Cervical cancer affects more than half a million women and causes more than a quarter of a million deaths globally.
Cervical cancers result from a human papillomavirus, or HPV infection.
HPV infections can cause cancers in other parts of the body, the latest HPV vaccine could prevent infections and many cancers.
The HPV vaccine could prevent up to 90 percent of HPV-related cancers, the vaccine can prevent HPV infection if the vaccine is given before exposure to any of the HPV types that the vaccine protects against.
Different formulas of the HPV vaccine protect against different types of HPV. Only two types, HPV16 and HPV18, cause 70 percent or more of all invasive cervical cancers and all HPV vaccine formulas protect against these two.
The nonavalent formula of the HPV vaccine is the most protective: it protects against HPV16, HPV18 and five other cancer-causing HPV types.
Experts estimate that the nonavalent HPV vaccine could reduce HPV-related cancers worldwide by 90 percent or more if the entire global population received it.
