Risk Factors of COVID 19 Vaccination

Abstract

Vaccines prevent the spread of contagious and deadly diseases. The early and nonspecific innate immune response, which can cause adverse effects like tiredness, malaise, and irritability, causes inflammatory markers to rise within hours following vaccination. The inflammatory reaction, as the first stage of the immune response, normally lasts a few days but can last longer in some people, such as those who are depressed. The adaptive immune system is in charge of the immune response's second prong. Because it focuses on certain vaccine components, it takes longer to deploy. Vaccines are intended to imbue the adaptive immune system with a long-term memory of viral or bacterial components, allowing it to respond rapidly and efficiently when challenged with infections. The adaptive immune system responds to the vaccination by (a) multiplying T cells, which can be programmed to recognize and kill pathogen-infected cells, and (b) producing antibodies, which are proteins that neutralize viruses and bacteria.
