This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Amid pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), vaccination is hailed as one of the most effective preventive measures. An mRNA vaccine termed BNT162b2 showed satisfactory safety and efficacy in the clinical trials but several issues including variability in the individual immune response or determination of target antibody titre that exerts sufficient immune protection needs to be assessed for planning a more efficient vaccination strategy. By monitoring IgG titres before and two months after the initial administration of BNT162b2 in 655 healthcare workers by Abbott IgG II quant that detects IgG against the receptor-binding domain in S protein of SARS-CoV-2, we confirmed that hypertension, dyslipidaemia, chronic kidney disease and use of immune suppressant in addition to male gender, advanced age, and absence of previous infection were significantly associated with low antibody response to the vaccination.
