The humoral response to Gardasil® over four years as defined by Total IgG and competitive luminex immunoassay

Abstract

Safe and effective vaccines against anogenital human papillomaviruses (HPV) are now available. These vaccines, composed of virus-like particles (VLPs) made from the L1 major capsid protein of specific HPV types, induce a polyclonal antibody response directed against specific conformational and linear epitopes displayed on the VLP. Numerous studies indicated the importance of neutralizing antibodies in protection from infection. However, our understanding of the antibody responses to these vaccines is not complete, and there is no established immune correlate of protection nor antibody threshold that correlates with protection against HPV infection or disease. In the current study, antibody r..
