The FDA today approved the human papillomavirus (HPV) vaccine Cervarix for use in girls and young women ages 10-25 to help prevent cervical cancer.
Cervarix targets two HPV strains, HPV 16 and HPV 18, which are leading causes of cervical cancer. Cervarix is approved to help prevent cervical precancers and cervical cancers associated with those two types of HPV.
HPV infection is common; the virus is sexually transmitted. Most women who get infected don’t develop cervical cancer, and there are other causes of cervical cancer.
In clinical trials, Cervarix was shown to be 93% effective in preventing cervical precancers associated with HPV 16 or HPV18 in women with no evidence of current or previous infection with one of those two HPV types, according to GlaxoSmithKline, the drug company that makes Cervarix.
