Multicenter StudyEarly antibody response in health-care professionals after two doses of SARS-CoV-2 mRNA vaccine (BNT162b2).
Data on the immune response after two doses of BNT162b2 are so far limited. Previously infected individuals were excluded from pivotal clinical trials and the optimum dose regimen in this population has not been clearly studied. The CRO-VAX HCP study aims to investigate the early antibody response in a population of health-care professionals having received two doses of the BNT162b2 mRNA coronavirus disease 2019 (COVID-19) vaccine. ⋯ This study supports the concept that a single dose of BNT162b2 would be sufficient in previously infected individuals.
