据说疫苗可能会导致测试结果单阳

Pfizer-BioNTech COVID-19 vaccine contains mRNA that encodes the spike protein; thus, a
positive test for spike protein IgM/IgG could indicate either prior infection or vaccination
– To evaluate for evidence of prior infection in an individual with a history of Pfizer-BioNTech
COVID-19 vaccination, a test specifically evaluating IgM/IgG to the nucleocapsid protein should be used
