As a complex immune organ, the skin plays a major part in protecting the body against viruses. Innate immunity involves an early response to foreign antigens but is not pathogen specific, whereas an adaptive response is specific for antigen recognition and develops memory but takes longer to activate. Viruses have developed methods to evade the skin immune response in order to establish infection or release their progeny. Vaccines can protect against viruses by helping to produce a rapid immune response, with high levels of protective antibodies for their target viral antigens.
