Is it true that egg allergy is no longer considered a contraindication to MMR vaccine?
Several studies have documented the safety of measles and mumps vaccine (which are grown in chick embryo tissue culture) in children with severe egg allergy. The AAP’s “Red Book” Committee no longer considers egg allergy a contraindication to MMR vaccination. The new ACIP statement on MMR also recommends routine vaccination of egg-allergic children without the use of special protocols or desensitization procedures.
