Summary
This study is checking how long the HPV vaccine protects women who received one, two, or three doses. Researchers are following about 946 women from an earlier trial in Costa Rica for up to 20 years after their shots. By testing blood samples, they hope to learn if one dose might be enough to prevent HPV-related cancers.
