OBJECTIVE: Both humoral and cellular immunity can be significantly influenced by the immunological responses to vaccination, and both responses are essential. Vaccination is the most consistent, safe, and cost-efficient practice for controlling the COVID-19 pandemic. PATIENTS AND METHODS: Blood samples were collected from participants who received two vaccine doses of COVID-19 Pfizer/BioNTech (BNT162b2) before and on days 7 and 10 after the first and second immunization. We evaluated some hematological and immunological markers responses to the 1st and 2nd doses of the BNT162b2 mRNA (Pfizer/BioNtech) vaccine. RESULTS: In healthy subjects' neutrophil and WBC counts significantly increased compared to those after the first dose. The results of all first-group participant categories demonstrated no discernible variations in lymphocyte counts. There was no change in IgM or IgG in all second- group cohorts, except for a considerable rise in IgG levels in people with a history of coronavirus infection following the second dosage compared to baseline. After the second dose, CD4+ T-cell and CD8+ T-cell levels rose in all groups compared to before the immunization and after the first dosage. Data demonstrated a sub-stantial rise in neutrophil-lymphocyte ratio (NLR) after the second dose of the vaccine. Individuals who had previously had COVID-19 disease experienced a considerable increase in C3 and C4 levels after the first and second dosages compared to baseline. Additionally, compared to their levels after the first dosage, C4 levels increased significantly following the second dosage. Interleukin (IL)-6, IL-15, macrophage colony-stimulating factor (M-CSF), granulocyte colony stimulating factor (G-CSF), interferon gamma-induced protein 10 (IP-10/CXCL10), and macrophage inflammatory protein-1 alpha (MIP-1α/CCL3) levels were increased after boost correlated with Spike antibody levels, supporting their utility as indicators of successful humoral immunity development in response to vaccination. CONCLUSIONS: We can conclude that the Pfizer/BioNTech vaccine produced a more potent T-cell response than humoral ones. [ABSTRACT FROM AUTHOR] |
