Swedish study links HPV vaccination to reduced preterm birth risk
A large-scale study conducted by the Karolinska Institute in Stockholm suggests that HPV vaccination may provide benefits beyond preventing cervical cancer. Research published in The BMJ, analyzing data from 624,713 first-time births in Sweden between 2006 and 2023, indicates that vaccinated women experienced fewer pregnancy complications.
Specifically, women who received the HPV vaccine were found to have a lower incidence of preterm births (under 37 weeks), very early preterm births (28–31 weeks), spontaneous preterm births, and premature rupture of membranes. The study also noted a lower frequency of severe malpresentations involving low birth weight or length.
The findings suggest that the protective effects are more pronounced when the vaccination occurs during adolescence. Approximately 14.8% of the pregnant women in the study cohort had been vaccinated with a quadrivalent HPV vaccine prior to pregnancy.
