The immune cells involved in the immune response is the adaptive immune cells because once you get it once, you can't get it again.

How the virus repicates

When the virus enters the host cell, it loses its capsid and the RNA induces the host cell to produce viral poly-protein without shutting of protein synthesis. With the viral proteins, a protease for the making of structural proteins and a polymerase for the replication of viral RNA which become encapsulated into new viruses. It is the lyctic cycle.
