ABSTRACT
The study was designed to evaluate the medical relevance of interleukin-13 levels (ILs-13), and total antioxidant capacity (TAC) in coronavirus disease 2019 (COVID-19) groups, cured groups, control groups;before and after taking the vaccine. Blood samples were taken from Oncology Unit in Al-Mahaweel hospital in Hilla city. Sixteen patients, sixteen cured patients, thirty control, sixteen subject were taken one dose of Pfizer vaccine, and sixteen subject were taken two doses of Pfizer vaccine. We found that significantly with COVID-19 patients Low level mean of IL-13 compar with group (cured patients, receiving dose 1, receiving dose 2), In cured group increase the level of IL13,in groups receiving dose 1, receiving dose 2 high level to mean compared with group Cured patients and Covid-19 patients,total antioxidant capacity (TAC) decreased in patients when compare with the control groups, increase TAC levels in cured patients when compare with COVID-19 patients,, it is found that subjects were taken one dose or tow dose of Pfizer vaccine have more TAC levels than COVID-19 vaccine for that reason the Pfizer vaccines play the important role in activity of immune systems. © 2022, ResearchTrentz Academy Publishing Education Services.
