Bivalent HPV vaccine outshinesquadrivalent vaccine?

In Italy, a bivalent human papillomavirus (HPV)vaccine may be associated with a greater reduction inprecancerous and cervical cancer lesions than aquadrivalent HPV vaccine, resulting in a greater avertedcost for the bivalent vaccine, suggest researchers fromItaly and Belgium.*

The researchers used a prevalence-based model toevaluate the incidence of HPV-related lesions andassociated costs averted with the use of a bivalentHPV-16/18 vaccine [Cervarix], compared with aquadrivalent HPV-6/11/16/18 vaccine [Gardasil]. TheHPV-related lesions included in the study wereabnormal Pap smear, cervical intraepithelial neoplasia(CIN), cervical cancer, and genital warts. The costanalysis was conducted from the Italian NHSperspective.

The results of the study indicate that the bivalentvaccine would prevent more abnormal pap smears,cervical cancer, CIN1, and CIN2/3 lesions than thequadrivalent vaccine; the quadrivalent vaccine wouldprevent more genital warts cases than the bivalentvaccine. According to the results, the prevented cases ofcervical cancer and genital warts associated with eachvaccine would have the greatest effect on the total costaverted. The model estimated that the bivalent vaccine,compared with the quadrivalent vaccine, would result inan additional cost** averted of €2 385 354 per year.* This study was funded by GlaxoSmithKline Biologicals** 2010 values
