Vaccines Often Contain Egg, Can They Cause an Allergic Reaction?

The science of allergy testing is a hot topic right now, with the labelling of food proving a particularly contentious issue. The fear of unsuspectingly suffering a reaction and at worst, anaphylactic shock is a very real one and many people are in need of the facts of how to do everything they can to avoid problems of this kind. Food ingredients aren’t the only thing that people aren’t fully informed about either, as vaccines also contain things that you might not be aware of. As a result, we regularly get asked, “Vaccines often contain egg, can they cause an allergic reaction?”

Read on to take a look at the subject in closer detail.

Albumen (The White of the Egg)

Believe it or not, many of the vaccines we give our kids contain egg albumen, so allergy testing for sensitivity to egg in particular is something that parents should definitely consider. Egg allergies are quite common in children, especially under fives and whilst they often grow out of the issue, if the sensitivity is an acute one, it can result in some unpleasant side effects.

Mild Reactions

In the majority of cases, allergy testing will highlight a mild sensitivity to egg, which when triggered, will result in relatively mild symptoms, including:

Skin rashes

● Nasal congestion



These symptoms will usually appear within a few minutes of ingesting egg and will require the use of antihistamines to alleviate the issue.

Severe Reactions

Whilst the percentage of people suffering from a sensitivity to egg that may experience anaphylaxis is quite small, this will apply to some people. It is this group that is most at risk and for whom allergy testing can be a matter of life or death. If your child is unfortunate enough to be part of this group but you’re not aware of it yet, a trip to the doctors for their vaccinations could potentially put their life at risk – particularly as you’re not yet likely to be in possession of an EpiPen to counteract the reaction.

The symptoms of anaphylaxis include:

● Lightheadedness or dizziness

● Rapid pulse

● Abdominal pain

● Stomach cramps

● Loss of Consciousness

● Difficulty in breathing

Should your child experience any of these symptoms after ingesting egg through vaccines or otherwise, medical attention should be sought as a matter of urgency.

Knowledge is King
