September 11, 2009
The final analysis of the largest efficacy trial of a cervical cancer vaccine was published July 25, 2009, in The Lancet. The study, involving 18,644 women, confirmed GlaxoSmithKline’s Cervarix is highly effective at protecting against the two most common cervical cancer–causing human papillomavirus (HPV) types, 16 and 18. The study also showed that the vaccine provides cross-protection against HPV types 31, 33, and 45, the three most common cancer-causing virus types beyond 16 and 18.
