MMR vaccine "safe" for egg allergic children

Experts have failed to find any evidence that the MMR vaccine should not be given to children with egg allergies.

The Paediatric Allergy Group of the British Society for Allergy and Clinical Immunology has reviewed the evidence that egg allergy can pose a problem due to the MMR vaccine being cultured on embryo chick fibroblasts.

They found, however, that traces of hen's egg protein in the vaccine are too low to trigger an allergic reaction.

The uptake rate of MMR has remained low in part due to the belief that children with egg allergy cannot be given MMR.

But the Paediatric Allergy Group now recommend that MMR can be administered safely to all egg-allergic children in primary care, without any special precautions.

Professor John Warner, chair of The BSACI Paediatric Allergy Group and Professor of Paediatrics at St Mary's Hospital, London said: "Egg-allergic children who have not had problems with other vaccinations can safely be given MMR in primary care.

"Specialist assessment is only required if any previous vaccinations have resulted in a severe allergic reaction (including any breathing problems or collapse)".
