ABSTRACT
Objective:
We investigated whether there was a difference in the antibody profile after Pfizer/BioNtech vaccination in persons who had already been infected with COVID-19 and those who had not.Method:
Blood samples were obtained before, after the first dose and after the second dose of Pfizer/BioNtech vaccine inoculation in 4 subjects with a history of COVID-19 infection and 62 subjects without a history of COVID-19 infection after obtaining their informed consent. The differences in the antibody titers were examined between those with and without a prior history of COVID-19.Result:
As compared with those without a prior history of COVID-19, those with a prior history of COVID-19 showed significantly higher antibody titers after the first inoculation, and the antibody titers were significantly higher than even those after the second inoculation of subjects without a prior history of COVID-19.
