Some concern is often raised regarding immunisations and allergy risk. This is because the vaccines used contain substances which can cause allergy in some people. For instance, the measles and mumps parts of the MMR vaccine are grown in a substance which may contain small amounts of egg protein.
The single measles vaccine is grown in the same way and is thus not a useful alternative to the MMR. Many studies have shown that almost all children, including those with severe egg allergy, will not react to the MMR vaccine.
Research into how babies and young children have reacted to this safe and widely used immunisation has shown that unless a child has previously had an anaphylactic shock or they have asthma, then no special precautions need to be taken.
It is strongly recommended that all egg allergic children should still receive the MMR vaccination to protect them against these infections.
Having active asthma at the age of receiving MMR is extremely unlikely, but if your child is in this situation the immunisation can be given in hospital. Speak to your baby's GP or allergist about this. However, further research into the need for immunisations being performed in hospital settings has shown that most babies immunised in hospital did not need to be.
All available information about immunisation and allergy points to the fact that immunisation in children who are at high risk of developing allergy is safe and not a factor in their future allergic conditions.
Further information on Immunisation is available in the Pregnancy and the First Year booklet from Blossom's Childhood Allergy Series. For more information on how to receive this and subsequent booklets click here.
