New research suggests two doses of the HPV vaccine may be enough to protect girls against cervical cancer.

Young women typically get three doses of the vaccine, but the cost of this regimen has made it difficult to implement worldwide.

A Canadian study looked at antibody levels for girls who got the regular three doses of the HPV vaccine and compared them to girls who got only two doses. Those who got two doses had immune responses to the two most common types of HPV similar to immune responses for girls who received three doses.

Researchers say a reduced dose schedule can't be recommended until there's more data on how long the vaccine effectively protects young women.

This study was led by researchers at the University of British Columbia and published in Jama.
