MMR does not aggravate JIA

The MMR booster vaccination can be safely administered to young children with juvenile idiopathic arthritis (JIA), research shows.

Several cases of athropathy have previously been reported after children with JIA have been administered the rubella vaccination but no controlled reports have established this association.

Now a Dutch study examining the effect of the MMR on 207 children with JIA has found that it does not seem to aggravate the disease.

No increase in flare occurrence or medication use was found in vaccinated children and there was no significant difference between disease activity.

But the authors note that they “cannot fully rule out that there was a small influence of the MMR vaccination on disease activity."
