A new study suggests the quadrivalent vaccine against human papillomavirus (qHPV) may increase the risk of developing several autoimmune diseases.
A retrospective cohort study published on March 7 in Vaccine found that adolescent women who were vaccinated were 4.4 times more likely to develop rheumatoid arthritis than those who were not vaccinated. Similarly, vaccinated adolescent women had a 2.76 times higher chance of developing juvenile idiopathic arthritis.
