Cost-consequences evaluation between bivalent and quadrivalent HPV vaccines in Italy: the potential impact of different cross-protection profiles.
Two human papillomavirus (HPV) vaccines are currently available: a bivalent HPV-16/18 and a quadrivalent HPV-6/11/16/18 vaccine. The vaccines may have different sustained- and cross-protection levels against non-vaccine oncogenic HPV-types. This study investigated the potential difference in clinical and economic impacts provided by two HPV vaccines in Italy. ⋯ Our model suggests that, in the Italian setting, the bivalent vaccine would prevent more precancerous and CC lesions than the quadrivalent vaccine. This translates into a greater cost averted for the bivalent vaccine, which could completely offset savings in GW-related costs associated with the quadrivalent vaccine.
