Not all virus infections produce a protective immune response in this means. HIV evades the immune system by constantly changing the amino acid sequence of the proteins on the floor of the virion. This is known as “escape mutation” because the viral epitopes escape recognition by the host immune response.
Examples of nucleoside analogues are aciclovir for Herpes simplex virus infections and lamivudine for HIV and hepatitis B virus infections. Aciclovir is likely one of the oldest and most regularly prescribed antiviral drugs.Other antiviral medication in use goal completely different phases of the viral life cycle.
