A single HPV vaccination appears just as effective as two doses at preventing the viral infection that causes cervical cancer, researchers reported Wednesday.  HPV, or human papillomavirus, is very common and spread through sex.  Most HPV infections clear up on their own but some linger, causing cancers that appear years later, including cervical cancer in women and rarer cancers in both women and men.
