The Role of Immunity in Scrutinizing Omicron Variant

Abstract

Immunology is truly a fascinating discipline that meets the challenge and offers opportunity in ghting and checking the spread of diseases. Many viruses infect humans.The corona virus disease 2019 (COVID-19) pandemic has affected hundreds of millions of people over the world, with more than 4.5 million deaths.The introduction of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) into the human population represents a tremendous medical , economic crisis that remains a world health concern.SARS-CoV-2 infection causes excessive production of pro-inammatory cytokines thereby leading to the development of “Cytokine Storm Syndrome The COVID-19 pandemic triggered an unparalleled pursuit of vaccines to induce specic adaptive immunity, based on virus-neutralizing antibodies and T cell responses.Cytokines are cellular signaling molecules that mediate many biological and immunological actions. Omicron infection can increase immunity against Delta variant, but only if you are vaccinated against coronavirus.
