Comparative Study of Patterns of Immune Response to COVID 19 Vaccination

An effective vaccine stands as the most effective way for controlling the COVID 19 pandemic , yet, immunogenic vaccine efficacy needs to be extensively studied . T cell responses against the structural proteins have been found to be the most immunogenic in peripheral blood mononuclear cells of convalescent SARS-CoV1 patients which needs to be tested in SARS -COV2 vaccine efficacy studies alongside with the sustainability of humoral and cellular immune responses . Clinically , immunocompromised patients face drastic outcome of infections , which led the Advisory Committee on Immunization Practices (ACIP) - USA -and the Joint Committee on Vaccination and Immunisation (JCVI) -UK- recommend COVID-19 vaccination of immunocompromised , the WHO Strategic Advisory Group of Experts on Immunization (SAGE), recommended that the three vaccines(Pfizer ,Moderna and Astra Zeneca) can be used for individuals with high-risk comorbidities . Nevertheless, there is an unmet research need concerning the immune response towards COVID 19 vaccination in this population . Based on the previous work of our team in designing B and T cell epitopes distributed over the S protein , we will study the immune response in the available vaccines in Egypt.
