After six to eight days, the adaptive immune response begins and is specific to the infection. It involves two types of white blood cells: T cells (cellular response) and B cells (antibody response).
Generic reaction to ANY infection; Innate immune response cells generate interferons1 and other substances (cytokines); Interferons prevent virus reproduction; Phase 2 is triggered; Innate immune response.
The body's defense against viral infections
At this stage, infection in phases one and two can be stopped.
1. The early signs of infection, such as fever and muscular pains, are brought on by interferons and cytokines.
2. The adaptive response could not be stimulated right away if the innate reaction is "weaker" in some individuals (such as the elderly or those with underlying health issues).
