Biochemical Study for The Effect of Pfizer‐BioNTech COVID‐19 Vaccine

The present study aimed to evaluate the biochemical effect of COVID-19 vaccines (Pfizer‐BioNTech COVID‐19 vaccine). 90 samples were included in the study from people in the vaccine center in Al-Dhuluiya general hospital-Salah Al-Din who was vaccinated with the Pfizer vaccine during the period from 1/11/2021 until 1/2/2022. The samples were collected before receiving the 1st dose and after 24-48 hours of taking the 1st and 2nd doses. The collected samples were divided into three groups: -First group-G1: Before taking the first dose of the Pfizer vaccine, -Second group-G2, and Third group-G3: After taking the first and second doses of the Pfizer vaccine respectively. The study includes the determination of different biochemical parameters such as serum Troponin, Lactate dehydrogenase-LDH, D-dimer, Lipid profiles (Cholesterol, Triglycerides, High-density lipoprotein cholesterol-HDL-C, Low-density lipoprotein cholesterol-LDL-C), Total iron, Transferrin, ferritin, Glutathione-GSH, Malondialdhyde-MDA, and peroxy nitrate-PON.
