A case of Egg allergy
-------------------------
Flu or Measles vaccines can not be vaccinated in the child
who have egg allergy. To make influenza vaccine, eggs are
used to propagation of influenza viruses and it is quite
difficult to remove the residue of egg proteins.
Don't worry ! Egg allergy is resolved in accordance with age.
