New American research has found that just a single dose of the human papillomavirus (HPV) vaccine appears to be as effective in preventing preinvasive cervical disease, which can develop into cervical cancer, as multiple doses.

Carried out by researchers at The University of Texas Medical Branch at Galveston, the new study looked at 133,082 females aged nine to 26, who were matched for age, sexually-transmitted disease history, and pregnancy.
