Role of recent vaccination in production of false-positive coronavirus antibody titers in cats

J E Barlough et al. J Clin Microbiol. 1984 Mar.

Abstract

Statistical support was obtained for an association between recent vaccination of cats and the presence of elevated background (i.e., anti-cell culture) reactivity in certain of their sera, as detected with a kinetics-based enzyme-linked immunosorbent assay for coronavirus antibodies, implicating routine vaccination as a potential cause of false-positive antibody test results.
