Medical Research: What is the background for this study?
Response: After the widespread introduction of HPV vaccination of adolescent girls, a number of safety concerns have emerged. In this case, demyelinating diseases, including multiple sclerosis, occurring after HPV vaccination has been reported in social media, news media and medical journals.
Medical Research: What are the main findings?
Response: In a study of almost 4 million Danish and Swedish women, we found no support for an increased risk of multiple sclerosis or other demyelinating diseases following HPV vaccination.
Medical Research: What should clinicians and patients take away from your report?
Response: In this the largest and most comprehensive study to date, there was no support for this particular safety concern. The current evidence suggests that clinicians and patients should not fear demyelinating diseases as a result of HPV vaccination.
Medical Research: What recommendations do you have for future research as a result of this study?
Response: Vaccine safety issues continue to arise. To maintain professional and public trust in routine immunization programs, it is important to address these issues in a timely manner with high quality research.
