Vikrant Patil, Sushama Patil
Immune response to the infection is double edged sword, under expression as well as over expression of immune response is lethal. Over activation of immunity and inflammation can cause a lung injury thus can be correlated to severity of COVID 19. Acquired immunity is a result of natural infection or through immunization with a vaccine. Immunity within a population possess down or halt the infection. It refers to the herd immunity. The re-exposure to the individuals to virus will produce more robust antibody response over period of time. The herd immunity is seeming very destructive, but is very robust response that a community will develop against COVID 19 eventually through socialization of infected individuals and immunization. The robust immune response would get developed to reinfection and memory immunity. Herd immunity is light after a long tunnel and can help nations to operate to the normalcy of functioning.
