Common adult vaccinations are not associated with an increased risk of developing rheumatoid arthritis, according to research presented this week at the American College of Rheumatology Annual Scientific Meeting in Atlanta.
Rheumatoid arthritis is a chronic disease that causes pain, stiffness, swelling, and limitation in the motion and function of multiple joints. Though joints are the principal body parts affected by RA, inflammation can develop in other organs as well. An estimated 1.3 million Americans have RA, and the disease typically affects women twice as often as men.
"Vaccinations are among the events which have long been postulated as inciting agents for RA, as well as for many other chronic inflammatory diseases of unknown origin," says Camilla Bengtsson, PhD, an epidemiologist at the Institute of Environmental Medicine, Karolinska Institutet in Stockholm, Sweden, and lead investigator in the study.
"In our case-control study including incident cases of newly diagnosed RA, no increased risk of RA following immunization was observed, at least not in the five years prior to disease onset," explains Dr. Bengtsson, noting that the study is ongoing. "This indicates that immunological provocation with commonly used vaccines in their present form carries no risk of RA in adults."
