COVID-19 antibodies disappear within a specific timeframe
Multiple studies demonstrate that COVID-19 antibodies wane over predictable timeframes following infection or vaccination, typically declining significantly within several months.
The claim is specific, empirical, and falsifiable regarding the temporal disappearance or decline of COVID-19 antibodies. Multiple retrieved papers explicitly track antibody dynamics, decay kinetics, and waning over specific timeframes such as 6 to 12 months, strongly supporting the claim. There are no refuting papers.

The study demonstrates that COVID-19 antibody levels consistently decline six months post-vaccination across various vaccine platforms and regimens.

The trial shows that antibody neutralization levels against SARS-CoV-2 variants wane significantly over a 12-month period following vaccination.

The research utilizes longitudinal serological data to specifically model the kinetics and decay rates of neutralizing antibodies following vaccination or boosting.
