New data from an extended follow-up study show that GlaxoSmithKline PLC.’s cervical cancer candidate vaccine, Cervarix, generates sustained high levels of neutralizing antibodies against the two most common cervical cancer-causing virus types for up to 6.4 years. This is the longest duration of sustained neutralising antibody levels reported against both virus types HPV 16 and 18 with a cervical cancer vaccine to date. Experts believe that neutralizing antibodies are essential for protection against cervical cancer.

New data related to GlaxoSmithKline’s CERVARIX(R) demonstrates that the cervical cancer candidate vaccine provides significant protection for women against the four most common cancer-causing human papillomavirus types. The vaccine gives protection for nearly six and a half years, which is the longest duration of protection reported to date. During this period, the vaccine showed 100% efficacy in preventing precancerous lesions due to cancer-causing virus types 16 and 18 as well as provided substantial protection against infection caused by virus types 31 and 45.
