The window for SARS-CoV-2 antibody tests would be at least 8 months to a year for many individuals.
More expensive tests can detect immunity based on T cells for example, which would provide an even longer window.
And of course really expensive and invasive bone marrow aspirate tests could provide a window approaching a lifetime - but the tradeoffs involved there would likely be unfavorable for practical “proof”. Who knows what technology we’ll come up with in the future though.
