The final analysis of the PATRICIA study shows that the HPV-16/18 AS04-adjuvanted vaccine (GlaxoSmithKline) has high efficacy against the precancerous cervical lesions that can eventually lead to cervical cancer. The vaccine also shows cross-protective efficacy against other oncogenic (cancer-causing) HPV types closely related to HPV-16/18. Furthermore, it also shows efficacy in the cohorts relevant to universal mass vaccination and catch-up programmes.
