Norwegian Institute of Public Health -- Chronic human papilloma virus (HPV)-infections can lead to cellular changes in the cervix that can be a pre-stage to cervical cancer. Surgical treatment of these pre-stages gives an increased risk of preterm birth in subsequent pregnancies. As the HPV-vaccine can prevent pre-stages of cervical cancer, it may therefore reduce the number of preterm births. A new Norwegian study has calculated the benefits of HPV-vaccination.
