely to test positive because the virus -- temporarily -- can freely enter your cells and replicate. However, other immune system components quickly identify the invader, re-boost antibodies, and crush the infection. Expecting the vaccine to produce high antibody counts for life is not how our immune systems work.
