Prime-Boost Vaccination With BNT162b2 Induces High Neutralizing Activity Against SARS-CoV-2 Variants in Naive and COVID-19-Convalescent Individuals.

ABSTRACT:

Background

The objective of this study was to investigate the neutralizing response against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern (VoC) during coronavirus disease 2019 (COVID-19) convalescence and after vaccination.

Methods

COVID-19-convalescent and -naïve individuals were tested for neutralizing activity against SARS-CoV-2 VoC Alpha, Beta, Gamma, and Delta at 1 and 7 months postinfection and 4-6 weeks after BNT162b2 vaccination.

Results

Vaccination induced a high neutralizing response in naïve individuals. Interestingly, vaccination of convalescent patients induced a boosted response that was able to neutralize all VoC at high titers.

Conclusions

Vaccination with BNT162b2 induced high levels of neutralization against
