New research suggests one dose of an HPV vaccine may be enough to protect against cervical cancer.

The current recommendations call for three doses of the vaccine, but only a small percentage of girls actually complete the treatment.

A study of women in Costa Rica found those who got just one dose of the Cervarix vaccine had stable antibodies against the virus for four years, suggesting it had a lasting effect.

But researchers say it's too soon to change policy guidelines, because they haven't studied the effects of a single dose of the Gardasil vaccine, which is more commonly used in the U.S. and other countries.
