After Coronavirus infection, the natural reaction of our body is to develop antibodies against COIVD-19 and keeps a memory of it.<\/p>\n
According to the National Institute of Health<\/a>, immune cells of the body along with immunity proteins keep circulating in the human body. When the coronavirus had a chance to see one of our immune cells or proteins, these proteins and immune cells tend to kill it thereby decreasing the severity of the illness.<\/p>\n Whether you are suffering from COVID-19, recovered it, received a vaccine against it or remained untouched by the virus during the whole pandemic, understanding the natural reaction of our body after COVID-19 is helpful in any case.<\/p>\n So, the natural reaction of our body after COVID-19 has many aspects. Two types of immunity are involved in responding to the infection. one is natural immunity and the other one is vaccine-induced immunity. This article is about natural immunity.<\/p>\n The human body develops all the components of its immune system even after getting recovered from it i.e. antibodies, helper T cells, Kill T cells, and B Cells.<\/p>\n Antibodies are the immunoglobulin proteins that are continuously circulating in our blood and looking for foreign particles like bacteria or viruses. Helper T cells recognize the foreign particle, killer T cells, as the name indicates, kill them and last but not least B cells keep a memory of the virus and make antibodies on a second infection.<\/p>\n Now, the question is how long immunity against COVID_19 lasts?<\/p>\n\n
