TAKING the quadrivalent human papillomavirus (HPV4) vaccination is not linked with increased risk of autoimmune disorders in girls, according to researchers.
While several studies have indicated the safety of the vaccine, there are concerns about a possible link to autoimmune disorders, such as lupus, rheumatoid arthritis, Type 1 diabetes and multiple sclerosis.
“In light of these concerns, we wanted to study the HPV4 vaccination,” said Jeffrey Kwong, senior scientist at the Institute for Clinical Evaluative Sciences (ICES).
For the study, published in the journal in CMAJ (Canadian Medical Association Journal), the team looked at data on 290 939 girls, aged 12 to 17 years, in Ontario.
Of the total 180 819 girls, who received the HPV4 vaccination in schoolbased clinics, there were
681 diagnosed cases of autoimmune disorders.
This rate is consistent with the general rate of diagnosed cases in this age group and adds to the body of evidence for the safety of the vaccine.
