Dupilumab safe to continue during vaccine administration in children with AD reveals study
Dupilumab inhibits interleukin (IL)-4 and IL-13 signalling. This monoclonal antibody also acts as an immunomodulator. The current recommendation is to avoid live vaccine administration in dupilumab-treated patients.
A case series involving nine children with severe atopic dermatitis (AD) receiving measles, mumps, and rubella (MMR) vaccine with/without the varicella vaccine in dupilumab clinical trials found no emergence of side effects within four weeks after vaccination. Consequently, the researchers concluded that dupilumab is safe to continue during vaccine administration. This case report is published in Pediatric Dermatology.
In a phase 2/3 clinical trial of dupilumab involving 6-month to 5-year-old children ( subsequently participated in the LIBERTY AD PED-OLE) with moderate-to-severe atopic dermatitis, nine children (protocol deviation) received MMR vaccine with or without varicella vaccine. Five of these children received the vaccine with a ≤12-week gap after dupilumab administration, while four received it >12 weeks after discontinuing dupilumab.
