False COVID-19 cases due to contamination by inactivated virus vaccine.


ABSTRACT: A false-positive SARS-CoV-2 RT-PCR result can lead to unnecessary public-health measures. We report two individuals whose respiratory specimens were contaminated by inactivated SARS-CoV-2 vaccine strain(CoronaVac), likely at vaccination premises. Incidentally, whole-genome sequencing of CoronaVac showed adaptive deletions on the spike protein, which do not result in observable changes of antigenicity.
