There has been concern that traces of egg protein may be found in measles and mumps vaccines. But these are produced in ****chicken cell cultures****, not in eggs. Studies have shown that people with an egg allergy have not had severe allergic reactions when given these vaccines. Most allergic reactions to measles and mumps vaccines are caused by gelatin or neomycin.

(?) chicken cell cultures = культуры клеток куриного эмбриона

TIA!
