Swedish researchers have revealed that vaccines do not appear to increase the risk of rheumatoid arthritis.

The authors report that there was no link between the type or number of vaccines received and the risk of RA.
"This result does not rule out the possibility that vaccinations given earlier in life, or vaccinations that are rare, may trigger the development of RA," Camilla Bengtsson of the Karolinska Institute in Stockholm, Sweden, and colleagues wrote.
The details are due to appear in the journal Annals of the Rheumatic Diseases.
