Egg Allergy in Children — Belfast
Private assessment and management of egg allergy in children in Belfast and Northern Ireland. Dr Mugilan Anandarajan, Consultant Paediatrician, offers allergy testing, baked egg tolerance assessment, MMR vaccine advice, and personalised management plans.
About Egg Allergy
Egg allergy is one of the most common food allergies in young children. It is caused by an immune reaction to proteins in egg — primarily in egg white (ovalbumin, ovomucoid, ovotransferrin) but also in egg yolk.
Most children develop egg allergy in infancy, often presenting with eczema flares or reactions when egg is first introduced. The good news is that the majority of children outgrow egg allergy by school age.
Baked Egg Tolerance
Many egg-allergic children can tolerate egg that has been extensively baked (in cakes, biscuits, bread). Tolerance of baked egg is a positive sign and is associated with a higher chance of outgrowing egg allergy. Assessment of baked egg tolerance is an important part of egg allergy management.
Symptoms of Egg Allergy
- Hives (urticaria) — red, itchy raised welts on the skin
- Swelling of the lips, face, or eyes (angioedema)
- Vomiting or abdominal pain
- Runny nose, sneezing, or itchy eyes
- Worsening of eczema after egg ingestion
- Throat tightening or difficulty breathing (severe — anaphylaxis)
Egg Allergy & Eczema
Egg is one of the most common food triggers for eczema in young children. If your child's eczema is poorly controlled, egg allergy should be considered and tested for.
What Happens at the Consultation?
Clinical History
Detailed history of reactions to egg — raw, lightly cooked, or baked. Onset, symptoms, severity, and any treatment given. History of eczema and other atopic conditions.
Allergy Testing
Skin prick testing with egg white and egg yolk. Specific IgE blood tests including ovomucoid (Gal d 1) to assess likelihood of outgrowing allergy and baked egg tolerance.
Baked Egg Assessment
Assessment of whether your child may be suitable for a baked egg introduction, with guidance on how to do this safely at home or in a supervised setting.
Management Plan
Personalised plan including allergen avoidance advice, adrenaline auto-injector prescribing where indicated, vaccine advice, and follow-up review.
Vaccines & Egg Allergy
MMR Vaccine
The MMR vaccine can be safely given to children with egg allergy, including those with a history of anaphylaxis to egg. It can be administered in a standard primary care setting with a 15-minute observation period.
Flu Vaccine
Most children with egg allergy can receive the standard flu vaccine in primary care. Children with a history of anaphylaxis to egg should receive it in a hospital setting. Egg-free flu vaccines are available for those who need them.
Yellow Fever Vaccine
The yellow fever vaccine is grown in eggs and is contraindicated in children with a history of anaphylaxis to egg. Specialist advice should be sought before travel to yellow fever endemic areas.

Frequently Asked Questions
What is egg allergy in children?
Egg allergy is one of the most common food allergies in children, affecting approximately 1–2% of young children. It is an immune-mediated reaction to proteins found in egg — primarily in egg white (ovalbumin, ovomucoid) but also in egg yolk. Most children with egg allergy develop it in infancy and many outgrow it by school age, though some children remain allergic into adulthood.
What are the symptoms of egg allergy in children?
Symptoms typically appear within minutes to two hours of egg ingestion and can include hives (urticaria), swelling of the lips or face (angioedema), vomiting, abdominal pain, runny nose, and itchy eyes. Severe reactions (anaphylaxis) with throat swelling and breathing difficulty are less common with egg allergy than with nut allergy, but can occur. Egg allergy can also worsen eczema in some children.
How is egg allergy diagnosed?
Diagnosis is based on a detailed clinical history of reactions to egg, combined with allergy testing. Skin prick testing with egg white and egg yolk extracts and/or specific IgE blood tests to egg proteins (including ovomucoid — Gal d 1) are used to confirm sensitisation. Ovomucoid-specific IgE is particularly useful as high levels are associated with persistence of egg allergy and intolerance of baked egg.
Do I need a GP referral to see Dr Anandarajan about my child's egg allergy?
No. You can book directly without a GP referral. Dr Anandarajan sees children aged 0–16 with suspected or confirmed egg allergy at Kingsbridge Private Hospital and Ulster Independent Clinic in Belfast.
Can children with egg allergy have the MMR vaccine?
Yes. Current UK guidance (Green Book) states that the MMR vaccine can be safely given to children with egg allergy, including those with a history of anaphylaxis to egg. The MMR vaccine is grown in chick embryo fibroblast cells and contains only trace amounts of egg protein — insufficient to cause a reaction in the vast majority of egg-allergic children. Dr Anandarajan can advise on vaccination in the context of your child's specific allergy history.
What about the flu vaccine and egg allergy?
Most flu vaccines are grown in eggs and contain small amounts of egg protein. Children with egg allergy can generally receive the standard flu vaccine in a primary care setting with a 15-minute observation period. Children with a history of anaphylaxis to egg should receive the flu vaccine in a hospital setting. Egg-free flu vaccines (e.g. Flucelvax) are available and may be recommended for some children.
Can children with egg allergy eat baked egg (in cakes and biscuits)?
Many children with egg allergy can tolerate egg that has been extensively heated (baked), such as in cakes, biscuits, and bread. This is because heating denatures the egg proteins, reducing their allergenicity. Tolerance of baked egg is a positive prognostic sign and is associated with a higher likelihood of outgrowing egg allergy. However, baked egg tolerance must be assessed carefully — not all egg-allergic children can safely eat baked egg. Dr Anandarajan can advise on whether a baked egg introduction is appropriate for your child.
Will my child outgrow egg allergy?
Yes — the majority of children with egg allergy outgrow it, typically by school age. Studies suggest that around 50% of children outgrow egg allergy by age 5, and up to 80% by their teenage years. Children with lower specific IgE levels and those who tolerate baked egg are more likely to outgrow their allergy. Regular allergy review with repeat testing is important to monitor for the development of tolerance.
