We report neutralizing antibody titers (NAbTs) elicited by CoronaVac and BNT162b2 vaccines in healthcare workers with and without prior SARS-CoV-2 infection using both a pseudotype-based assay and a commercial kit. NAbTs were higher for the mRNA vaccine and increased in all previously infected. Good correlation between both assays was found.
