Background. Human papillomaviruses (HPV) cause several human cancers. Bivalent (Cervarix) and quadrivalent (qGardasil) HPV vaccines both contain virus-like particles of the major oncogenic HPV types 16 and 18, but also cross-protect against some nonvaccine types. However, data on long-term sustainability of the cross-reactive antibody responses to HPV vaccines are scarce.Methods. Serum samples donated 7-12 years after immunization at age 16-17 years with bivalent (n = 730) or quadrivalent (n = 337) HPV vaccine were retrieved from the population-based Finnish Maternity Cohort biobank. Serum antibody levels against HPV types 6, 11, 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68, and 73 were determined using multiplex pseudovirion binding assay. Antibody avidity was assessed using ammonium thiocyanate treatment.Results. Seropositivity for HPV31, 33, 35, 45, 51, 52, 58, 59, 68, and 73 was increasingly common (P
