Abstract
Objective: It was aimed to explore the correlation between demographic characteristics and the presence of comorbidity in the antibody response after the second dose of vaccination in healthcare workers in this study. In addition, the third and fourth dose approaches of the participants and the protection of the antibody levels formed by the two doses of vaccine against COVID-19 were examined observationally.
 Materials and Methods: Health workers, whose NCP and S protein antibody levels were detected on the 30th day after the second dose of the CoronaVac vaccine, were followed up in terms of being vaccinated for the third and fourth doses and having COVID-19.
 Results: Higher levels of S antibodies were detected in women after two doses of vaccination (p=0.001). It was pointed out that smoking has a negative effect on the antibody response after vaccination (p=0.008). People who had pre-vaccine COVID-19 had higher NCP antibody levels after two doses of vaccination (p=0.013). Of the participants, 152 (97.4%) were vaccinated with the third dose and 110 (70.5%) with the fourth dose.
 Conclusion: The antibody response after two doses of inactivated CoronaVac® vaccination probe is significantly higher in women, younger people, non-smokers, and people who have not been previously infected with the SARS-CoV-2.
