Frequency of sars-cov-2 infection and covid-19 vaccine uptake and protection among Syrian refugees: covid-19 vaccine among Syrian refugees. BMC Infectious Diseases, 24(1). http://dx.doi.org/10.1186/s12879-024-09460-41471-2334http://dx.doi.org/10.1186/s12879-024-09460-4https://hdl.handle.net/20.500.12511/12653It is aimed to examine the frequency of COVID-19 disease, the rates of COVID-19 vaccination and the vaccine effectiveness (VE) among Syrian refugees. It is a retrospective cohort study. Syrian refugees aged 18 years and above registered to a family health center in Sultanbeyli district in Istanbul were included. Vaccine effectiveness were calculated for both Pfizer BioN-Tech and CoronaVac (Sinovac) vaccines. The data of 2586 Syrian people was evaluated in the study. The median age of the participants was 34.0 years (min:18.0; max: 90.0). Of the participants 58.4% (n = 1510) were female, 41.6% (n = 1076) were male. In our study of the refugees 15.7% had history of COVID-19 infection. Refugees having full vaccination with Biontech and Sinovac have a significantly lower COVID-19 infection rate than those without vaccination (HR = 8.687; p < 0.001). Adjusted VE for Biontech, Sinovac, and both were 89.2% (95.0% CI:83.3–93.1), 81.2% (95.0% CI:48.72–93.1) and 88.5% (95.0% CI:82.7–92.3), respectively. The results of the study highlight the importance of vaccinations against COVID-19 pandemic, since both vaccines were highly protective in refugees.enAttribution 4.0 Internationalinfo:eu-repo/semantics/openAccessCOVID-19 InfectionRefugeeSyrianVaccinationVaccine EffectivenessArticle24110.1186/s12879-024-09460-4Q20012440032000022-s2.0-8519553356038851672Q1
