MADRID – Administration of live attenuated booster of the MMR vaccine with or without varicella (MMR/V) was not associated with serious adverse events in children on immunosuppressive therapy for a rheumatic disease, according to data presented at the European Congress of Rheumatology.
“The study implies that patients can receive booster vaccinations regardless of age, diagnosis, or therapy,” reported Veronica Bergonzo Moshe, MD, a pediatric rheumatologist at Meir Medical Center, Kfar Saba, Israel.
In the absence of safety data, the vaccination of children with rheumatic diseases taking immunosuppressive therapies has been controversial. Although these children face communicable and sometimes life-threatening diseases without vaccination, many clinicians are not offering this protection because they fear adverse consequences.
Current Paediatric Rheumatology European Society (PReS) guidelines have been equivocal, recommending that vaccines be considered on a “case-by-case basis” in children with a rheumatic disease if they are taking high doses of disease-modifying antirheumatic drugs (DMARDs), glucocorticoids, or any dose of biologics.
“The fear is that a state of immune suppression might decrease response to the vaccine or lead to a flare of the rheumatologic disease,” Dr. Moshe said.
In the retrospective study presented by Dr. Moshe, data were collected on 234 children with rheumatic diseases who received a live attenuated MMR/V booster. The children were drawn from 12 pediatric rheumatology centers in 10 countries.
In this relatively large series, 82% of the children had oligoarticular or polyarticular juvenile idiopathic arthritis (JIA). A range of other rheumatic diseases, including juvenile dermatomyositis, localized scleroderma, and isolated idiopathic uveitis were represented among the remaining patients. All were taking medication, and 48% were in remission.
When broken down by therapy, there were three localized reactions in 110 (2.7%) children who received the booster while on methotrexate. No other adverse events, including disease flare, were observed.
Similarly, six of the seven adverse events observed in 76 (8%) patients who were taking methotrexate plus a tumor necrosis factor (TNF) inhibitor biologic at the time of vaccination were local reactions. Fever was reported in one patient. All of these events were transient.
In the 39 patients taking a TNF inhibitor alone, there was a single case of transient fever. There were no adverse events reported in the three patients vaccinated while on tocilizumab, seven patients while on anakinra, or five patients while on canakinumab.
Following vaccination, there were no signs of symptoms of the diseases that the vaccines are designed to prevent. In the minority of patients who did develop localized reactions or fever in this series, there was no apparent relationship with disease activity, age, or sex when compared to those who did not develop an adverse event.
These retrospective data are not definitive, but they are reassuring, according to Dr. Moshe. A larger prospective study by the PReS vaccination study group is now planned. The issue of leaving children unvaccinated is topical due to the recent outbreaks of measles in the United States.
“We must have clear guidelines on how to deal with the administration of live vaccines in this patient population so that we can provide the safest and most effective practice,” Dr. Moshe said.
These data are a first step.
“This large retrospective study demonstrates that live attenuated booster vaccine is probably safe in children with rheumatic diseases,” said Dr. Moshe, but she deferred to the PReS guidelines in suggesting that the decision to vaccinate still might best be performed on a case-by-case basis.
