In this study, it was aimed to prospectively evaluate the efficacy, side effects and seroconversion data of inactive severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), CoronaVac® (Sinovac, China) vaccine in healthcare workers. A total of 1053 healthcare workers who were initially seronegative (COV2T® SARS-CoV-2 Total Siemens, USA) and vaccinated with inactivated SARS-CoV-2 were included in the study. Quantitative IgG antibodies (ADVIA Centaur® SARS-CoV-2 IgG, Siemens, USA) were investigated 28 days after the first vaccine (n= 939) and the second vaccine (n= 771). In addition, neutralizing antibodies were evaluated via "enzyme linked immunosorbent assay (ELISA)" test (ACE2-RBD Neutralization Assay, Dia-Pro, Italy) 28 days after the first vaccine. Antibody response of the vaccine was evaluated statistically by univariate (Chi-square, Fisher's exact test, Student's t test, Mann-Whitney U, one-way ANOVA and Kruskall Wallis ANOVA tests) analysis and linear regression models. The consistency between quantitative IgG test and neutralizing antibody test was also evaluated in blood samples taken 28 days after second vaccination. Statistical analysis was determined in logarithmically transformed data with statistical analysis with SPSS 23.0 and Stata, and type 1 error level was accepted as 0.05. At least one side effect was reported by 31.3% and 26.8% of the participants after the first and second vaccine, respectively. The most frequent side effect was pain at the injection site with a frequency of 20.4% vs 21.7%. The frequency of applying to a health center due to side effects was 1.0% after the first vaccine and 0.8% after the second vaccine. The percentage of those who produced sufficient quantitative IgG was found as 25.3% (95% CI= 22.5-28.1) 28 days after the first vaccine and 97.9% (95% CI= 96.91- 98.93) after the second vaccine. Neutralizing test antibody positivity was found as 97.7% 28 days after the second vaccine. In univariate analysis, the characteristics that significantly increased the quantitative IgG response against inactivated SARS-CoV-2 vaccine were young age (p

Introduction In this study it is aimed to evaluate the prevalence of smoking, factors affecting smoking status, and the attitudes of the elementary school students towards the smoking prohibition law which was approved in July 2009, in city. Materials and Methods The universe of this descriptive study was 6th-7th-8th class, 8236 urban and 4937 semi-urban, total 13.173 elementary schools students in city center. Study population was determined on the basis of a previous study in which the smoking trial prevalence was found 17.5%, 831 students in 6 urban 3 semi-urban, total 9 schools were chosen randomly. A questionnaire was prepared investigating smoking status, the effects of smoking and family history. Among the 9 chosen schools, the questionnaire was applied to 615 students. SPSS 14.0 statistical package was used. Result Forty-seven percentages of the students were female. Prevalence of smoking trial was found 23.5% (16% in urban, 35% in semi-urban schools) while the prevalence of smoking was 7.1% (1.7% in urban, 15.7% in semi-urban schools). Mean age of first smoking trial was 10.04 ± 2.3. The smoking prohibition law was supported by 86.6% of the students, the warnings on the cigarette package was thought to be effective by 43.3% students and 35.2% of the students were exposed to passive smoke. Male gender, social status, education level of the family, smoker family member or close friends were found to be important risk factors for smoking prevalence of the students. Conclusions The early onset of smoking should guide the smoking struggle be concentrated in elementary school especially in semi-urban areas where the smoking prevalence is high.
