If SARS-CoV-2 immunity is similar to other severe coronavirus infections like SARS-CoV-1 immunity, that protection could last at least 17 years. However, tests to measure cellular immunity are.
Much of the study on the immune response to SARS-CoV-2, the novel coronavirus that causes COVID-19, has focused on the production of antibodies.

A positive antibody test result may indicate previous or current exposure to an illness but should NOT be used to infer immunity status or infectivity. It is unknown whether COVID-19 antibodies indicate protective immunity and for how long. A negative test result does not rule out the possibility of an infection with SARS-CoV-2 The T cell test is intended to detect a T cell-mediated immune response to Covid-19, which is different to serology which looks for an antibody response. T cells and antibodies are two arms of the adaptive immune response. The detection and measurement of each can provide different information about disease activity and an individual's immune.
