Implication

Longitudinal evaluation demonstrates waning yet detectable neutralizing antibodies against SARS-CoV-2 variants six months post-BNT162b2, highlighting the need for strategic booster administration.

Key Points

To assess the persistence and neutralizing capacity of spike protein-specific antibodies against emerging SARS-CoV-2 variants six months after complete BNT162b2 vaccination.
Evaluated circulating antibody levels and neutralization capacity against emerging SARS-CoV-2 variants at a six-month follow-up after two doses of the BNT162b2 mRNA vaccine.
Spike protein-specific and neutralizing antibody titers declined substantially by six months after the two-dose regimen.
Residual antibody levels remained detectable and maintained functional neutralization capacity against emerging SARS-CoV-2 variants of concern.
